The work I now present to tlie notice of the reader is, I believe, the only attempt which has yet been made to publish a fairly complete account of the Ichthyology of our Indian Empire. I propose, therefore, to preface it by a short sketch of the circumstances which have led to its being undertaken, as likewise by some notice of those zoologists who have preceded me in endeavouring to advance the knowledge of this branch of Natural History in the East ; and I have added comments on such matters connected therewith as seem to be of interest to the scientific pubHc, or relate to the economic value of the Fisheries. It is now many years since I commenced to devote time and no small labour to these subjects. From 1859 to 1862 I was on duty at Cochin, and spent most of my spare hours in collecting specimens of the fish along that coast. The examples secured and preserved were numerous, and the results are embodied in a work, " The Fishes of Malabar," which may perhaps be considered the germ from which the present and more pretentious treatise has taken its origin. The notice of Government was drawn to the subject in the following manner. In 1867 Her Majesty's Secretary of State for India, in a despatch to the Madras Government, directed their attention to a letter from Sir Arthur Cotton, in which he said he " should suppose that the injury to the coast fisheries must be very great, now that seven of the principal rivers on the East coast" are barred by irrigation works that had been constructed. In consequence of this I was directed by the Government to visit the " anicuts " or weirs in the Madras Presidency, in order that the Heads of Departments might have fuller information on the subject than had been offered them up to that date. This order was carried out as follows : — first the districts to the south of Madras were inspected, and then those to the north. I was afterwards instructed to continue these inquiries, and went to Orissa and Lower Bengal, afterwards to British Burma, and at the end of 1869 to the Andaman Islands. An accident which occurred during these investi- gations compelled me to proceed to Europe in March, 1870, but this enabled me to visit many of the fish-ladders in use in England, and I returned at the end of the year to India. My visits to the irrigation works on the rivers of Southern India in 1867, had, however, completely established the fact that the fish which, prior to the erection of the weirs, had ascended the rivers during the season of the rains for the purpose of spawning, were not only prevented from proceeding up stream to spots suitable for the deposition of their ova, but were collected in such vast numbers immediately below these weirs, which they vainly attempted to pass, that the wholesale manner in which they were caught by the native fishermen almost amounted to extermination of the spawning fish of each season. The want of legislation a 11 PREFACE. on the subject was fully recognized, but it was also seen tliat our knowledge of tlie Ichthyology of that part of the world was exceedingly imperfect. Under these circumstances I was oifered the post of Inspector- General of Fisheries, with power, when not required to be present at the seat of Government, to travel about the country and collect information on subjects connected with the Department. My time was spent in these pursuits from January, 1871, to early in 1874, during which period I visited every large river in India, and nearly the entire coast from Gwadur in Beloochistan to Mergui in Tenasserim. This enabled me to form a private collection of many thousand specimens taken from various parts of India, and, I believe, fairly representing the Ichthyology of the lakes and rivers and of the Indian Ocean. The present work contains descrip- tions of 1340 species, 1185 of which are in my own collection: I have also personally examined 111 additional Indian species in other Museums, some of which I have figured: the remaining 44 forms are described from the writings of others, as I have not yet seen examples of them. It is from these matei-ials that I have endeavoured to meet the wishes of Government that I should prepare a woi-k on "The Fishes of India."* It must not, however, be supposed from what I have just stated, that T have any wish to ignore the merits of those Ichthyologists who have preceded me in the treatment of this subject. Science is deeply indebted to those gentlemen, most of whom I will endeavour to specify by name and to add a few words respecting the labours of each. The first writer on Indian Fishes I propose adverting to is Block, whose splendid work on " Auslandische Fische" was published in 1785. It, his " Ichthyologie," and the continuation of this latter by Schneider in 1801, contain many Indian marine forms. To these must be added Lacep'ede's " Histoire des Poissons," 1798-18G3. No small impetus was given to the practice of fish-collecting in India by the publication of these treatises, which fully deserve to receive a large share of praise and respect. Br. Russell, Naturalist to the Madras Government, was the author of the " Fishes of Vizagapatam," wherein 200 forms are delineated and described. The work was published in two volumes folio by the Court of Directors of the Hon. East India Company in 1803. J)r. Francis Buchanan^ (who subsequently took the name of Hamilton) was born at Branziet, in Stirlingshire, February 15th, 1762. Having completed his education and obtained his diploma at Glasgow, he subsequently studied at Ediuburgh, receiving his degree in 1783. He entered the Navy, but had to leave on account of ill-health. In 1794 he was appointed an Assistant Surgeon in the Hon. East India Company's service on the Bengal establishment, and soon after his arrival iu Calcutta he was sent with Capt. Symes on his mission to Ava, and employed his leisure in collecting specimens of Natural History, nut only in Burma but subsequently at the Andaman Islands. He forwarded his collections and drawings to the Hon. Court of Directors, who presented them to Sir Joseph Banks. Eeturning to India he was stationed for two years at Luckipoor, near the mouth of the Brahmaputra, when the fishes of that locality attracted his attention. In 1798 he was sent to examine the district of Chittagong, and the country in the vicinity : here he largely augmented his botanical collections, which * The parts of this work have been published as follows :— Part I, August 1875, to end of page 168, with 40 plates and 130 figures: Part H, August 18"6, to end of page 368, with 41 plates and 148 figures: Part III, August 1877, to end of page 552, with 65 plates and 305 figures, while Part IV contains 61 plates with 343 figures.

PREFACE. 1" were disposed of as his Burmese ones had previously been. Part of 1799 was employed in investigating the Fishes of the Ganges and its branches. In 1800 he was commissioned to report upon the state of Malabar, lately conquered from Tippoo Sultan, when he found three new species of carps. In 1802 he was sent with Capt. Knox to Nepal, of which he pubhshed a history in 1818, but he restricted his Natural History investigations to botanical pursuits. In 1 806 he was directed to make a comprehensive statistical survey of the territories comprising the Presidency of Bengal as well as of some adjacent districts. This occupied seven years, and it is only those who have had the opportunity of inspecting the vast amount of information his twenty-eight thick folio volumes of MSS. contain, that can appreciate the enormous amount of labour undergone, as well as the extreme accuracy of detail which is there displayed. In 1815 he returned to Europe, but the drawings of fish, &c., he was not permitted to take with him ; and subsequently he appears to have been refused access to his original MS. report, when he desired to publish, at his own cost, the " Fishes of the Ganges," which he did in 1822 in one vol. quarto. It contains descriptions of 269 species, and is illustrated by 97 figures. There is no record of his having brought any specimens to Europe.* Cuvier and Valenciennes' " Histoire Naturelle des Poissons" (commenced in 1828, and the last of the volumes of which was pubhshed in 1849) has perhaps done more than any other Ichthyological work in the present century to stimulate a liking for Ichthyology. Mr. J. Bennett, of the Ceylon Civil Service, pubhshed in 1830 a beautifully illustrated work containing coloured figures of 30 of the most beautiful and interesting of the Fishes found on the coast of Ceylon. This was intended as the first instalment of a large work on the subject, which, however, was never completed. Dr. Cantor, of the Bengal Medical Service, was the next Indian author who wrote upon Fish, in a paper in the "Journal of the Eoyal Asiatic Society," 1839, entitled "Notes respecting some Indian Fishes," being observations he had made while discharging the duties of Surgeon to the Hon. Company's Marine Survey. Subseriuently, in 1850, his "Catalogue of Malayan Fishes" was published in the " Journal of the Asiatic Society of Bengal." It contains full and accurate descriptions of 292 species, to which are added 14 plates of fish or anatomical details. His collections became the property of the Hon. East India Company, and were transferred to the British Museumt in 1860. Dr. John McClelland, of the same service, having been attached to a mission sent to Upper Assam in the winter of 1835-36, devoted the time spent on the river to the examination and figuring of species of fish, J and in 1839 published a memoir on " Indian Cyprinidas" in the second part of the 19th volume * See remarks under the head of Blyth, p. v. t The Museum at the India House received in 1819 from Br. HorsfieU some fishes ft-om Jav.a ; in 1823, a collection containing fish sent by Dr. Finlayson, Surgeon and Naturalist to Crawfurd's Mission to Siam and Hue, the capital of Cochin China. Dr. Gn^dh's zoological collections made in Afghanistan, and containing fish, were sent to the same Museum by the Bengal Government in 184a, and the following year he personally presented more. The Asiatic Society of Bengal at several times also sent fishes to the India Museum, and so did the Bombay Government in 1851. Mr. Brian Eodson, of the Bengal Civil Service, likewise presented some Nepal and Calcutta fish to the British Museum. X General BardwicWs " Illustrations of Indian Zoology," edited by Dr. Gray, were published in 18.'50-35. A majority of the Indian fishes are copies from Ham.-Buch. original figures, of which McClelland observes " although they seem to have been withheld from Buchanan himself, the following drawings from his original collection of unpublished figures of fishes have found their way from the Botanic Gardens (in Calcutta) into Hardwicke's Illustrations without any acknowledgment to point out from whence they were derived." A list of some of these figures follows. "Years have elapsed," says Cantor in 1850, "and no explanation has been offered to Mr. McCklland's just observations." The late Dr. J. E. Gray observed (in a letter to myself, dated January 19th, 1872), " Hamilton and Ilardwicke were great friends, and he allowed his artist to make copies of all his fishes from Mysore and other drawings for General Uardwicke, in whose collection of drawings now in the Museum they are to be seen. Mrs. Gray engraved a large number of the small unfigured species from that series but they have not been published." I may add that I obtained a set of these figures along with some of the late Dr. Jerdon's MSS.; there are six 4to. plates containing -46 figures. a * 1^ PEEFACE. of the "Asiatic Researches" (pp. 217-465), with 25 plates, having 103 full figures of fish besides detaHs, 39 as stated by McClelland are copies from Ham.-Buch. drawings. The number of species described is 138. He observes, "I am indebted to the gi-acious consideration of the Right Honorable George Lord Auckland, g.c.b., &c., not only for the opportunity of examining my collection of fishes, which had otherwise been denied on my return from Assam, but also for the inspection of the splendid collection of drawings of the late Dr. Francis Buchanan-Hamilton, which," he continued, " contained 1 14 coloured figures of fish : amongst mammals, 5 of Simia, 5 of FeUnte, 6 Cerrldce ; of birds about 00 of Falconidce, 150 Insessores and 74 Grallae, the whole amounting to about 900 drawings." Subsequently (1841) Dr. McClelland commenced the "Calcutta Journal of Natural History," which extended to six volumes, and in the pages of which are several papers upon the Fishes of India, more especially on the collections made by Dr. Griffith. Many of the specimens were transmitted to the Museum at the India House,* from whence they were transferred to the British Museum in 1859. W. H. Sykes entered the Bombay Army in 1804, when in his fifteenth year. In 1824 he was engaged by Government to assist iu a statistical inquiry, and was thus employed until 1831, when he quitted India as a Lieutenant-Colonel. He made a report that same year to the Court of Directoi-s of the East India Company upon the " Fishes of the Dukhun," accompanied by some good drawings and also specimens. These were left unnoticed until 1838, when they were, at the author's request, transferred to the " Zoological Society of London," who published them in their Transactions, vol. ii, 1841, pp. 340-378. They contain descriptions of 46 species and give 28 figures. Some of the fishes, without any labels, were transferred to the British Museum in 1860 from the India Ofiice. Other specimens, perhaps skins, were wanting ; they may have been presented elsewhere or retained by the author. Dr. Wyllie entered the Madras Medical Service on June 11th, 1812. He contributed a paper on the accessory breathing apparatus of Silurus singio to the " Proceedings of the Zoological Society of London " in 1840, p. 34. He sent to Europe some stuffed fish, now in the British Museum. Dr. Pieter v. Sleeker was born at Zaandam, in Holland, July 10th, 1819. He was apprenticed to an apothecary from 1834 to 1837, in which latter year he commenced his studies at Haarlem, where he graduated in 1840 and received his diploma. At the end of 1S40 and the commencement of 1841 he spent six months at the Paris Medical School, and when iu that city appears to have ucqun-ed a taste for Ichthyological pursuits. May 24th, 1841, he obtained entrance by public competition into the Army Medical Department, embarking for Batavia iu November, and arriving there March 13th, 1842. He returned to Europe in 1860, and was placed on the pension establishment, April 1st, 1864. He collected in the East and brought in safety to Europe large zoological collections, that of fishes alone exceeding 30,000 examples. His papers upon the Fishes of the East are too numerous for me to give the titles. In 1853 he published a paper on the " Ichthyologische fauna van Bengalen," pp. 162, with lists of all the fishes previously described from India, and detailed descriptions of 162 species. In 1862 he gave descriptions of 11 species of carps from Ceylon, which had been sent to the Leyden Museum: his paper has 4 plates illustrated with 11 coloured figures. His magnificent "Atlas Ichthyologique des Indes Orientales Neerlandaises " must ever remain as a lasting testimony to his unwearied industry, scientific acquirements, and accurate determination of species. Unfortunately his sudden death, on January 24th, 1878, occurred when he had only completed eight out of the twelve volumes; and though much of the remainder is left in a forward state, it is to be feared that circumstances may prevent its publication being completed. * List in " Cal. Journ. Nat. Hist." ii, p. 573. PREFACE. V Mr. BIyth, the able Curator of the Museum of the Asiatic Society of Bengal, gave several interesting articles in their Proceedings on the Fishes of India: in 1858, remarks on some Fishes from the Andamaus, pp. 270-272 ; Fishes from Pegu, Calcutta, and elsewhere, pp. 281-290; Fishes of Pegu, 1859, p. 297; The Cartilaginous Fishes of Lower Bengal, 1860, pp. 35-45; On some Fishes fi-om Port Blair, 1860, p. Ill; On some Fishes of the Tenasserim Provinces and Lower Bengal, 1860, pp. 138-174. He sent a number of fishes, personally collected, to Europe, and he informed me that he entertained no doubt but that in the " collection of Fishes from Bengal, believed to contain many typical specimens of Buchanan-Hamilton's work, presented by G. R. Waterhouse, Esq." to the British Museum,* were some which had been sent by him to England. Having been permitted by Mr. Winter Jones to examine the register, I find the majority of the generic names under which they were received as AUla, Amhassis, Amhlyopus, Apocryptes, &c., were not invented until after Buchanan's death. Col. Tickell, of the Bengal Army, gave a paper on Astheniirus atripinnis to the " Journ. Asi. Soc. of Bengal," 1865, p. 32, pi. i. He also sent large collections of fish to the Calcutta Museum, and has left a MS. volume of beautiful drawings of fish with descriptions. Br. Thomas Caverhill Jerdon, so well known as the author of the standard work on " The Birds of India," 3 vols., and another on " The Mammals," 1 vol., devoted some time to Fishes. The first part of his " Fishes of Southern India" was published in the " Madras Journal of Literature and Science," vol. xv, 1849, p. 139 to 149, and contained descriptions of 22 species, 3 of which were stated to be new. The second part was also in the same volume (p. 302 to 346) ; it contained descriptions or references to 150 species, 55 of which were believed to be new. In 1851 he gave another paper to the same journal, entitled " Ichthyological Gleanings in Madras," p. 128 to 151, it contained references to 391 species obtained during a two years' residence in Madras. A considerable number at that time were unknown to science, but he refrained from naming them, which has been subsequently done by others. He had coloured figures made of large numbers, and presented some fine stufi'ed specimens to the British Museum. Br. Giinthcr, of the British Museum, has considerably facilitated the study of fish by compiling a " Catalogue of the Fishes in the Collection of the British Museum," eight volumes 8vo. 1859 to 1870, published by order of the Trustees. The work is said to contain 6843 well established and 1682 doubtful species. The " Fishes of Zanzibar," published by the same author in conjunction with Col. Playfair, must also be alluded to, as it supplies a list of 500 fishes found along the East coast of Africa. It contains 22 plates and 67 figures of fish, some of which are simple outlines. The specimens, mostly dried skins, are in the British Museum. Br. Klunzinger has given two excellent papers upon the Fishes of the Red Sea in " Verhandlungen der k.k. zool-bot. Gesellschaft in Wien," 1870, pp. 669-834, and 1871, pp. 441-688. Some of his specimens are in the British Museum. It is my pleasing duty to offer ray best thanks to the many friends who have afforded me assistance in order that I might complete this work in a satisfactory manner, and amongst my official superiors more especially to General R. Strachey, r.E.s., and A. 0. Eume, Esq., c.B. Amongst those who have given me help in the East, or furnished me with materials they have collected there, I must especially mention Sir Walter Elliot, K.c.s.r., formerly of the Madras Civil Service, who most libirally placed at my disposal the whole of his beautiful and accurate coloured illustrations of the Fishes of Madras and Waltair which he had had executed by native artists from the fresh specimens. These comprise many hundred species, each with its native name attached, as well as Jerdon's identifications, thus giving me the key to the fishes recorded in "Ichthyological Gleanings in Madras" (M. J. L. and S., 1851). * British iluseum Catalogue, iii, isei, p. iv. yi PREFACE. Besides this he has obtained for me a few of Jerdon's original type specimens, some of which I have had fio-ured, also a good number of MS. notes, as well as Cantor's MS. opinions upon the sharks and rays. It will be seen in the pages of my work that I have quoted largely most interesting details from some of these ; and I hope before long to complete a coloured series of the Fishes of India, which I could hardly accomplish in a satisfactory manner were it not for Sir W. Elliot's assistance. Hennj Sullivan Thomas, Esq.* Madras Civil Service, the author of a most able and exhaustive report on " Pisciculture in South Canara,"t has given me very great assistance, not only in collecting laro-e numbers of beautiful specimens from the fresh waters of Canara as well as from the sea, but also in ascertaining a great deal respecting the habits of fish, their breeding, and what a lamentable necessity exists for legislation with respect to the finny tribes. He has had a few excellent coloured figures of some fresh-water fishes executed for me by native artists, and also sent me a collection of the Fishes of the Shevaroys, some from Madras, and the first example of a trout bred in India in a wild state. The late Dr. Ferdinand Stolicz'ka,X the able and energetic Natural History Secretary of the Asiatic Society of Bengal, assisted me both while collecting and also in obtaining specimens from localities I did not visit. His first large collection of fish was made at Penang, and on his return voyage by the Nicobars and Andamans: in the cold season of 1871 he obtained 18 species while on a tour through Cutch (" Journ. Asi. Soc. of Beng.," 1872, pp. 258-2G0) : in 1873 he went as Naturalist with the expedition to Yarkand; the collection of fish which he then made comprised 22 species, out of which 9 were new (" Proc. Zool. Soc. of London," 1876, pp. 781-807). I have likewise to oSev my thanks to Br. J. Anderson, of the Imperial Museum at Calcutta, for affording me every facility towards examining its most interesting Ichthyological collection, as well as for obtaining and transmitting to me in this country some species I wished to dissect ; also to Mr. J. Wood-Mason, of the same institution, who assisted me in my collections. Br. Buka and Br. Govan kindly collected for me at Almorah and Darjeeling, Br. Wright in Nepal, Major Puchle^ in Mysore, H. E. Watson, Esq. in Sind, and Col. SJa,den at Mandalay in Upper Burma, while Capt. Neill and Br. Caldecott, of the 1st Central India Horse, sent me a small collection of fishes from Agur. Br. Bidie gave me leave to freely examine the specimens in the Government Central Museum at Madras, and likewise had a collection made for me during my absence. Br. Keess, the Garrison Surgeon, kindly superintended the work of a native collector. Irrespective of those enumerated there are many others who have assisted me with specimens or in various other ways, to each and all of whom I beg to tender my acknowledgments. In Europe I have more especially to thank Professor Peters, Director of the Berlin Museum, who not only most freely gave me access to the valuable contents of the magnificent collection of fishes under his charge, but has also aided me in my difficulties aud assisted me with regard to Bloch's type specimens. * Author of " The Rod in India," or hints how to obtain sport, with remarks on the Natural History of Fish, Otters, &c., 8vo., Mangalore, 1873, pp. 319.

His earlier professional career was passed in tlie Imperial Geological Institute of Austria, where he became greatlv distinguished by his palsontological work. In 1862 he accepted the appointment of Pala-ontologist to the Geological Survey of India. He was selected as Katnrabst to accompany the Yarkand Mission. In accepting this post he was made fully aw.are of the risk he was running, his health never having been completely restored after an expedition he had undertaken some years previously to the higher regions of the Himalayas. tJn the return of the Mission from Yarkaud he pcrislied, due to the extreme cold at the summit of the Karakorun Pass, June 19th, 1874. § Author of a paper entitled " Fresh-water Fu-h. in and about Bangalore,'' folio, 18GS, pp. 12. PREFACE. VJI « Among the Officials at the British Museum, I must record my acknowledgments to Professor Owen, c.B., Mr. Winter Jones, and the late Dr. J. E. Gray, for such help as they were able to afford me to obtain free access to the Ichthyological collection. At the Hague, the late Dr. Bleeker, not only permitted me free access to his invaluable Ichthyological Museum (containing about 2000 species),* his notes and his unpublished figures of fish, but he also assisted me with his opinion, on the validity of species as well as presented me with many of his types. lu him I have personally to deplore the loss of a kind friend, and one who stood unrivalled among the Ichthyologists of the present time. Professor Schlegel, the Director of the Leyden Museum, and his able Ichthyological assistant, Dr. Hubrecht, have rendered me invaluable assistance. The latter, as may be seen in the pages' of this work, has been indefatigable in searching out superior examples of such fish as I desired to figure, but of which I did not possess sufficiently good specimens. At Paris, I have to offer my thanks both to M. VaUlant and Dr. Sauvage, who most kindly assisted me at the Museum in the Jardin des Plantes, more especially in respect to the type specimens of Cuvier and Valenciennes' great work on Fishes. I cannot resist noticing here how excellently preserved and scientifically registered the fish in that unrivalled Ichthyological Collection are. I have also to give my best thanks to A. G. Brisbane Ncill, Esq., of the Madras Medical Service (retired), for his valuable assistance in carrying this work through the press, a labour which can scarcely be appreciated except by those who have undertaken similarly arduous tasks.

INTRODUCTION. Prioe to commencing an account of the fishes existing in India and Burma, it will be necessary to define the Geographical limits of the countries or seas the Ichthyology of which I propose to describe. They may be brieflj- summed up as the regions of Sind, India, Ceylon, Assam and British Burma extending eastwards to Mergui in the Tenasserim Provinces, and including the Nicobar and Andaman Islands in the Indian Ocean. The boundaries are the Beloochistan and Sulieman ranges of mountains on the West and North- West, the Himalayas and Upper Burma on the North and North-East, and the Indian Ocean to the South. Within the foregoing area we find, as might be anticipated, vast difierences of climate as well as of locality. The rivers vary in their conditions owing to the season of the year, the rainfall, and other circumstances, both natural and artificial. Some rivers, as those which descend from the Himalayas, possess Alpine sources, and in the hot months of the year are chiefly fed by the melting of ice and snow, while in the monsoon season they are filled by the rains. Thus in the commencement of March, floods begin in the Indus, when inundations are more due to melting snows than to the fall of rain ; on the contrary, in the upper regions of the Ganges and Jumna, the rainfall is very considerable, occasioning floods, which subside as rapidly as they rise. During the cold season these rivers being unreplenished by rains or melted snows, are at their lowest. In rivers destitute of Alpine sources, as the Nerbudda, Kistna, Godavery, and those arising on the Western ghauts or lower hill ranges, snow rarely falls and never remains for any length of time. Along with these must be classed as being of the same character, the affluents of the larger snow-fed rivers, and it is in such where the temperature of the water is higher, that most of the hill fishes (excepting some loaches and perhaps the Schizothoracincc) breed. If we take as an example the rivers on the Malabar coast, which as a rule have their origin in the Western ghauts, we perceive that they receive the full force of tlie South- West monsoon, which commencing in June, continues about three months. It is only at this period of sudden rises and falls of the river, that breeding fish can ascend to the hill ranges for the purpose of depositing their ova in suitable localities. As the monsoon ceases, the waters subside, and the breeding fish descend to the plains, leaving the young to be reared in the pools remaining in the hill streams. The rivers of the plains may be divided into those which have always a fair supply of water, as the Indus, Ganges, Brahmaputra and Irrawaddi : and others which are comparatively dry during part of the year. In some of these latter this deficiency of water is increased by what remains being abstracted for irrigation purposes. t During the rainy months of the year rivers are usually at their highest, submerging the contiguous country, and filling the numerous tanks : here many fish retire to breed and are entrapped by every device the ingenuity of man can conceive. Weirs or bunds, as I have observed, affect fisheries by preventing the ascent of breeding fish to their spawning grounds. Irrespective of this, any descending a river and arriving at a weir, find an obstruction to their further progress down stream, but a large quantity of water being deflected from its natural course down an irrigation canal, they as a consequence descend by this the only open route. Once down a canal and over a single fall, there is no possibility of their return, and as these canals are being constantly dried in order that the engineers may examine their structure, they become vast traps for the destruction of the finny tribes, as successive waves of living fish pass down them only to die. We find the same process going on elsewhere, although to a less extent. Thus in Malabar as the dry season commences, water is required to irrigate the second rice crop ; but the rivers are very low, so the farmers collect stones, lay them across the stream, filling in the interstices with shingle and stopping up the crevices with bushes and mud. In this way the water which is stocked with fry is diverted into rice fields : the young fish pass in to these levelled and partitioned localities, and if the water does not return to the river, but is expended in the fields, they cannot escape destruction. Even if it does return to the river, fine traps which do not permit the smallest fry to escape are fixed in every constricted place. If we examine into what are the fish which inhabit these pieces of fresh water as well as the tanks, lakes, and marshes of India and Burma, we find most diversified forms. Some are exclusively confined to the fresh waters, while others enter rivers from the sea for breeding or to catch their prey. The subject of the migrations offish during the rains is of importance, being mostly effected for the h X INTRODUCTION. purpose of breedins^. At the commencement of the rains they become very excited, apparentlj^ unsatisfied with the localities they inhabit, they restlessly seek a change. It is generally at this season that some have been observed travelling on land, and it has been imagined that places which are only now and then covered by water become peopled by tish in this manner after heavy showers of rain The modes of respiratiim in some of these fishes are exceedingly curious, and have a bearing upon the question of migration. We find respiration carried on in three ways : — First, as is usually observed elsewhere, oxyo-en is obtained from air in solution in the water and which is separated at the gills, as by carps and most siluroids. If such fish have a bandage stitched round their gill-covers precluding the use of the gills, they die owing to the impossibility of taking in oxygen as described : on the same principle if the water becomes vei-y muddy their gills become choked, respiration impeded and death ensues.* Secondli/, we have forms on which muddy water does not produce an injurious efiect on placing a bandage round the gdl-covers. They never obtain oxygen for any length of time fi-om the air in solution in the suiTouuding water, but inspire it direct from the atmosphere, no matter how cool and charged with air the water may be : if unable to inhale atmospheric air they become poisoned by the carbon remaining in their circulation. Such fish are to be found in the amphibious forms of Anahas (p. 369), Pohjacanthus (p. 371), Trichogaster (p. 373), Ophiocephalus (p, 362), Saccobranchus (p. 486), etc. These fishes rise to the surface, expel a bubble of air, and at the same time take in a fresh supply (see p. 439), and this mode of respiration enables them during periodic dry seasons or in the rains to migrate from pond to pond in search of food, or to ascend small water-courses to breed during seasons of inundation when the stream is frequently intermittent. Thirdhj, there are fish which appear to swallow air, as the loaches and spined eels (Rhynchobdallid^, p. 338), but no special air-breathing apparatus has as yet been detected, except that some species are stated to have portions of the intestines lined with vascular papillfe, where oxygen is abstracted from air which is first swallowed and subsequently returned by the mouth or by the anus. A curious phenomenon in Indian fishes is the appearance of adult and healthy ones after heavy falls of rain in localities which had been dry for months previously. If when water failed in India, all the fishes in tanks which dried up were to die, none would be found for the succeeding year's supply unless migrations took place from other localities. As I and others have personally seen live fishes dug up from the ground where a tank had dried up, I do not think we are justified in rejecting the native theory that they become torpid in the mud where they wstivate. As the water in tanks becomes low, the fishes may be perceived congregating in holes and places where their backs are barely covered : if disturbed, they dive down into the thick mud so that a net is often inefi'ectual to capture them. As the water evaporates they become increasingly sluggish, and finally there is every reason to believe that some at least bury themselves in the soft mud and await in a state of torpidity the return of the next season's rains, as is weU known to be the case in animals which possess a higher vitality, as Batrachians, some of the Crocodiles : also molluscs and land snails amongst the invertebrata. It may be that ova of these fishes are in the mud of these tanks with their germination retarded as we know can be accomplished by means of ice. However this may be, a few days after the rains we find numerous fry in many inundated spots. The strictly fresh-ivater forms are divisible into those which are comparatively stationary or non- tnigratory, and secondly the migratory forms which find the waters of the plains unsuitable for the deposition of their ova, or else change their residence in order to obtain some peculiarly desirable description of food. We may, therefore, first briefly allude to the breeding of the non-migratory fresh-water forms of the plains, some of which are monogamous others polygamous. The ubiquitous and amphibious walking fishes, Ophiocephalidj;, are among perhaps the best known of the monogamous species, which as a rule do not produce such a number of ova as the migratory forms, but appear to breed oftener. Some deposit their ova in tanks, others prefer rivers where they live in deserted holes they find in the banks. When the fry are hatched they are defended by their parents until old enough to protect themselves. The polygamous non-migratory fishes of the plains are very numerous, and do not migrate any long distance for the purpose of breeding : in places the smaller carps are innumerable. All these forms during the rains pass up small water-courses in order to deposit their eggs in irrigated fields, flooded plains, temporarily formed tanks, or along the grassy banks of flooded rivers. Of the migratory fresh-water fishes we have those which restrict their migrations to localities in the plains and others which a.scend to hill streams to breed. These latter forms, as might be anticipated, are as a rule larger and stronger than the non-migratory, and they appear to return to the hill ranges to deposit their ova as naturally as some marine species enter fresh waters for this purpose. Of the Anadromous, or migratory marine forms which ascend rivers in order to deposit their ova in suitable spots, we have a good example in the Hilsa or Shad {Clupea ilisha, p. 640). Weirs now form an insuperable bar to their ascent up some of the rivers. The fry of the polygamous fresh-water fish have certain natural laws of protection. Thus they are safe from their voracious parents in hill streams and rivers, as those localities being unable to supply food to the mature forms they, having deposited their ova, drop down again into the rivers of the * If numerous fish are seen de.ad on the lianks of a flooiletl Indian river, it may be simply due to their gills having been choked by mud : should any amphibious forms however be perceived, other causes must have been in operation as poison whether introduced by man or the addition of water from jungles where it bad btcooje imprcguaied with poisonous vegetable substances. INTRODUCTION. ' ^^ plains. On the waters subsiding the fry likewise migrate down stream, but in a much more gradual manner : on the Himalayas they are often detained in the pools of the streams throughout the dry months, being unable to descend until the next year's rains. The same thing obtams an the low country in a modified form, where the fry are found to abound in flooded localities, and durmg the rams e^•e^y little stream and piece of water connected therewith is resorted to by them to obtain food m. They are also found in sheltered spots at the edges of rivers and in shallow pieces of water where there is no current to wash them away. . a i j c i j During seasons of inundation many fish ascend small channels into irrigated or flooded helds for the purpose of breeding : at these times they appear to have lost much of their natural timidity and are only solicitous to reach a suitable locality to deposit their ova. During this period they are trapped throughout the length and breadth of India and Burma. Fishing weirs are permitted to extend across rivers, and "as the waters from above become unwholesome, fish attempt in vam to descend, but the owners of these weirs allow no passage, and as they die in myriads, cart them off as manure^^ (Oflicial Report). " Damming, lading out and poisoning waters are freely resorted to for fishing purposes. In Oudh " the reports from four native officials give 68,300 maunds of fry as yearly killed m then- district alone." In the Madras Presidency the size of the mesh of the nets employed at the period the fry are about is variously reported as follows : Will catch a black ant, detain a mosquito, or even capture a fish eo-g. In Assam, it is stated, " in the shallow waters in the rice-fields women and children may be° seen in crowds fishing with baskets, through the interstices of which a tadpole could not pass Those that escape this danger, and following the flow of water, an-ive at one of the innumerable little bunds separating the various paddy-fields, find their further progress barred by funnel-shaped bamboo traps, through which the water is made to pass, but whose outlets are so small that only the most minute fish can get through. Escaping to the smaller water-courses their dangers seem to increase. The channels are divided into sections by erecting bunds, and from one of these they proceed to bale out all the water, capturing every fish, large and small : they then form another bund and bale ofi^ another portion in its turn. The fish finally arriving at the smaller rivers find their exit barred by weirs which will let nothing pass, and not content with this, the Assamese will sometimes resort to poison." _ . ■ , The fixed engines are mainly constructed of cotton, hemp, aloe fibre, coir, or some such elastic material : or else of split bamboo, rattan, reed, grass, or some more or less inelastic substance. The mesh is so minute that in places water may be said to be strained through it. A common plan is to fix across a river a net shaped like a wall with a bag in the centre ; towards this all the fish are driven, or even a second net is dragged towards it. Fine-meshed nets are even attached to the sluices of tanks, or to wherever water is let out of a field. In hilly districts until the first rush of the water has subsided the weirs cannot be employed, but after that they come into use, and the fish descending from their spawning beds are entrapped. In short, every conceivable variety of trap is employed by the agriculturists, while sniall nets or baskets of various forms and shapes are hung over weirs just above the water: breeding fash finding this barrier in their way try to overcome it by jumping, and many are captured by falhng into ^"nP^P POTlt'Fl VfljTlCGS Movable fishing implements, as nets with various sized meshes, are used much as follows. When the fry are first moving about, those having a minute mesh are employed to capture the tiny creatures : as the fish become larger the size of the mesh of the net increases : small wall nets are dragged up water- courses where fry abound : purse nets are employed in similar localities. Or these movable mplements may be composed of inelastic materials as already described, while some weirs are thus formed. Of the native ofiicials reporting upon the size of the mesh or interstices of these constructions, 91 replied as follows : 5 gave the interspace between knot and knot at 1 inch : 5 at less than 1 inch : 18 at 1/2 an inch : 5 at 1/3 of an inch : 24 at 1/4 of an inch : and 34 at from 1/5 to 1/32 part of an inch. Rivers are sometimes diverted in order to capture the fish, or streams if sluggish are dammed and laded out, or waters are poisoned, the captures being sent to neighbouring villages for disposal, ^ight- lines, spearing, shooting, are all in vogue to obtain the fresh-water fish. One mode ot employing hooks is to fix a row on a line in a pass in a hill stream, when if the waters are very muddy some fash are hooked as they attempt to ascend to their spawning-beds or to descend after breeding : others escape horribly injured. The right of " snatching" appears to have been sold in some places by the revenue authorities; this right or amusement is thus described. A cord is armed with large iron hooks at intervals of two or three feet, by means of bits of wood they are retained with their points uppermost^ This line is thrown across a stream and kept about two feet below the surface, a nian on each bank holding either end. Then other persons with poles beat the water and drive the fish up stream, and as one is seen passing over this inhuman instrument of capture, the cord is jerked m order tiiat a hook may transfix the game. Dexterity is said to have resulted from constant practice ; many hsh are thus captured, but more perhaps get away crippled to sicken and die a lingering death.* Of the vermin which destroy fish we have many forms, but none that approach destructive man who appears to be attempting to exterminate the supply. There is the fish-eatmg or long-snouted * For the different poaching practices to catch fish employed in India and B "Fresh-water Fibljer}- lieport," 1873. ;urma and remedies proposed, see h * xii INTRODUCTION. crocodile, Gavialis Gangeticus, Gmelin, which attains upwards of 20 feet in length and is found throughout the Indus, Ganges, Jumna, Brahmaputra, Mahamuddee and their affluents. Native fishermen do not destroy them, looking upon them as fellow sportsmen. The snub-nosed or man-eating crocodiles, Crocodilus palustris, Less., and G. porosus, Schn., are found in most parts of India, and assist in depopulating the waters of fish. Otters do a considerable injury to fisheries, especially in hUl streams, but I have observed one redeeming point : they destroy the large frogs which cause great destruction amongst fish ova and fry in the paddy-fields. There are many other minor enemies, as wading birds, snakes, tortoises, turtles, and the Gangetic porpoise, Platanista Gangetica. But the question comes. Of what econonic value are these fresh-ivater fisheries? and What proportion of the native population of India and Burma employ fish as food ? Fish enter more into the diet of the urban than they do into that of the rural population in India, as in the former localities (if we except the Brahmaus), its consumption is only limited by the amount of the supply and the cost of the article. I extract the following from official returns. In Sind fish is generally eaten except by Brahmans : in the North- West Provinces containing about 28 millions of people, out of 20 returns received, 17 give more than half the population as not forbidden by their religion to eat fish: and the same is observed in Oudh, the Bombay Presidency, Mysore and Coorg. In South Canara the collector estimated those who eat fish at 89 per cent, of the population : in Bengal proper 90 to 95 per cent. : in Assam and Chittagong nearly the entire population : while in Burma it is universally consumed in the form of nga-pee.* How are the marlcets supplied ? Out of 243 returns made by officials from the Punjab, North-West Provinces, Sind, Oudh, and the other localities already referred to, 180 observe that the markets are insufficiently supplied : 7 that they are occasionally : 3 that they are fairly so : 45 that they are fully so, but 9 of these remark that it is chiefly with marine forms which often are salted : while 8 are doubtful. Thus the markets fully supplied are not one-fifth of the total, and one-fifth of these obtain their supply from the sea. If we now turn to the Geographical distribution of the fresh-water fishes of India we perceive that more than one theory has been advanced in order to explain how vertebrates obtained access to Hindustan. Mr. Wallace remarks that "the great land masses of the Northern hemisphere are of immense antiquity, and the area in which the higher forms of life were developed. In going back through the long series of Tertiary formations in Europe, Asia and North America we find a continuous succession of vertebrate forms including all the highest types now existing or that have existed on the earth. * * That here alone were developed the successive types of vertebrata fi-om the highest to the lowest," and successive waves of life swept southwards. " During the Miocene period, when a sub-tropical climate prevailed over much of Europe and Central Asia, there would be no such marked contrast as that which now prevails between temperate and tropical zones; and at this time much of our Oriental region, perhaps, formed a hardly separable portion of the great Paliearctic land. But when from unknown causes, the climate of Europe became less genial, and when the elevation of the Himalayan chains and the Mongolian plateau caused an abrupt difference of climate on the northern and southern sides of that great mountain barrier, a tropical and a tempeiute region were necessarily formed : and many of the animals which once roamed over the greater part of the older and more extensive region, now became restricted to its southern or northern division respectively. Then came the great change we have already described opening the newly-formed plains of Central Africa to the incursions of the higher forms of Europe ; and following on this, a still further deterioration in climate, resulting in that marked contrast between temperate and tropical faunas, which is now one of the most prominent features in the distribution of animal as well as of vegetable forms." Several good zoologists have considered the African element to be very largely represented in India, or as observed by Mr. Blanford (Ann. and Mag. 1876, p. 294), its vertebrate fauna contains three elements, derived at three ditferent periods from countries which were or had been in connection with Africa. The first of these consists of the forms common to the Ethiopian and Oriental region. These are in India the bulk of the fauna. The second consists of forms common to the Ethiopian region and India, but which do not extend to the Eastward of the Bay of Bengal : nor are they represented in the portion of South- western Asia now lying on the direct line between India and Africa. The third is composed of species with Ethiopian affinities which may have wandered into India from Arabia and Beloochistan. Some insight into the tenability of the foregoing opinions may perhaps be found in briefly examining the distribution of the fi-esh-water fishes at present existing. Although mountain chains or sandy deserts may be insuperable obstacles to the extension of fishes in certain directions, no less impassable * Ngapee is a Burmese term employed for a preparation of fish or crnstacca. If fish are the constituents they may be employed whole or pounded. The general mode in the former is to cnt off the head of the lish. and if large it is split in two, cleaned, dried a few hours in the sun : salt is now rubbed into it, and it, along with others, is packed into a jar, from which they are removed the next day and treated m a similar manner. In large ti.sheries where many have to be preserved, a hole is dug in the ground where tliey are placed in long bamboo baskets in alternate layers of fish and salt aud the whole buried for some time. There are many modes of preparing Ngapee. Of this substance the Chief Commissioner remarked : — " The quantity consumed in our territory is not known accurately, hut the average yearly export to L'jipcr Burma during the past four years has been upwards of 716,0(10 tons, with a value of £170,000; aud the home cousuniptiou in British Burma is certainly far greater than the quantity exported." INTRODUCTION. xiii to the fresh-water species is a tract of salt water, or a narrow arm of the sea. It is absolutely essential for the migrations of these fishes that fresh-water continuity should be unbroken, while to admit this it seems reasonable to insist that a land connection must have been present for the existence of the fresh-water to be possible. If, therefore, forms of fre^b-water fishes are found in the islands of the Indian Ocean identical with those on the mainland, it does not seem unreasonable* to suppose that the two localities have been connected one with the other at some antecedent period. Of the 87 Genera of fresh-water fishes to which I have to allude, we find the distribution to be as follow : — 5 restricted to the Himalayas or Tartarian forms. 69 in Hindustan ; of these 38 extend to the Malay Archipelago. 8 restricted to Ceylon, of which 4 are found in Burma and 5 in the Malay Archipelago. 5 in Burma, 4 of which extend to the Malay Archipelago. Out of those genera which are extended from India to the Malay Archipelago, 12 are common to Africa, India, and the Malay Archipelago : while 2 only are restricted to Africa and India, and both these forms are found in the intervening Mediterraneo- Persic sub-region. In the Indian fresh-water fishes of the present period, the Malayan element is far more developed than the African. Of the 14 Genera at present existing in both Africa and India, we find that 9 are strictly confined to fresh waters, as in them there are no species which reside in the seas or estuaries : of these 7 are lilcewise found in the Mediterraneo-Persic sub-region, and it is therefore reasonable to suppose that it may have been by that route that they obtained access into India. Of the sub-regions of India and Burma we have first, the Geylonese, extending from Goa down the Western coast of India including Canara and Malabar, with the Western ghauts, to Ceylon : passing along the Neilgherries, its piscifauna joins with that of the Hindustan sub-region in Mysore, while in the Carnatic°it in like manner passes as far as the river Kistna. 27 Genera of fresh-water fishes have been found in the island of Ceylon, all but one of which (Ghanna) are common to the mainland. This Geylonese sub-region possesses several elements in it which appear to point out the advisability of separating it from that of the plains of India. Thus we find the Genera Pristulepis and Sicydium in Malabar or Canara, absent from the plains of Hindustan, but reappearing in Burma: the Ophiocephalus micropeltes and the siluroid Glarias Dussumieri, have a nearly similar distribution. Ghanna is restricted to Ceylon and China. Polyacanthus is found in this sub-region, but elsewhere nowhere nearer than the Malay Archipelago ; in fact one species is restricted to the island of Ceylon and to Java. Silurus in the Western ghauts and Himalayas, but not in the Hindustan sub-region. The Cyprinoid genus Hoinaloptera has two species on the Western ghauts identical with those on the Himalayas, but the Genus is absent from the intervening country, being otherwise restricted to Burma and the Malay Archipelago. Genus Scaphiodon extends from "Syria to Siud and along the Western ghauts of India. The siUiroid Genus Englyptosternum is found both in Syria and along the base of the Himalayas. The Genus Etroplus is restricted to this sub-reo-ion, but a nearly allied form has been found in Madagascar. These few facts may be variously interpreted, but they appear to show that from Syria and the Mediterraneo-Persic region we have Northern forms extended along the Western ghauts of India and likewise along the base of the Himalayas. They also seem to demonstrate that some close connection must have existed in times gone by between the Geylonese and Malayan sub-regions. The Hindustan sub-region is that large alluvial tract which extends from the Himalayas and the mountain ranges of Sind southwards to meet the Geylonese sub-region, it also embraces the valley of the Brahmaputra. Out of the 69 Genera of fresh-water fishes found in this area 64 extend to Burma, and 38 of these to the Malay Archipelago, while 15 are common to the Patearctic region ; and there is, as might be expected, a larger proportion of Burmese forms in Assam than elsewhere in India ; while the Genera restricted to the area of this sub-region are no more than 5, and, with the exception of Sisor, it possesses no well marked local forms. . . The Himalayan sub-region cannot be included with that of the plains of India; it is true that some varieties of fish ascend there to breed or even to reside there. Finding tropical valleys in the.se elevated districts suitable to their necessities, it is not surprising that following their prey up the streams, they may have been cut off from a return to the plains. Some of the tropical forms which are found there have become modified for a life in hill torrents as Pseudecheneis (p. 500), which possesses a sucker formed of transverse folds situated on its chest between its pectoral fins and by aid of which it keeps itself from being washed away : Ghiptosternum (p. 496) is another .siluroid genus, also with an adhesive sucker on the chest, but with longitudinal folds : the fish of this last genus (although some are found in the Himalayas) seem to be adapted more for rapid rivers of the plains : Exostoma (p. 501) is another remarkable form extending along the Himalayas to Thibet and China, as well as the spur or continuation southwards through Burma and Siam. But once near the summits of the Himalayas, we come across the true Tartarian or Turkestan forms. Here there are carps which have but little relationship * 1 omit from this di.^cnssinn the oft-repeated tale of geese swallowing fish egg?, which were subsequently voided uninjured and with ihcir vitality imimpMi.ed !

The Schizothoracinj: or Hill barbels are carps more or less covered with minute scales or destitute of any. They have a membranous sac or slit anterior to the anal tin, which is laterally bounded by a row of vertically placed scales, like eave-tiles, and which are continued along the base of the anal fin. They are conhned to cold regions or at least to localities possessing snow -fed rivers, many of which rivers end in lakes and do not go to the sea. They extend from Eastern Afghanistan and Western Turkestan through Tibet and the most westerly districts of China. One of the Genera (Oreitms) having a sucker behind the lower lip is able to exist in the rivers of the sub-Himalayan range. Here then is a group of fish which has not spread to the alluvial plains of India from the Himalayas, they being evidently residents of cold climates. Burmese and Siamese sub-region. — Of this it is merely the Western portion or that of Burma that claims our attention. In it we find 63 Genera of fresh-water fish recorded : 4 are found in it and in the Ceylonese, but not in the Hindustan sub-region, 5 are restricted to Burma : and .54 are common to it and to the Hindustan sub-region : out of the 63 Genera 41 extend to the Malay Archipelago. But it must not be overlooked that I have included Assam in the sub-region of Hindustan, and for the following reason, owing to the Brahmaputra river entering the Gangetic system, an easy mems exists for enabling fishes to belong to both deltas, in fact very many forms appear to be found in the three large watersheds of the Brahmaputra, Ganges and Indus. Similarly we find the fish-eating crocodile Gavialis Ganiieticus common to all, but not extended to the Ceylonese sub-region nor to Burma. Omitting for the present from whence the type forms of vertebrate life were derived, we require to know how it is that some of the identical species of fish are found along the Western ghauts of India and in the Himalayas, but absent from the sub-region of Hindustan ? and how is it we see some genera identical in Ceylon and in the Malay Archipelago or in China, but absent from India and Burma ? The presence of certain Chinese, Malayan, Burmese and Siamese foi-ms in Ceylon and in the Western ghauts, with their absence from the intervening alluvial plains of Hindustan, leads to the supposition already touched npon that, at an antecedent date some connection existed between these earlier geological formations and the more eastern countries. We observe some identical forms in the island of Ceylon and in Java or China, but absent from intervening localities : but does this prove more than that some of those intervening stations have passed away, having been perhaps submerged in the Indian Ocean ? Between Ceylon and the islands of the Malay Archipelago are the Nicobars, not far removed are the Andamans. I have examined some fresh-water fishes (Nuria) from the Nicobars, from ■whence they were brought by Mr. Ball, and find them identical with the species existing in India and Burma. I have personally examined some streams at the Andamans, from which I obtained Ophiocephalus gaclma and Haplochilus panchax, both common to the mainland, and these would seem to point out that a land connection may have existed between these islands and Burma, perhap)S being also extended to Ceylon and the Malabar coast. If this was the route by which fish obtained access from Malaysia to Ceylon, may they not in like manner have been diffused along the hills of Siam and Burma to the Himalayas ? and this would account for such forms as Siliirus, common to these three regions, to the two species of Homalupfera. existing in the Western ghauts and also on the Himalayas. And when we find that the Genera Sihirus, Exostoma, and to a great extent Oreinus are still found thriving along the whole extent of the Himalayas from Afghanistan on one hand to China or even Siam on the other, we perceive that such a view is not contrary to present existing facts. In the alluvial plains of Hindustan there appear to be traces of two piscifaunas, one from the North conjoined with the Ethiopian, and one from the East obtained again from ^lalaysia by way of Burma and Assam. Whether these plains at one period had a wholly Malayan fauna as some suppose I shall not discuss, the late Dr. Stoliczka considered that such was the case, but it became more or less destroyed in those parts which were afiected by the enormous volcanic eruptions, characterized as the trap formation of Central and North-West India. It was after this time that he supposed the African element obtained access to the Hindustan sub-region, and it may have been so, but as already shown it entered (if we take fish as our guide) by way of the Mediterraneo-Persic sub-region, and we still find genera of the latter region (not found in Africa) along the Western ghauts of India {ScajjJdodon) and also at the base of the Himalayas (Eughjiitosternum). Whether this element never extended to any considerable extent to Eastern Bengal or whether the Burmese forms subsequently obtained a preponderance there, or whether as seen in Discognathus lamta, it is still spreading, are problems requiring .solution, but it is quite certain that at the present time the Malayan element is in the majority in the plains of Hindustan, due perhaps to a second wave of fish-life received from the East. Space prevents my entering upon the question from whence these types of genera have originally been derived ? Are they all or only some of Pala?arctic origin ? Have modifications occurred in fish as they have neared the Tropics, by which we could account for all the various families and genera which we now perceive ? I would first remark that Acanthoptertgiax or spiny-rayed forms of fresh-water fishes in India are most numerous in maritime districts, next in the deltas of large rivers, while they decrease as we proceed far inland. The CrPEixiD^ and SiLnRiDj; are the chief elemeuts of the Indian fresh-water INTRODUCTION. xv fish fauna, as out of 69 Genera 35 are CarjJs, 26 Siluroids, and 19 AcantJiopterygians, of whicli last 6 are modified by an amphibious respiration for special tropical requirement ; and of these last forms the family which has the widest distribution is the amphibious OpUocephalidcB, which is likewise the one in which true spines are the least developed. The Acanthopterygian Indian ft-esh-water forms probably had a marine ancestry, several of the genera still having marine species, but not so the Carps. The most important genus of Indian carps is Barhus, possessing about 70 representatives in India, a genus which is likewise found in Europe. We find the largest forms ascending to the colder regions of the hills to deposit their ova : and the species of the genus being of the smallest size in the hot plains where they breed : along with these peculiarities we observe as a rule that similar to the European barbel, we have 4 appendages to the mouth (barbels) in the large forms, 2 in those of medium size, but none in the smaller forms of the plains. It would appear that it is not improbable that many genera of Carps are Palsearctic, their type-progenitors having been derived from a northern ancestry : but there are others, as Romaloptera, Fsilorhynchus, Semiplotm, Catla TkijnnicMhijs, Amblypliarijngodon, Aspidoparia, Bohtee, Chela and their allies, which are no less of Oriental origin, and I hesitate to accept the theory that such are merely modified northern genera. Respecting the scaleless Siluridj;, they as the Acanthopteetgii are perhaps modified marine forms. In them the air-vessel or air-bladder possesses two distinct functional ofiices. In the Acanthoptertgians where this organ is destitute of a pneumatic duct its use (excluding the question of its connection with the internal ear) appears primarily to be a mechanical one, viz., for the purpose of maintaining a required level in the water, and permitting the fish to rise or fall as desired. In the majority of carps (CtfriniDjE) in addition to the foregoing function, a pneumatic tube connects it with the pharynx or upper portion of the alimentary canal, and also a chain of ossicles with the internal ear. In fact, it serves both for the purpo.se of hearing and also for flotation. But in the sheat-fishes (Sildkid^) the power of employing this air-vessel as a float appears to be subservient to that of hearing. Living as they do the life of ground feeders and mostly restricted to muddy localities, this organ is more usefully restricted to acoustic purposes, while the feelers round their mouths permit them to move about with ease and safety, and their organs of hearing to ascertain the vicinity of an enemy or the approach of some incautious prey. In marine forms we meet with this air-vessel having a thick outer fibrous layer and attached to the lower surface of the bodies and transverse processes of some of the anterior vertebrae, while a chain of ossicles connects it to the internal ear. As however we pass inland or towards mountains, a change occurs, the air-vessel being partially or entirely surrounded by bone. This may be effected by a trumpet- shaped extension of the lateral processes of the first or second vertebra: or else by an expansion of the most posterior of the auditory ossicles, but in either case the chain of bones is continued to the internal ear. This being a modification of what we perceive in the Indian marine forms seems to lead to the conclusion that it is through such that the fresh-water species may have been derived. Having briefly adverted to the fresh-water fish and fisheries, it becomes necessary to offer a few remarks upon those of the sea. They not only exist in the open sea and along the coast, but so far as tidal influence extends up large rivers, backwaters and estuaries. Opposite certain places on the coasts of the ]\Iadras Presidency, vast mud banks are present, but they are so fluid as to enable many kinds of fish to find abundance of food there, immunity from disturbance in the surrounding element such as exists in the open sea, and an excellent locality for breeding purposes. Contrary to what obtains in the fresh-water fisheries, there is no paucity of the finny tribes in the sea, but owing to some unfortunate cause, the harvest remains comparatively untouched. But before we condemn the apathy of the native fishermen it will be as well to inquire whether a market exists for the fish were they to capture them? or is the fisherman's occupation directly or indirectly affected by laws and regulations rendering it impossible under present circumstances to carry on his trade in a profitable manner ? If the fisherman has but a limited market for fish when captured, he naturally carries on his industry where he can do so with the least amount of expense and toil, which must be effected by taking the smaller kinds that can be dried with ease, and do not require a large outlay on salt. These smaller fish prefer the vicinity of the shore where they obtain their food, but by destroying the small kinds and the Crustacea, the fisherman is removing from the waters that which decoys the larger and more predaceous ones in. As a result he scares away what should be the natural supply, and to the uneducated eye the amount in the waters appears to have diminished. This does not concern the fisherman so long as his trade supplies his family requirements, neither does it occasion much injury if there is only a local demand and salt is not available for preserving the surplus. I do not intend adverting in this place to the various modes of fishing at present being carried on along the coasts of India and Burma,* but purpose making a few remarks on the fishes of the Indian Ocean. A considerable diflFerence is observable in the regularity with which certain large droves of gregarious fishes as the mackerel {Scomber microlepidotus, p. 260) or the oil sardine {Clupea lonyiceps, p. 637) * See description in "JJeport on Sea Fisheries," 1873. XTi INTRODUCTION. appear, in some years very abundant, in others they are comparatively rare : still it is certain that those which come at particular seasons do so for breeding purposes, full of roe when they arrive, deficient in it prior to their departure, and the young being found in abundance shortly after their arrival, while they were not previously present, can lead us to no other conclusion. The sea fisheries of India ought to be exceedingly valuable as affording an inexhaustible supply of animal food not only to those living in their vicinity, but also inland did means exist to transport the fish either in a fresh or dried state. The distance these fishes can be conveyed fresh inland depends on several causes :* the season may curtail this. In some places the captures are brought on shore in the morning and have to be taken through the sun, but on the other hand if lauded in the evening coolies will not convey them during the dark to distant places. Where water facilities or those by rail exist they may be carried some distance. It is not uncommon to open and clean the fish and rub some salt earth inside which keeps it fresher than it otherwise would be, but small or immature fish decay more rapidly than larger ones. I think it may be safely assumed that fresh fish as a rule cannot be conveyed inland by coolies above ten miles so as to be sanitarily fit for human consumption: but if tliey are opened, cleaned, internally salted, and taken with care, by being shaded as much as possible from the sun's rays, they may be carried considerably further. Seeing that fresh fish are obtainable only by the residents of or near the coasts while the sea is swarming with the finny tribes, we have to inquire are they captui'ed in excess of local demands and if so how are they disposed of ? Dried Jlsh are largely prepared along the coasts, which can be done with the smaller and thinner species, as Equvla (p. 237), Trichiuriis (p. 200), many of the Herrings, the Bombay duck, Harpodon nehereus (p. 605), and numerous others, but for the larger forms this is inappropriate unless in the form of slices cut from them and sun-dried. Sun-dried fish are found wholesale in the Bombay Presidencj, but " whether fish is dried as above in preference to being salted," remarks the Collector of Tanna, " I have been unable to ascertain. It is very probable that it has been resorted to in the place of curing by salt, consequent on the excise duty levied on salt." As we proceed down the coast (I am here speaking from personal observations made in 1872-73), we find the people permitted to gather salt earth for this purpose, and as a consequence they prepare their fish with it in preference to its being simply sun-dried. But ascending the Coromandel coast we are told, " I believe that all the salting much of this so-called cured fish gets is being buried in the sea sand, and thus getting slightly briny " (Collector of TricJdnopoli/). Passing up the Easteim coast we find in Bengal drying in the sun the almost sole means employed for curing fish. Whereas in Burma sun-dried fish is scarcely alluded to in the official reports. This brings us face to face with the question of the reason for this, and whatever may be the cause the following are facts. Wherever salt is expensive the natives have a preference (? due to cost) to sun-dried fish : where salt is cheap,t this mode of preparation is but little employed. Salted fish are cured with (1) monopoly or excised salt, and (2) with salt earth or spontaneous but untaxed salt. In Sind and India the best salt fish is prepared in the proportion of about 1 part of salt to 3 of fish: if salt earth is made use of nearly 3 parts of it to 1 part of fish is required. The salt fish trade of Bombay is almost " exclusively the produce of neighbouring foreign ports," observes the Deputy Commissioner of the Salt Revenue, and the reason is not far to seek, as the duty per maund of .salt was 29 annas in Bombay : while the cost of the whole article in these foreign ports (as Goa, Daumaun, and Diu) is " 2 annas a maund if as much," and where the salt is so cheap more can be afibrded to be used, consequently the foreign article is superior. In the Madras Presidenc}' excised salt is sometimes employed if the better class of salt fish is desired, as for export to Ceylon, to be taken far inland, or for personal consumption. Salt earth or spontaneous salt is largely employed in places, as it is untaxed, at the same time its use for this purpose is declared illegal. But in some localities the dwellers may employ it to prepare fish for their own use, and subsequently there is no law to impede their disposing of their surplus stock. "Of this salt earth," says the Collector of Malabar, "the people dislike it, asserting that it imparts a bitter and unpleasant savour to food and brings on that common complaint in Malabar the itch." In Tanjnre that fish so prepared soon becomes wormy and rotton. But the poor are unable to be too particular as to the taste of their food, a far more important consideration being the coH. Speaking of the cost of salt as it was (it is raised now) a few figures will explain the foregoing. About 82 lbs. weight of salt in Madras cost about 32 annas : with this desci'iption of salt about 246 lbs. of fish could be cured ; omitting wastage and the purchase of the fish we find over 4 maunds, or 328 lbs., costing 32 annas. If untaxed salt earth is employed the cost is from 1/6 to 1/3 of an anna a basket, which is less than 1/4 of an anna for 82 lbs. It requires, however, three times as much * Many civil officers object to doing anything in view of the good of fi.sheries. One Collector at Balasore observed "the people of this district do not salt their fish, they dry it in the sun and eat it when quite putrid. They like it in this way, and there is no rea.son v»hy they should be interfered with." Having persoually visited this locality, 1 may add as a commentary that a native Zemindar's opinion was "chcjUra was made for these people." f Since my investigations were completed the .salt ta.x h.as been equalizea in India, or raised in the Madras Presidency, and still more so in Sind. If my views are correct the returns of 1879 will show a great reduction of salted fish in Sind and a considerable falling off of the article in Jladras. INTRODUCTION. x?n of this to cure fish as it does of the excised salt. If we omit the extra weight of this salt earth we find the cost of 328 lbs. of fish thus prepared costing 1 anna instead of 32 annas, or should twice the weight of this salt to the weight of the fish be used, as is done in the better description, the cost is 2 annas instead of 32, or of a difference of 1600 per cent, in the production. The chief consumers of this article are the poorer classes, and were the tased salt to be employed salt fish would be entirely beyond the reach of those who now purcliase it. Tlio following figures show how the salt-fish trade has flourished on the Western coast of Madras where the people could collect the .salt earth for curing the fish and how it has languished on the Eastern coast where this has not been permitted. The exports show as follows, tlie value being stated in rupees : — • Eastern coast, ? „ ? „ 17,.531. „ 45,137. 5 years ending 1857-58, Western coast, 321,950: „ 1862-63, „ „ 628,624: „ 1867-68, „ „ 1,118,991: „ 1872-73, „ „ 1,780,888: In the last year the return from Travancoi'e not having been received, an average of the five preceding years, or R 133,237, has been added to the total. It appears, in short, that the fisheries are in a very depressed state wherever salt is expensive or the use of the untaxed salt earth prohibited : that they are flourishing where salt is cheap or the use of untaxed salt earth permitted : that monopoly salt is scarcely purchased for the purpose of curing fish eaten by the majority of the consumers, owing to the enormous rise it occasions in the price of the article : that fish is extensively cured with salt earth where permitted, but that such a food is a fruitful cause of disease as the article will not keep for any lengthened period, but it is preferable to the simply sun-dried article : that where the use of salt earth is prohibited, fish curers are driven to dry their fish in the sun, give up their trade, or purchase monopoly salt, and should they do this last they have to keep down the price of the article by reducing the cost of the raw fish and employing a minimum amount of salt.

Vertebrate animals which are, as a rule, exclusively adapted for an aquatic life, and have their extremities modified into fins. Respiring, almost invariably, solely by means of gills :* possessing a heart vsrith only two cavities, and being cold-blooded. They are scaleless, partially or wholly scaled, the scales being sometimes in the form of osseous plates. SYNOPSIS OP SUB-CLASSES. I. Teleostei or Eleutherobranchii. Skeleton osseous. Brain distinct. Skull possessing cranial bones. Vertebrae completely separated, and the posterior extremity of the vertebral column bony, or having bony plates. Branchiffi free, and the water discharged thi-ougb a single aperture on either side, protected by a bony gill-cover or opercle : branchiostegal rays present. A non-contractile bulbus arteriosus, having a pair of valves at its commencement. II. Chondeopteetgii or ELASMOBEiscHii. Skeleton cartilaginous. Brain distinct. Skull vnthout cranial sutures. Gills pouch-like, and attached by their outer edge to the skin, whilst an intervening gill-opening exists between each. No gill-cover. Bulbus arteriosus contractile, and having thi-ee rows of valves at its com- mencement. SYNOPSIS OP ORDERS AMONGST THE TELEOSTEI. I. AcANTHOPTERYGll. A portion of the dorsal, anal, and ventral fins unarticulated, forming spines. f Air- vessel, when present, comjjletely closed, not possessing a pneumatic duct. II. Anacanthini. All the rays of the vertical and ventral fins articulated ; the latter, when present, beiag jugular and thoracic. III. Phtsostomi. All the fin rays articulated, with the exception of the first in the dorsal and pectoral which sometimes are more or less ossified. Ventral fins, when present, abdominal and spineless. Air-vessel, if existing, having a pneumatic duct (except in Sconihresocidw). rV. Loi'HOBR.AxcHii. Fishes possessing a dennal segmental skeleton, with the opercular pieces reduced to a single plate. Gill-openings small. GiUs consisting of small rounded tufts, attached to the bi-anchial arches. Muscular system very slightly developed. Snout produced : mouth terminal, but small. Teeth absent. Air- vessel stated to be destitute of a pneumatic duct. V. Plectognathi. Fishes with the bones of the head completely ossified, whilst those in the remainder of the body are incompletely so : vertebras few. Gill-openings small, situated in front of the pectoral fins. Gdls pectinate. Head generally large. Mouth narrow : the bones of the upper jaw mostly united, sometimes produced into the form of a beak. Teeth in the jaws absent or present. There may be a single soft-rayed dorsal fin, belonging to the caudal portion of the vertebral column, and situated opposite the anal : in some a rudimental spinous dorsal is also present : ventrals when existing, have the form of spines. Skin either smooth, with rough scales, or ossified in the form of plates or spines. Air-vessel destitute of a pneumatic duct. Geographical distribution. The Acanthopterygian Fishes do not exist in any numbers in the inland fresh- waters of India, being mostly confined to either within, or but a short distance removed from tidal • Certain fish as the Lahyrinthici and OpMocephalidce can lire in water even with a bandage fastened ronnd their gills, entirely preventing their use for respiratory purposes, provided they can obtain direct access to atmospheric air. Such a proceeding would however be fatal to the majority of fishes, thus showing that some ibrms possess means of depurating their blood which are not present to all. t There are some genera in which the fins can hardly be said to possess any true spines as amongst the Trachinidm, Aulostoma- tid observed that the effect of keeping living fish in fresh water contained in vessels of different colours, created a tendency to their assninjng the colour of the vessel in which they were kept. In marine forms it has been suggested that the depths of the ocean at which some reside may have an effect upon their colours. FAMILY, I— PERCID^. 7 Pristipoma, Garanx, Osphromenus, &c., vertical bands are found, as a sign that tlie fisli is immatui'e. Lateral longitudinal broad bands are frequently modified, two narrow ones taking the place of a single wider one, as seen in Gheilodipterus, Diagramma, &c. Likewise in stuffed examples, or in those which have been long macerated in spirit, marks which were distinct in the fresh specimen, become more or less obliterated. Irrespective of the foregoing, the period intervening between capture and examination, has a considerable bearing upon their fugitive colours, as well as whether they have been sodden in water, or kept dry by their caj^tors : for instance, if a dark coloured fish is placed in a dry situation, and strips of moist cloth laid over it and kept wet, the portions of the body which have not been allowed to dry will be foimd to be of a lighter tint than those not so treated, and this banded appearance which can be so easily produced is indelible. It is by no means uncommon for the caudal fin to be white in the young, but black in the adult as in Blarjramma nigrum. The foregoing brief remarks on the colours of fishes will explain how it is that the descriptions in this work do not always agree with those of other observers. Such discrepancies indeed often merely mean, that the colours of the same species of fish may differ in different districts. First group — Percina. Form of body oblong.

Scales finely ctenoid, and of moderate size. Ccecal pylori few. Geographical distribution. Mouths of the Nile : fi-om the coasts of Sind throughout the seas of India to the Malay Archipelago, China, and Australia. Uses. Besides being in most places excellent as food, their air-vessels or sounds are di-ied, and appear in commerce as rough isinglass, much of which is exported from India to China, and some to Europe. Cantor observes that this fish " yields isinglass in the Straits, but little is collected, partly on account of the comparative scarcity of the fish, and partly owing to the thinness of the air-vessel. That of a large sized fish when di-ied weighs uj)wards of one ounce." SYNOPSIS OF INDIVIDUAL SPECIES.* 1. Lates calearifer D 7— S/xx-Taj ^- 8-o> ^- 1- ^^- Colour greyish.

An excellent method is to begin with that form which is most typical : a second plan is to commence with those having the greatest affinity to the preceding Genus and finish with those closely allied to the following one, in which case the most ty]3ical forms are in the middle: the third and least scien- tific is what I propose adopting in order to facilitate reference, it is to place first those possessing the largest number of spines, rays and scales, and continuing this plan throughout the Genus. Colour will not be adopted for reasons advanced under the next Genus.

Air vessel — thin, but furnishes a good isinglass. Colours — grey, with a dash of green along the back, and silvery on the abdomen : during the monsoon time it has a tinge of purple. The immatm-e are usually darker than the adults. Having examined Bloch's typical specimen stiU at Berlin, I find that it has as he states D. 7/J„. Deformities in this fish are by no means rare. In one case the last few dorsal rays were deflected to the left side of the free portion of the tail, and had there become continuous at their bases with the anal spines, which were likewise inserted along the same portion of the fish, whilst the anal rays were in their natm-al position. It is very remarkable how in fishes which have died and stiffened with their mouths open, and the opercles and branchial rays distended, the appearance of the head becomes much changed, whilst it is difiicult, or impos- sible to subsequently bring them back to their normal shape. Thus the profile of the head becomes more horizontal, whilst the posterior extremity of the maxilla does not reach so far back as when the mouth had been natui-ally closed. Hahitat. — Seas, backwaters, and mouths of tidal rivers in the East, up which last it often ascends long distances to prey upon its weaker neighbours.

" Cavolini and Cuvier have, after repeated examinations, described the smooth Serranus (S. cahrilla), and some other species of this genus as true hermaphrodites, one portion of each lobe of I'oe consisting of true ova, the other part ha-ving all the appearance of a perfect milt, and both advancing to maturity simultaneously. A structure of a different kind which must be considered as accidental, has been observed by others in the perch, mackerel, carp, cod, whiting, and sole. Tliis occasional malformation, to speak in a popular phrase, consists of a lobe of hard female roe on one side, and of soft male roe on the other side of the same fish. "J The colour of these fishes, which varies so extensively ip the same species, can hardly be accepted as a trustworthy guide for grouping. The form of the preopercle is not invariably identical in every specimen of the same species, or even on the opposite sides of a fish : whilst a spine is occasionally present at its angle in the immature, becoming more or less absorbed in the adult. The sub- and inter-opercles may be serrated or smooth in the same species as observed in Serramis boenach. The fins also alter with age, owing to the spines not increasing in length so rapidly as the rays, consequently they may be comparatively shorter in the adult than in the young. Even the rays in the mature fish are found less in their proportionate height to the entire lencrth of the specimen, than they are in the immatiire. The same thing occurs in respect to the anal spines, the second is sometimes the longest in the immature but becomes shorter than the third in the mature, and this appears to be most frequent when the second spine is the strongest, augmenting in thickness whilst the third increases in length. Occasionally there is an excess of one spine and a deficiency of a ray in the dorsal fin, the first of the rays having apparently taken on a spinous character, as is seen more distinctly in some of the Spaeidj;. The nimibers of rows of scales is very important amongst these fishes, as so ably pointed out by Bleeker, and many a mistake in identification would have been saved, had his plan been adopted, which is to give the numbers of transverse rows going to the lateral-line from both above and below. As an example I would point to the Serranus Sonnerati, so easily distinguished when this plan is followed, but apparently so diflioult where it is not attended to. Geographical distribution. — The seas of temperate and tropical regions. The members of this genus in India may be considered as entirely marine, a few, it is true, ascend rivers not for breeding but predaceous purposes, restricting their range, however, to within tidal influence. * Fishes of this genus are termed CuUawah, Tarn. f In the Proc.

Preopercle serrated along its vertical edge, and with from two to four strong denticulations at its angle which is rather produced, especially in the adult : sub- and inter-opercles entire. Opercular spines distinct, the central one the most developed. In the fry a distinct sprue exists at the angle of the preopercle. Teeth — one or two rather small canines on both sides of the symphysis in either jaw, those in the upper the larger : outer row of teeth in maxilla, and inner in the mandible larger than the vrllifomi bands. Fins — dorsal spines of moderate strength, the third to the fifth the longest, equal to the distance between the hind edge of the orbit and the upper opercular spine, and nearly as high as the rays : pectoral and ventral of about the same size, and equal to the postorbital length of the head : second anal spine the strongest and nearly as long as the third, which equals one and a third diameters of the orbit in length. Soft portions of dorsal and anal fins somewhat rounded : caudal cut square in the adult, but rather rounded in the young. Scales — ctenoid. Colours — reddish-grey, becoming lighter on the abdomen : numerous oblique nan-ow brown (blue ?) bands of varying length, and usually somewhat sinuous above the lateral- line not following the course of the scales, whilst they are more or less horizontal below it : dots and yellow lines on the head : fins rather dark, and stained at their edges. I place this sjjecies as iS'. undulosus, in accordance with Bleeker's observations. There is no doubt but that it is identical with S. lineatus C.V., the type specimen of which (a skin) exists in Paris. Amongst Sir Walter Elliot's drawings is one of this fish, termed Seela panni, October, 1848. Habitat. — Seas of India to the Malay Archipelago and China.

Fins — dorsal spines of moderate strength, the fourth the longest, from whence they slightly decrease to the last, which is not so high as the fii'st ray : soft portion of the dorsal and anal fins angularly rounded : pectoral a little longer than the ventral and equal to the length of the head behind the middle of the eye : second anal spine strongest and sHghtly the longest : caudal obtusely rounded. Scales — ctenoid. Colours — reddish brown with a light reticulation causing the body, and also the pectoral, soft dorsal, and caudal fins to be covered with hexagonal, or sometimes rounded markings. In some specimens the dark blotches become more confluent, the light reticulations being indistinct. Although Bloch 's figtu-e (t. 329) more resembles S. hexagonatus than the species under which I here place ity'jaj reason for doing so is that Professor Peters has shown me the typo specimen which unquestionably belongs to this species. Serranus ajlindrkus, Giinther, Catal. i, p. 151, in some respects very closely resembles this species, its scales are L. r. VV"' L. tr. 13/, the diameter of its eye 4§ in the length of the head, and 1 diameter from the end of the snout. Although the body is more elongated, it is wider than normal. I almost think that it will tm-n out to be a variety of this species. In Cuv. & Val. it is suggested that Trachinus Adscensionis, Osbeck, ii, p. 96 belongs to this species, he observes " the hodg is somewhat compressed and not quite round." Hahitat. — Red Sea, East coast of Africa, seas of India, Malay Archipelago to the Pacific. The specimen figured was taken at the Andaman Islands and is a little over 8 inches in length, 7.

Length of head 3/10 to 2/7, of caudal 1/6, height of body nearly 1/4 of the total length. Eyes — diameter from 2/9 to 1/5 of the length of head, rather above 1 diameter "from the end of snout, and 1 apart. The maxilla, wliich is rather wide posteriorly, reaches (in the young) to below the last thii-d of the orbit, and in the adult to beneath its hind edge. Preopercle rounded, mth "its vertical border strongly but pretty evenly serrated, whilst its angle is a little produced and has about eight coarse denticulations. Opcrcle -n-ith the central spine well developed. Teeth — small canines in either jaw : the outer row in the maxilla, and the inner in the mandible larger than the villiform bands. Fins^ioran^ spines of moderate strength : they increase to the third, which equals half the length of the head, and is one half longer than the rays : from thence they decrease, but the last is nearly as long as the rays ; the soft portions of the dorsal and anal are somewhat angular : pectorals longer than the ventrals and equal to the length of the head from behind the middle of the orbit: second anal spine strongest but not so long as the third, which is neai-ly one thii-d of the length of the head : caudal cut square but with FAMILY, I— PERCID^. 15 rounded angles. Scales — ctenoid. Colrmrs — deep gi'ey, with round black spots somewliat distantly placed on the head, pectoral, and ventral fins : oval spots, having their longest diameter vertical, exist in the anterior half of the body, becoming more like short thick sinuous lines on the last half. A black edge along the top of the spinous dorsal, and some cloudy interspinous marks : the soft dorsal, anal, and caudal "with a black edge and white margin. Bleeker, in his excellent revision of the Epinephelini, observes that lie possesses a beautiful series of specimens of this species showing the successive transitions in colonr, which certainly varies very considerably. The young (maculatus) , according to Bloch's figure, appears to have a light ground colour with a dark band over the head : a secoud, from the second to the fifth dorsal spine, passing downwards, encloses the pectoral, and ventral fins : a third from the soft dorsal passes down to the whole of the anal : one more exists over the free portion of the tail, and two on the caudal frn ; a dark horizontal band appears to connect the others along the middle of the body. The specimen figured (7 inches in length) fi'om the Andaman Islands agrees with Eoier's S. longispinis. The type specimens of S. Gaimardi in the Paris Museum have a much higher body comparatively, whilst the longest dorsal spine scarcely exceeds the length of the rays. Habitat.— 'Ea.st coast of Africa, seas of India, Andamans to the Malay Archipelago, and China. 8. Serranus flavo-cseruleus, Plate III, fig. 1. Holocentms flavo-cceruletis, Lacep. iv, pp. 331, 3ti7.

Scales — ctenoid on the body, thickly covering the snout, pre- and sub-orbitals, likewise the posterior half of the maxilla : about 18 rows between the lateral-line and the sixth dorsal spine : those on the chest and abdomen very small, about 65 rows between the lateral-line and the median line of the abdomen. Colours — head and body of a deep purplish blue : free portion of the tail and all the fins gamboge yellow: some yellow on the snout, maxilla, chest, and opercular spines : an indistinct darkish band along the base of the spinous and first third of the rayed portion of the dorsal fin : ventral, and caudal with fine black tips. Jerdon says (M. J. L. and Sc. 1851), p. 129, " Serranus flavo-jmrpureus, Bennett. This very beautiful fish is very rare at Madi-as. I never saw but one specimen. I procui-ed the very young at the Sacrifice rocks on the Malabar Coast, it looked like a living sapphire." Bennett observes that it is scarce on the southern coast of Ceylon, in the course of two years having met but with one specimen. Habitat. — Seas of India to the West coast of Africa. The specimen figured was from the Andaman islands, and is nearly 10|^ inches in length. 9. Serranus fasciatus, Plate III, fig. 2. Perca faseiata, Forsk. p. 40 ; Gmel. Linn. p. 1316.

Length of head from 3/10 to 2/7, of caudal 1/6, height of body 2/7 to 1/4 of the total length. %es— diameter 1/4 to 2/9 of the length of head, 1 diameter from end of snout, and 3/4 of a diameter apart. The maxilla extends to below the hind edge of the orbit. Preopercle rather strongly serrated along its vertical border, rather more coarsely so at its angle, above "which it is somewhat emarginate, its lower limb entire. Sub- and inter-opercles either entire, or with a very few fine serrations. Central opercular spine the most developed. Teeth canines in both jaws, the outer row of teeth in the maxilla, and the imier in the mandible larger than the N-illiform bands. Fins — dorsal spines from the third of about the same length, but not so high as the rays, the last are ecpial to two-fifths of the height of the body : pectoral slightly longer than the ventral, and equal to the length of the head behind the middle of the eye : ventral not reaching the vent : second anal spine the strongest, a little longer than the third which nearly equals the last in the dorsal fin : caudal rounded. Scales — on the body ctenoid : from 12 to 14 rows between the lateral-line and the base of the sixth dorsal spine. Colours — in (S'. fasciatus reddish or yellowish, with five dark vertical bands, a fine black edge along the whole of the dorsal fin. In S. oceanicus the cross bands may be absent. In S. margiualis brownish or yello-svish, the dorsal, and caudal fins being black edged. In S. variolosus brownish, with spots over the head, body, and soft dorsal fins. Sir J. Richardson directed attention to the S. tsiriiiienara of the ' Fauna Japonica ' being distinguished from this fish, owing to its possessing a row of five or six irregular whitish and indistinct spots on the flanks. Bleeker observes that these spots are in two rows above, and below the lateral-line, irrespective of which on comparing specimens of the two species of the same length together, he found that in the 8. tsirimenara the body is less rounded, the head more pointed, and the rows of scales above and below the lateral line are •H-o-i+a • .

The maxilla reaches to nearly or quite below the hind edge of the orbit. Vertical limb of preopercle slightly emarginate, with the angle rounded, the whole being finely serrated, most coarsely so at its angle : sub- and inter-opercles entire. In small specimens, e. g. 2i inches long, tliis species has a spine at its preopercular ano-le, whicli becomes absorbed as ago advances : in some specimens some rather large denticulations are seen at this place, due to this absorption not having been so rapid as usual. Teeth, — canines in both jaws, the outer row in the maxilla, and the imier in the mandible, rather larger than the villiform bauds. Fins — dorsal spines from the third continue of about the same length, from 2/5 to 1/3 of the height of the body : the pectoral longer than the venti'al, and equalling the length of the head behind the middle of the orbit : second anal spine the strongest, equal to or not quite so long as the third : caudal roiinded. Scales — ctenoid, about 14 rows between the lateral-line and the base of the sixth dorsal spine. Colours — greyish olive, darkest along the back. Body and head covered with irregxilarly sized pearly-white spots, whilst a black line exists on the maxilla. Fins dark gi'ey, externally nearly black, the pectoral, ventral, soft dorsal, and anal with a narrow white border : the whole of the dorsal fin white spotted. The colours vary much with age. Habitat. — Red Sea, East coast of Africa, seas of India to the Malay Archipelago. The specimen figured is 6 inches long. 11. Serranus diacanthus, Plate III, fig. 4.

Eijes— diameter 1/4 to 2/9 of the length of head, 1 diameter from the end of snout, and also apart. The maxilla reaches to below the hind edge of the orbit: lower jaw the longer. Vertical limb of preopercle strongly serrated, with two or three coarse teeth at its angle, its lower limb entire : sub- and inter-opercles entire. Three spines on the opercle, the centre of which is the largest. In a young specimen (3 inches long) the serratures at the angle of the preopercle are scarcely enlarged, but at 3| inches in length they commence to become coarser than those along the vertical border. Teeth — one or two canines on either side of each jaw, those in the man- dible being the smaller : outer row in the upper jaw rather stronger than the viUiform bands ; inner row in the mandible a little the largest. Fins — dorsal spines rather weak, and being of nearly equal length from the third, which equals two-fifths of the length of the head : pectoral rather longer than the ventral : second anal spine rather longer than the third, and eqiwltothe_second of the dorsal fin : caudal rounded. Scales — ctenoid on body, and in about 20 rows between the tirst dorsal iTpine aiid'tEe'latenil-line. Ccecal 'fylori — eleven long ones. Colours — brownish, with a tinge of pink on the back, becoming rose-coloured on the abdomen. Six dark vertical bauds, the first crossing the head : the second from the fourth to the sixth dorsal spines passing over the pectoral to the base of the anal : the remaining three take the same direction, the last crossing the free portion of the tail. A dark band passes from the orbit to the angle of the preopercle. Fins darkest at their margins. Occasionally the bands are continued on to the dorsal fin. A specimen in the British Museum has a white edge to the dorsal, caudal, and anal fins. Dr. Jerdon, M. J. L. & Science, 1851, p. 129, observes of S. nelidosus, Cuv. & Val. "I procured one specimen of this at Madras and one at Tellicherry." The latter, a copy of the figure of which exists amongst Sir Walter Elliot's drawings, is the fish above described.

The maxilla reaches to below the hind edge of the orbit. Vertical limb of preopercle rather coarsely serrated, with two large spinous teeth at its angle, the inferior of which is directed somewhat downwards. Opercular spmes well developed. Teeth — small canines in both jaws, the inner row of teeth in the lower jaw, and outer one in the maxilla, longer than the villiform bands. Fins — dorsal spines moderately strong, increasing in length to the fourth and fifth, which equal nearly half the length of the head, but are not quite so high as the rays : soft portion of fin, also of the anal, and the caudal rounded : pectoral as long as the head excluding the snout : second anal spine stronger but not quite so long as the third. Scales — ctenoid. Colours — brownish, with about six vertical darker bands, about as wide as the ground colour : a few irregular dark spots about the body : dorsal, caudal, and anal yellow, with numerous round black spots, those at the hind edge of the caudal almost forming a black band with a white outer edge : pectoral and ventral greyish. I examined two specimens of this species from Japan in the Berlin Museum, the largest being about 7 inches in length. This species I have not captured in India, the form I termed S. se.rfasciatus being tho D 18 ACANTHOPTERTGII.

The maxilla reaches to a little beyond the vertical from the hind edge of the orbit. Preopercle with its vertical edge having a shallow emargination above the angle, and finely serrated, becoming somewhat coarsely so at the angle : its lower edge, and also the sub- and inter-opercles entire. Opercle with the central spine most distinct. In tlie fry there is a well-developed spine at the angle of the preopercle. Teeth— a smaU canine on either side of upper jaw, and a still smaller one in the lower jaw : no enlarged row m the upper jaw, but the iimer row in the mandible, especially posteriorly, much the largest. J'/yts— dorsal spines* not so high as the rays, its soft portion and also that of the anal rounded : pectoral longer than the ventral, and equal to^the postorbital portion of the head : second anal spine stronger but shorter than the third : caudal rounded. ,S'cn?es— cycloid, but usually with raised circular lines upon them, especially in the forepart of the body, about 15 rows between the 6th dorsal spine and the lateral-line. Ccecal-pylori—yerj short, consequently in tl'ie young appear almost like a gland. Colours— yavj with age, the very young being of a fine citron or sulphur oTound-colour, having irregular vertical bands and markings, which become more distinct as the age of the fish advances. About to a foot or even eighteen inches in length, the ground colour continues to be bright yellow, with five vertical, blackish-blue bands, the first passing from the orbit downwards over the preopercle ; the second from the nape to the opercle joins the first baud in its posterior margin, and coalesces with the third behind or above the pectoral fin : the third proceeding from the bases of seven dorsal spines (3-lU), passes dowiwards to the abdomen : the fourth passes from the fifth to the last dorsal ray, and descends to the base of the anal fin : the last surrounds the free portion of the tail, j^i/is— yeUow with black spots or blotches, formmg confluent bars at their bases, which on the pectoral are disposed in three or four undulating arched bands. In the adult the black bands disappear, the ground colour- becomes greyish-brown, the whole being reticulated with greyish-black lines. The fins retain most of their original yellow colour but the amount of the black decreases. Amongst Sir Walter Elliot's drawings are two of the adult of this fish, termed Panni min and Pilli pumii, having a remark attached "younger with transverse bars." _ i j i ■ In " Fishes of Malabar," I considered, as Cantor had previously done, that S. horridus was the adult ot this species.

Length of head 3i to Sf, of caudal 1/5 to 1/6, height of body 2/7 to 1/4 of the total length. Eijes— diameter 1/5 to 1/6 of length of head, 1 to U diameters from the end of snout, and the same apart. Interorbital space fiat : the prffimaxillary reaching to opp'osite the front edges of the orbit. The maxilla extends to below the posterior edges of the orbit, or even behind it in large specimens. Vertical limb of preopercle slightly emarginate, finely serrated, becoming more coarsely so at its rather square angle, where there exist from four to seven coarse teeth, its lower margin entire, as are also the sub- and inter-opercles, occasionaUy there are two or tkree serrations on the inter-opercle. Opercle with three spines, the central one being the longest. The fiy has no spine at the angle of the preopercle. Teeth— one or two canines in either jaw, those m the upper usually the lono-er • the outer row of teeth in the upper jaw, and the ianer in the lower, are the largest. i^/«s— the dorsal spiSes from the third are of about the same height, and equal to one-half the length of the post-orbital portion of the head, but not so high as the rays : the pectoral is longer than the ventral, and about equal the post-orbital portion of the head indength, soft portions of dorsal and anal fins rounded : the second anal spine in most estuary specimens equal the length of the third, but in marine ones it is often slightly shorter : caudal rounded. Scales- ctenoid, and in about 15 rows between the 6th dorsal spine and the lateral line. Cecal pylori— bom 50 to 60, but two or more open into a single basal tube. Co?oi«-«— brownish, fading to grey or dirty wlute on the abdomen : the whole of the fish, even over to the branchiostegal rays covered with bright yellow or orange spots, which often become brown after death : three large blotches on the inter-opercle appear to be present m all varieties of this fish In the S. Malabaricus Bloch, some brown spots are often dui-iug life intermingled with the orange ones, and it is vertically banded usually as follows ; one passes from the first four dorsal spines to the pectoral fin : another from between the second and ninth to the abdomen : two more descend fi-om the soft dorsal fin, and a fifth encircles the free portion of the tail : pectoral reddish spotted with yellow, sometimes the caudal, pectoral and ventral fins are unspotted but marked with darker shades, or the bands are contmued on to them. This variety is the commonest, mostly marine, and the bands are unusually well marked m the young. In the variety S. hontoo, the bands when present bifurcate inferiorly, and the spots are all black ; this is a marme and the rarest form, never appearmg to attain to a large size. In the variety S. coioides, H. B. = S. suillm, C. V. the bands are absent, or else indistinctly visible ; this is mostly taken in estuaries or large rivers, as the Hooghly at Calcutta. • j. >> i? i i. lo'? Russell observed that the plate 128 (S. hontoo) may perhaps "be merely a variety ot plate U/ (S coioides) Hamilton Buchanan, p. 82, remarked of his coioides, " this fish agrees so well with the description of 'the medinawa hontoo of Dr. Russell (Indian Fishes, vol. ii, no. 128) that I do not think them difierent species," p. 82. Cuvier considered Russell's species distinct : Playfair, " Fishes of Zanzibar," doubted li they might not be identical. , « ^ ^ • i ii r • -4.1 Russell records one taken at Vizagapatam in January 178b, which measured 7 feet m length, 5 m girtii, and weio-hed upwards of three hundred pounds.

Colours — body reddish-bro-wn, with six or seven broad darker vertical cross bands : head and first portion of the body, as well as the fi-ee portion of the tail, with some small well-marked spots : dorsal and anal yellow, and likewise spotted : ventral grey. It has been suggested that Perca scptemfasclate, Thunb. (Nov. Ac. Stock. 1793, pi. i, f. 1) is this species; the specimen figured was obtained in Japan, and Professor Peters was good enough to show me one of Temm. and Schlegel's types of Plectropoma snsuld from Japan, the two being compared appeared to entirely agree, whereas the P. susul-i is evidently distinct from the V- 1/5.

Vertical limb of preopercle rather convex, and a little emarginate above its angle in the adult but not in the young, its upper two-thirds finely serrated, more coarsely so at its angle, where the serrations are rather irregularly disposed : lower limb entire, as are also the sub- and inter-opercles (in one specimen both sub- and inter-opercles are serrated). Three strong opercular spines, the central being the most developed. Teeth — one or two strong canines or either side of both jaws, the upper being generally somewhat the larger : the outer row in the upper jaw, and the inner in the lower, being larger than the others. Fins — dorsal spines from the third are of about the same length, the longest being 3/4 tiie length of the longest ray : soft portions of the dorsal and anal obtusely angular : second anal spine the strongest, equal in length to the third in the adult or even longer in the young : caudal rounded. Scales — ctenoid, covering the forehead and preorbital but none on maxilla. Colours — when alive very brilliant, but fading after death. Generally yellowish-brown, snout pale blue, lips and throat spotted with a deeper blue, whilst about five fillets of the same colour diverge from the orbit and cross the opercles and branchial membranes. Blue and rather tortuous horizontal lines pass from the head towards the tail below the kiteral line, whilst above it are about eight more dii-ected backwards, upwards, and continued on to the dorsal fin throughout its whole extent ; these blue lines are likewise continued on to the other fins, except (occasionally on) the ventrals, which however become nearly black at their extremities. Some blue spots exist anterior to the base of the ventral fin (male), also occasionally on the jaws. There are three figures of this fish amongst Sir W. Elliot's drawings, termed Nama panni, Neela panni, and Panaina JniUawaie : one was captured at Waltair, March 24th, 1853. 24 ACANTHOPTERYGII.

Madagascar, p. 20), identical -n-ith Ejjinephelas PoUeni, Bleeker, 1. c. p. 19 : the caudal is cut nearly square instead of being rounded as in iS'. hoenadc. A beautiful specimen exists in the Paris Museum received from M. Lienard, of the Maui'itius, but the description I am unable to recognise in his papers.

His especial reason for considering it a new species appears to be the character o£ the scales which were small and ctenoid. Those on the sides being slightly keeled, forming about 20 horizontal rows. This aijpearance is more seen in some specimens than in others, and is not peculiar to this species. In 1867, a Serranus diacanthxis about 18^ inches long, which was not quite fresh, was brought to me at Madras. I had it preserved a.s a skin and dried rather too rapidly, the result being that all the rows of scales on the body show a well developed keel. I have also seen this appearance caused in fish which have been immersed, from the first, in spirit of too great a strength. FAMILY, I— PERCID^. 27 Lahrus pundaius, Lacep. iii, p. 431, pi. 17, f. 2.

Oeographical distribution. — From the Red Sea and East coast of Africa through the seas of India, the Malay Archipelago, and to the Pacific. Uses. — As a rule all these fishes are good as food, though some are insipid : a few attain a large size. They are extensively salted and dried in many localities. Amongst the Lutiani exist variations which require notice. Thus in some, when immatiu-e (as observed in a few Serrani), a spine exists at the angle of the preopercle : as age advances it is gi'adually absorbed, altliough occasionally in the adult coarse serrations may indicate its prior existence. Instead of one there may be several spinate denticulations at this spot in the fry, which also disappear, as in the case of the single spine. The interopercular knob, in those species which possess one (^Genus Biacope, Cuv. and Val., or Genyoroge, Cantor.) appears in two distinct modes — either as well formed from birth with a notch in the vertical border of the preopercle — or else the knob is gradually formed, and as it increases in size it presses against the vertical border of the preopercle causing absorption at the spot above it and thus creates a notch. Respecting the dorsal spines, it has been remarked of the Serrani that one ray may occasionally assume the form of a spine, thus changing the specific number (by the addition of one spine and the diminution of one ray) but this seems to be rather rare amongst the Indian Lutiani in which, although the spines may bo increased, the rays are not usually diminished in number : an increase in the number of the rays is, however, of more frequent occurrence than in the spines. In colouring there is one subject that requires fiirther examination, and that is the lateral blotch : in those species in which it is present, it is sometimes most decided in the young, but whether it frequently exists in some specimens and is absent in others remains to be solved. That it disappears if the fresh specimen is left soaking in water is evident : that it sometimes is all but lost in those kept in spirit is also apparent, but the similarity of Lutianus inarginatus without a lateral blotch to specimens in which it is present is so gi'eat, that I cannot separate them into distinct species ; the same fact has been observed by Bleeker, in L. Bengalensis and Amboinensis. It is not a little remarkable that this mark is of a deep black colour on the Malabar coast, in L. marginatus ; but much less apparent in specimens captured on the Coromandel coast, where also those of an identical size without any such blotch are numerous. Age then cannot be the sole cause, which may be sought for in locality and sex (provided they are the same species). SYNOPSIS OF SPECIES. 1. Lutianus Sebce, D.

Both the vertical and horizontal limbs of the preopei-cle serrated, the foi-mer having a deep emargination in the adult to receive a well developed iuteropercular knob which in the young is not so distinct. Teeth — canines m the premaxillaries, an outer I'Ow of curved canine-lLke teeth in the jaws : villiform in a ^-shape in the vomer, and in a band on the palate, none on the tongue. Fins — third dorsal spine the longest, rather above half the length of the head, from thence they decrease to the last but one : soft portion of the fin and also of the anal, elevated and pointed, much higher than long at its base. Pectoral nearly as long as the head. Third anal spine somewhat the longest and nearly equal to the post-orbital portion of the head. Scales — in oblique rows above the lateral-line and horizontal ones below it : superiorly they reach to above the hind edge of the orbit : caudal emarginate. Colours — reddish, a black band passes from before the dorsal fin, through the eye to the snout : a second from the second to the sixth dorsal spines to the ventral fin : a third from the soft dorsal, curving downwards to the lower half of the caudal : ventrals and lower half of anal black. Bleeker observes that he possesses a very young specimen (35'" long) in which the soft dorsal and anal are more romided, and in colour it appears as if it were brownish, traversed by two narrow white bands.

Eijes — diameter 1/4 of length of head, 1^ diameters from the end of snoiit, and 3/4 of a diameter apart. Form of the body not so compressed as in L. erythropterus, its width being equal to two-fifths its height : a slight concavity over the orbits : lower jaw the longer : height of preorbital equals 4/5 of diameter of eye. The maxilla reaches to below the first third of the orbit. Preopercle with a very shallow emargination on its vertical border which is finely serrated ; at its angle the sen-ations become larger, whilst four or five of diminished size exist along the posterior half of the lower limb. Teeth — two or three rather strong curved canines on either side of the premaxUlaries ; an outer row of cm'ved conical canine-like teeth in either jaw : villiform ones in a ^-shape on the vomer, a broad band on the palatines, none on the tongue. Fins — dorsal spines moderately strong, from the third they are of about equal length but shorter than the rays, the third spine equals about one-third of the length of the head ; the last spine equals one diameter of the orbit : the seventh or eighth ray is the longest, and equals four-fifths of the extent of the base of the fin, soft dorsal and anal both somewhat angularly rounded and of the same height. Pectoral longer than the ventral, almost as long as the head and reaching to above the anal spines : second and third anal spines of about equal strength, the latter slightly the longer and nearly equalling the thu'd of the dorsal fin : the foui-th ray is the longest, slightly exceeding the highest in the dorsal fin : caudal slightly emarginate. Scales — rows not tortuous, those above the lateral-line oblique, as are also those below it above the level of the lower edge of the orbit, below which they are horizontal : two broad rows over the nape, and eight across the cheek : they extend along the back as far as to a level with the hind edge of the eye. Colours — having a roseate tinge in life with narrow oblique yellow streaks above the lateral-line, and longitudinal ones below it : a longitudinal violet-purple band passes from behind the eye along the base of the dorsal fin opposite the end of which it is interrupted by a light band over the commencement of the tail, subsequently it reappears in a lighter form across the middle of the free portion of the taU. Fins reddish, the dorsal and caudal with a fine black edge : anal spines dark grey, those of ventrals white. Schneider's type specimen is stUl in good preservation at Berlin, and identical with the one figured which I took (a little over 8 inches in length) off the 'Meckran coast. It is closely allied to L. erythropterus ; but the dorsal spines are much lower, the eye and the colours &c. differ. Valenciennes remarks that as Bloch received his specimen from the Coromandel coast of India it is difficult to perceive why Schneider gave to it the term Malabaricus. The reason is that Tranquebar (from whence it came) and the southern portions of the Coromandel coast were then termed ' Malabar,' and to this day the natives of Madras call those residing to the south ' Malabars.' Habitat. — Coasts of Sind and India. 32 ACAIs^^THOPTERYGII. 3. Lutianus erythropterus, Plate X, figs. 1 (j-omig), 2 (adult). Lutianus erytliroj-'terus, Bl. t. 249 ; Bl. Schn. p. 325 (not Bleeker).

Length of head 3f to 3|, of caudal 1/5 to 1/6, height of body fi-om_2| to 3^ in the total length. Eyes— diameter 1/5 to 1/6 of the length of the head in the adult, but much larger in the young,* Ii to 2 diameters from end of snout, and Ij to Ii apart. Body compressed, dorsal profile more convex than that of the abdomen, and slightly concave about the orbit. The maxilla, in the adult, scarcely reaches to below the front edge of the orbit. Preopercle with a very shallow emargination on its vertical limb which is finely and evenly serrated to above its angle where the serrations become coarser, they extend for a short distance along its horizontal border : sometimes a very small interopercular knob exists. Teeth — one or two canines on either side of the premaxiUary, an outer row of cui'ved canine-like teeth in either jaw, villifonn ones in a triangular patch on the vomer, and in a rather naiTOW band on the palatines : none on the tongue. Fins — dorsal spines of moderate strength increasing in length to the fom-th which equals two-fifths to one-tliii-d of the height of the body, from it to the last they are slightly lower and sub-equal in length, the soft portion of the fin more angular in the adult than in the young, the seventh to the tenth rays being the highest, half as long again as the fourth spine, and their height equalling the length of the base of the soft portion of the fin. Pectoral reaching as far as the ventral, and equalling the length of the head behind the posterior nostril : ventral spine as long as the fourth of the dorsal fin : second anal spine somewhat the strongest, but not quite so long as the third which equals the third of the dorsal fin : caudal slightly emarginate or cut square in the young. Scales — in somewhat tortuous rows going in a dii'ection upwards and backwards, they extend over the base of the dorsal fin reaching highest on the I'ays, they are equally developed over the bases of the caudal and anal. Colours — crimson with orange reflections : a broad blackish band passes fi-om the eye to the commencement of the dorsal spines, and is sometimes slightly apparent along the whole base of the fin : eight to twelve narrow and nearly horizontal black lines exist below the lateral-line, and several more above it, some being the continuations of those which commence below the lateral-line. A black band crosses the back over the fi-ee portion of the tail, having a white one before it, and a narrow pink one posterior to it. Pectoral flesh-coloured : ventral either black or stained black in its outer half or two-thirds : dorsal dark grey in some specimens with a nearly black base and a black edge : caudal pink with a narrow black border : anal darkest anteriorly. Li adults (12 inches) the black lines disappear, and each row of scales has a golden line : a trace exists of the band from the eye to the dorsal fin : whilst that over the free portion of the tail is somewhat indistinct. Amongst Bloch's typical collection in the Berlin Museum, Professor Peters showed me two of this species, one being young with the distinct colours of the annularis; the other more adult. Bleeker considers the erythrojyterus of Bloch to be identical with L. lineolatus, and certainly the body and fins in the figui-e appear more to resemble that species than the present : the head, (especially the eyes,) difi'ers considerably from the lineolatus. The type specimens have their original names upon them. Although Ruppell's figure of Biacope erythrina very closely resembles an adult of this species, he states it to have only 10 dorsal spines. Col. Playfair obtained a " fine specimen" now in the British llusenm, termed erythrinus, which is the adult of this species, but it has 11 dorsal spines, it is nearly 18 inches long, and the eye is 5| in the length of the head. In the Berlin Museum is a fine specim.en (21 inches in length) of Biacope sanguinea, (Ehren.) Cuv. and * The following are the measurements as to the size of the eye compared with the length of the head in specimens of various ages: At 6 inches in length, 3J in the length of the head. „ "a )j )' j» ^2 »i " '» '» „ i '■ j» ,, ,1 'Ji ij )» )i n „ lo ,, ,, ,, 2 ,, » J, ,1 )) 21 „ „ „ 1/6 ,, ,, „ ,, FAMILY, I— PERCID^. 33 Val. type of the species. It appears identical with this fish. Length of head y, of caudal -}, height of body nearly J of the total length. Eyes — diameter 5| in the length of the head, 2 diameters from end of snout, and li apart. Fins — fourth and fifth dorsal spines of equal height, and 2f in the length of the head. The type specimen of Mesoprion rubelius, C. V., in the Paris Museum is a sMn ft-om Pondicherry of this species, its scales are L. r. 67, L. tr. 12/25.

Eyes — diameter 1/4 of length of head, 1^ diameters fi'om end of snout, and nearly 1 apart. Body compressed, profile above the orbit some- what concave : the distance between the eye and the upper edge of the maxilla equals a little more than one diameter of the orbit. The maxilla extends to beneath the front edge of the orbit. Vertical limb of preoperele having a shallow emargination, the whole being finely serrated superiorly, but more coarsely so at its angle : lower limb finely serrated in its anterior half. A small interopercular knob. Teetli — a pair of moderately sized, curved canines in the premaxillai-ies, and having two smaller intermediate ones : an outer row of curved, canine- like teeth in both jaws, largest in the mandible, especially about its centre : none on the tongue. Villiibrm ones in a A-form on the vomer, and in a band on the palatines. Fins — dorsal spines of moderate strength, the fourth and fifth the longest, and equal to 3j in the height of the body, they gradually decrease to the last, which is only two-thirds as long as the fourth : the soft portion of the dorsal angular, and one-fifth higher than its base is long. Pectoral reaches to above the anal spines, and is as long as the head : ventral just I'eaches the vent. Second anal spine not qrute so long as the third, which equals the longest in the dorsal fin : its soft portion angular, one-fourth higher than the length of its entire base : caudal slightly emarginate. Scales — in oblique, straight (not sinuous) rows above the lateral line, and also as low as a level with the eye, below which all are horizontal : twelve rows between the occiput and base of the dorsal fin, and six across the cheeks. Colours — uniform scarlet, with a golden line along each row of scales and a nacreous spot across the free portion of the tail just beliind the base of the dorsal fin. A na,iT0w black edge to the dorsal, caudal, and anal fins. This species seems to be identical with Bleeker's : he observes that three of his specimens have twelve dorsal spines, but which appears to be due to the transformation of the first ray into a weak spine. There are two fine specimens in the British Museiun, one about IG inches in length, wherein the eye is 2 diameters fi-om the end of the snout : the other is 15 inches long, the diameter of the eye 1/4 of the length of the head, and H diameters from the end of the snout.

Four bright blue black-edged and slightly sinuous bands pass from the orbit across the opercles, the superior to about the ninth dorsal spme, the second to the fourth dorsal ray, the third to behind the last dorsal ray, and the fourth to rather below the centre of the base of the caudal. Fins yellowish, the dorsal with a dark edge and a light outer margin. Bleeker observes that three species have the upper surface of the head scaled, the vomerine teeth in a j\^-form, a deep preopercular emarginatiou and an edentulous tongue.

Fins — dorsal spines strong, increasing in length tc; the fourth, which equals that of the postorbital portion of the head, or 2f in the height of body, from it they decrease to the last, which is scarcely above two-thii-ds as high : the soft portion of the fin rounded, the height of the rays being equal to about "two-thii-ds of the highest spine. Pectoral as long as the head, reaching to above the anal spines. Second anal spine much the strongest, third slightly the longest, equalling the second of the dorsal fin, height of the longest rays a little more than that of its entire base : caudal emarginate. Scales — in oblique rows above t];e lateral-line and in horizontal ones below it. Gchurs — uniform yellowish-red with a dark spot in the axil : fins yellow : the upper third of the dorsal black with a white margin : caudal also with a black edge and white margin : a dark black mark across the middle of the first third of the anal.

FAMILY, I— PERCID^. 35 Length of head 2/7, of caudal 1/7, height of body 1/4 to 2/9 of the total length. iJ^es— diameter 3/10 to 2/7 of length of head, 1 diameter from the end of snout, and 3/4 of a diameter apart. Body elongated, its dorsal and abdominal profiles nearly horizontal. The maxilla reaches to below the first thii-d of the orbit : iuterorbital space flat. Vertical limb of preopercle with a moderately deep emargination to receive a very badly developed interopercular knob, its angle roimded, the whole limb finely serrated, and the lower Hmb almost entire. Two small sharp points on the operole. Teeth — ^villiform in the jaws, with a large canine on either side of the preniaxillary, between whicli are two smaller curved caniae-like teeth in the outer row, and several more similar ones along the upper jaw : in the lower jaw exists an outer row of curved, canine-like teeth, becoming larger posteriorly : in a triangular spot of vUliform ones on the vomer, the base being behind, and ii-om the centre of which a narrow band passes a short way backwards : those on the palatines in a naiTow line : an oblong patch on the tongue. Fins — spines weak, those of the dorsal increase in length to the third and fourth, which are half as long as the head, fi'om these they decrease to the last : soft portion of the fin, (as is also that of the anal,) rounded and not half so high as the spines, the longest ray equalling two-thirds the lenoth of the base of the fin. Pectoral extends rather beyond the ventral, but hardly to above the anal, it is two- thirds as Ion"- as the head : tliird anal spine rather the longest, equal to the diameter of the orbit but not so long as the rays, anterior anal rays one-third liigher than those of the dorsal, last anal ray as short as the spine, lower edo'e of fin strait^ht : caudal slightly emarginate. Scales — in parallel rows below and oblique ones above the lateral line. Colours — yellowish-gi'oy superiorly, becoming yellowish-white on the sides and abdomen, a broad black band passes from the eye to the middle of the caudal fin, dividing the dark back from the light sides, and a second band is continued from below the jaws to above the posterior end of the base of the anal, where it Ijecomes indistinct. A white pearly spot exists on the back under the middle of the spinous dorsal, and a second under the commencement of the rayed portion of the fin. Professor Peters showed me one of this species, nearly 4 inches in length, received from Paris as Serranus hignUatus, and I subsequently saw several more of the types in the Paris Museum. Habitat. — Seas of India to the Malay Archipelago. The type specimen of Cuv. and Val. came from Ceylon, the one figured (7| inches in length) I procured at the Andaman islands. 8.

The depth of the cheek from the eye to the maxillary bone equals two-tliirds of that of the maxillary bone. The maxilla reaches to below the middle of the orbit. Vertical limb of the preopercle with a slightly produced angle and almost horizontal lower limb, its vertical limb finely serrated, more coarsely so at its angle, the serrations being continued along the posterior half of its lower limb : opercle with two points, the lower being the most distinct. No interopercular knob. Teeth — canines in the premaxillaries and an outer row of curved canine-like teeth in both jaws : villiform ones in a triangular patch, having a posterior median elongation in the vomer, and in a narrow band on the palatines ; an oblong patch widest anteriorly of very fine teeth on the tongue. Fins — dorsal spines moderately strong, the third to the fifth being the longest and nearly equal to half the length of the head, from thence they decrease to the last which is about two-thirds of their height and equal to that of the rays. Pectoral pointed, nearly as long as the head, and reaching to above the anal spines : second anal spine the strongest and nearly equal to the length of the third or to the postorbital portion of the head, anal rays one-fourth higher than those of the dorsal fin. Scales — in obUque sinuous rows above the lateral-line to opposite the end of the soft dorsal fin where they become horizontal, as are also those below the lateral-line : on the summit of the head the scales extend forwards to above the anterior tlurd of the eye. Colours — pui-plish-red along the back, becoming more yellow below the lateral-line. In the upper third of the body there are oblique and in places sinuous golden lines along each row of scales, whilst below the lateral-line there are bands of dark pink, one passes along the first-third of the lateral-line and for the depth of lialf a scale below it : next is a golden band, one scale deep, ending on the lateral-line beneath the middle of the soft dorsal : below this is a rather wider reddish band passing from the eye to the lateral-line below the end of the soft dorsal : next follows a yellow band one scale deep going to the middle of the tail. Below this the fish is longitudinally banded with pink and j'ellow alternately. Fins yellow, vrith a light band, along the centre of the dorsal. Jerdon observed, (M. J. L. and Sc. 1851, p. 129) " I am jnclLucd to think that Russell's figure (125 F 2 30 ACANTHOPTERYGII. nouleni) is intended for this fish and not for a species of Mesopnon (? Sernmns) to which Cuvier refers it ■without however having seen a specimen. His account of the colour corresponds exactly with that of the nouleni of Madras. It is a very beautiful fish but one of very soft and flabby texture." The figure of nouleni is amongst Sir W. Elliot's drawings (No. 15), and to it Jerdon has attached the name of Serranus nouleni. Irrespective of this he sent a specimen to the British Mu.semn where it still exists, and is placed in the catalogue (i, p. 200) as Mesoprion dudecacanthoides, a. Half-gi-own ; not good state. Madras. Presented by J. C. Jerdon, Esq. In the unrivalled Paris collection, Cuv. and Val.'s two specimens of Serranns nouleni, C. V. still exist and are, as suggested by Jerdon, identical with the species dcsciibed alsove. Bleeker first pointed out that the lineolata Riippell and Russell's karooi are identical. I have figured both varieties owing to the great difl^erence I observed in their colouration, the size of the eye, &c. Fig. 1 is from the coast of Sind (7i inches in length) and its tints resemble those shown by Ruppell : fig. 2 is from Madras (7 inches long) and its colours are as described by Russell. In the ' Fishes of Zanzibar,' three varieties are recorded, (1) j-ellow witli pale blue streaks above the lateral-line, and about seven below it : (2) olive-brown with the lines darker blue : (3) \-iolet above, muzzle rosy, the oblique and longitudinal lines yellow. The form, however, with blue streaks has a well-developed interopercular knob, and can hardly be considered as a mere variety of this species. Habitat. — Red Sea, East coast of Africa, seas of India to the Malay Archipelago. It is very common ofl' Madras. 9. Lutianus lemniscatus.

Eyes — diameter 1/4 of length of head, I3 diameters from end of snout, and 3/4 of a diameter apart. Dorsal profile more convex than that of the abdomen, and slightly concave between the snout and the eye. The maxilla reaches to below the front edge of the eye. Vertical limb of preopercle serrated and with a shallow emargination : interopercle with a badly developed knob. Teeth — canines large in the upper jaw. Fins — dorsal spines rather strong, increasing in length to the fourth which equals the postorbital length of the head, and a little higher than the rays : pectoral not quite so long as the head : the second and third anal spines of about the same length and equal to the tliird of the dorsal fin : caudal emarginate. Scales — in oblique rows above the lateral-line, and horizontal ones below it. Colours —appear to have been dark red or yellow, with a wide brown or black band going from the eye to the centre of the caudal fin, and another less defined and narrow one below it but parallel to it. The above description is from Valenciennes specimen in the Paris Museum, which is in a good state of preservation. It was obtained from Ceylon. Habitat. — Ceylon to the Malay Archipelago. 10.

Eyes—diameter 4/15 of length of head, IJ diameters fi-om end of snout, and 1 apart. Abdominal jjrofile nearly horizontal, that of the dorsal more convex, l>ut from the orbit to the nape it is straight, or slightly concave : snout pointed : jaws of nearly equal length anteriorly : preorbital under the front third of tlie eye equals three-foui'ths of the diameter of the orbit in height. The maxilla reaches to below the anterior third of the orbit. Vertical limb of preopercle having a very shallow emargination, its angle rounded but not produced, both limbs finely serrated. No interopercular knob. Opercular points indistinct. Teeth— a pair of large curved canines in the premaxillaries, an outer row of curved canine-like teeth in the upper jaw more closely set but smaller than one which is present in the lower jaw : villiform teeth on vomer in a T-form (or a lanceolate patch, Bleeker) : in a band on the palate : and in an oblong patch, rather largest anteriorly, on the tongue. Fiws— dorsal spines weak, increasing in length to the third which eqtials that of the postorbital portion of the head, from thence they decrease to the last, which is two-thirds in the same distance : soft portion of the fin rounded, the highest ray equals two-fifths of the length of its base and is much lower than the spinous portion. Pectoral pointed, as long as the head, posterior to the hind nostril and reaching to nearly above the anal spines : ventral reaches two-thirds of the distance at the anal : second anal spine strongest but scarcely so long as the third which equals Ijdiameters of the orbit in length, its first rays highest and are as long as the base of the entire fin, its lower edge rounded, caudal emarginate. Scales — in oijlique rows above the lateral-line, and in horizontal ones below it : nine toten rows across the cheek. Colours — olive-gi-een with a dark band passing from the upper edge of the eye to the end of the spinous dorsal : a second through the upper fourth of the eye to the last few dorsal rays, and a third from the centre of the eye to the upper half of the base of the caudal fin and having a golden band below it, inferior to wluch is another dark FAMILY, I— PERCID^. 37 horizontal band, and tlie abdomen beneatb it golden : a deep black spot in the axil of the pectoral. Fins golden, a light edge along the upper margin of the spinous dorsal and fii-st five or six rajs : caudal with a darkish edge. Bleeker gives the colour of the body as greenish, with eight or more yellow sinning bands somewhat oblique above the lateral-line and horizontal below it, also some yellow spots on the head. The specimen I have figured is very different in coloui-ation from Dr. Bleeker's tj-]3e, but the proportions of the fish are the same, as well as the direction of the bands, which however are darker in colour, and widt-r. The description I have given is that of my specimen. In the British Museum there is a very interesting specimen, 4 inches long, taken at Amboina, and received from !Mr. Franks, as Mesojmon chrijsotmnia, young. It is of the same colour as the one I have figured, except that it has a black blotch on the lateral-line fi-om the '22nd to the 32nd scale. The proportions are much the same, allo-n-ing for size, but lingual teeth are not well discernible, and its scales are as follows, L. r. f-i, L. tr. 9/20. Hahitat. — Nicobars, from whence the late Dr. Stoliczka brought the specimen figui-ed (7 J inches long), to the Malay Archipelago. 11. Lutianus rivulatus, Plate XI, fig. 4.

Length of head 3/10 to 2/7, of caudal 1/.5, height of body 1/3 of the total length. iJ^es— diameter 2/9 of length of head, \\ diameter from the end of snout, and rather above 1 apart. The maxilla reaches to below the anterior edge of the orbit. Vertical limb of preopercle finely serrated even in the well-developed notch that is above its angle to receive the interopercnlar knob : horizontal limb of preopercle more coarsely serrated in its posterior portion than it is on its vertical border. Sub- and inter-opercles entire, the latter have a large triangular tuberosity directed a little upwards and backwards and received into the preopercular notch. Opercle with two flattened points, the lower the larger. In the very young the preopercular notch is badly formed, but as the interopercnlar knob increases in size, it by pressure causes absorption above it and thus forms a notch in the preopercular border. Teeth — one or two curved canines on either side of the premaxillaries, and an externa! row of curved canine-like teeth in either jaw, villiform ones in a triangular spot on the vomer, a narrow band on the palate, but none on the tongue. Fins — dorsal spines strong increasing in length to the third, fourth, and fifth, which are equal to about one-third of the height of the body, but not quite so long as the highest of the dorsal rays, they decrease in length to the last which equals two-thirds the height of the longest one : soft portion of the fin angularly rounded, the ninth to the eleventh rays being the longest. Pectoral as long as the head : ventral reaches the anus. Anal spines strong, especially the second which is slightly longer than the third and equals the highest of the dorsal fin : soft portion of the fin angular and one-tliird more than that of the dorsal : caudal slightly emarginate. Scales — in oblique rows above the lateral-line, and in horizontal ones below it, a strongly serrated shoulder scale, and two rows of broad scales over the nape. Coluurs — (in the immature) back olive, with a slate coloured spot in the centre of each scale, thus forming lines passing upwards and backwards ; abdomen greyish with horizontal golden lines crossing the centre of each scale, and vertical dark ones along their bases. Several bright blue lines pass downwards and backwards over the preopercle and opercle, andtwolarger ones along the snout. A large white blotch on the lateral-line opposite the tliird to the fiftli soft ray, having a wide black edge anteriorly and posteriorly in its upper third. This white mark covers tuui- scales transversely, is one below and three above the lateral-line. Doi-sal, slate coloured, superiorly I'eddish with a narrow white edge : pectoral reddish : ventrals slaty with a dark edge : caudal bluish, tipped with red. Generally vertical bands are more or less distinct. (In the adidt) as about 15 inches in lengtli, the mark on the lateral-line becomes indistinct, the golden shade is wanting, but the blue spots remain. The white edge to the fins is also usually absent. Hahitat. — Red Sea, East coast of Afi-ica, seas of India to the Malay Archipelago, and beyond. 12. Lutianus argentimaculatus, Plate XI, fig. 5.

Eyes— diameter 1/3 to 1/5 of the length of head, 1 to IJ- diameter from end of snout, and 2/3 to 1 diameter apart. The distance from the eye to the upper edge of the maxilla, equals from a little more to a little le^s than one diameter of the orbit in height. The maxilla reaches to below the first third or middle of the eye. Vertical limb of preopercle vriih a very shallow emargination, a rounded angle, and an oblique lower limb, the vertical border very iinely serrated, most coarsely so at its angle and especially along its lower limb. A slight swelling on the interopercle. Opcrcle with two blunt points. Teeth — large canines in the premaxillaries ; an outer I'ow of canine-like ones in either jaw, those in the mandible being much the largest. Villiform teeth in a lanceolate or A^-form, which sometimes has a central posterior projection, also La a band on the palate, and in the adult, a large scabrous patch along the centre of the tongue with small ones anterior to it : in the very 3'oung the tongue may be found destitute of teeth. Fins — dorsal spines not very strong, increasing in length to the thii-d, fourth, and fifth, which are from one-third to two-fifths of the height of the body, from thence they decrease to the last which is two-thirds their height : soft portion of the fin rather angular, its longest ray equalling three-fourths of the length of its ba-se. Pectoral nearly as long as the head, and reaching to above the anal spines : ventral nearly reaches the vent. Second anal spine the strongest and about equal in length to the third or nearly to the sixth of the dorsal : its soft portion angular, one fom-th longer than its entire base : caudal emarginate, in some specimens rather deeply lunated. Scrdcs — in horizontal rows above the lateral-line, in some specimens (especially young) they are a little sinuous but do not become regularly oblique until under the soft portion of the fin : bolow the lateral-line they are horizontal. Colours — cherry-red, darkest at the bases of the scales. The front edge of the anal fin pinkish-white as is also the first ventral ray. Upper margin of spinous dorsal orange. In some specimens there are dark spots on the dorsal, caudal, and anal fins. The very young have firom six to nine narrow, vertical, silvery-white bands, which become more or less lost as age increases. This species more especially differs from L. rosens by the latter having a rounded caudal fin, and from L. sillaoo in the latter having a higher spinous dorsal, and the rows of scales above the lateral-line being oblique in their direction. It appears questionable however whether the last is not merely a variety. Hahitat. — From the Red Sea and East coast of Africa, through the seas of India to the Malay Archipelago and beyond. It attains upwards of two feet in length and is good eating. 13. Lutianus roseus, Plate XI, fig. 6. Mesoprion rangns, Cantor, Catal. p. 14 (not C. V.) B. vii, D. \i, P. 16, V. 1/5, A.

Ei/es— diameter 2/9 to 1/4 of length of head, 1^ diameter from end of snout, and 1 apart. Height of preorbital equals three-fourths of the length of the eye. The maxilla reaches to below the first third of the orbit. Vertical limb of preopercle emarginate, and having an oblique lower limb, the whole being finely serrated, but most ccrarsely at its angle and along the lower limb. No tuberosity on the interopercle : sub- and intcr-opercles entire : opercle with two obtuse points. Teeth — one or two rather large and curved canines on either side of the premaxillaries : an outer row of slightly curved canine-like teeth in both jaws, largest in the lower : a triangular patch of vUHform ones on the vomer, without any posterior prolongation, a very narrow band on the palate, and an elongated band of minute ones on the tongue. Fiits — dorsal spines moderatcl}' strong, the fourth the highest, and equal to the length of the postorbital portion of the head ; from it they decrease to the last, which is three- fourths as high as the second, the soft portion of the fin ratlaer rounded, as high as four-fifths of the length of its base and equal to the fourth spine. Pectoral as long as the head behind the posterior nostril : ventral reaching nearly two-thirds of the distance to the anal : second anal spine stronger and rather longer than the third and equal to the length of the sixth of the dorsal fin, soft portion of the fin one-fifth higher than that of the dorsal : caudal rounded. Scales — in horizontal rows below the lateral-line, and also above it so far as to below the middle of the dorsal spines, where they commence going obliquely to the base of the soft dorsal, but becoming horizontal beyond the base of that fin: 15 rows between the occiput and base of the first dorsal spine. Colours — dark reddish-brown, becoming dull cherry-red below the lateral-line : fins with dark edges. This fish is so like the L. argentimaculatus, that had I not seen many specimens, I should have hesitated FAJMILT, I— PERCID^. 39 separating them further than varieties. It differs in its rounded instead of emarginate tail : in its yomerine teeth : its second anal spine and slightly in its scaling, &c. Cantor's specimen appears to be identical -vrith it. _ He observes : " according to Russell this fish is not much esteemed. At Pinang and Singapore, whei-e single individuals occur at all seasons, it is of excellent flavour and considered a great acquisition for the table. At ilalacca it is plentiful, and in our settlements and in the Straits it is known under the denomination of ' red rock cod.' " He gives D. xi-xri f^'^d as growing to 20 inches in length. Habitat. — Seas of India'to the Malay Archipelago. The specimen figured (8 inches long) is from Madras. 14. Lutianus sillaoo, Plate XII, fig. 2. ? Simrus silaoo.

Caudal slightly emarginate. Scales — the rows above the lateral-line first go rather obliquely towards the dorsal fin, more so under its soft portion : below the lateral-line they are horizontal. There are twelve rows anterior to the dorsal fin, and seven across the cheeks. Colours — back gTeyish-brow^l, chest orange, abdomen and sides of a light violet, each scale having a white edge. Spinous portion of dorsal greyish, but the soft with a more yellow tinge : pectoral reddish : caudal red with a black edge. Russell gives 11 dorsal spines, otherwise the fish resembles either this species or the L. jalmgarah. My reason for considering that I wrongly identified them in the " Fishes of Malabar" is that I find that it is this species which has lingual teeth, and the L. jahmjarali in which they are deficient, as observed by Russell. This fish is evidently very closely allied if not a mere variety of, L. raiu/us, but its dorsal spines appear higher, the rows of scales on its back more oblique, its colours difier, and before referring it to that species, further investigations are required. A figure is given for the purpose of drawing attention to it. Habitat. — Seas of India, attaining at least four feet in length. 15. Lutianus lioglossus, Plate XII, fig. 1.

The distance from the eye to the maxilla equals one diameter of the orbit. The maxilla reaches to below the middle of the eye. Vertical limb of preopercle with a very shallow emargination, and serrated in its whole extent : a very obscure interopercular knob. Teeth — strong curved canines in the premaxillaries, an outer row of curved canine-like teeth in both jaws, largest in the lower : viUiform teeth in a ^.-form in the vomer and a band on the palatines : no lingual teeth. Fins — dorsal spines of moderate strength, increasing in length to the fourth, which equals from two-fifths to one-third in the height of the body, the last spine is one-third shorter : soft portion of the fin somewhat rounded and its height rather less than half its length. Pectoral about as long as the head : ventral reaching rather above half the distance to the anal. Anal spines rather short, the third slightly the longest, and equal to three-fourths of the diameter of the orbit in length, soft portion of the fin highest in front, equalling about the length of its base, lower edge straight : caudal emarginate.

Ei/es — diameter 1/5 of fength of head, If diameter from end of snout, and 1 apart. Dorsal profile more convex than that of the abdomen. The distance between the eye and the upper edge of the maxilla equals one diameter of the orbit. The maxilla reaches to below the middle of the orbit. Vertical limb of preopercle with a shallow emargination above its rounded angle, which appears continuous with its oblique lower limb ; the whole of its vertical limb is finely serrated, but about the angle they increase in size, and along the lower limb are more widely apart. A distinct though small interopercular knob. Opercular points blunt. Teeth — a pair of large slightly curved canines in tlie premaxillaries, an outer row of curved, conical, canine-like teeth in both jaws, those in the lower being the largest : villiform ones in a j\-shape in the vomer, in a band on the palate but none on the tongue. Fins — dorsal spines moderately strong, the third the longest and nearly equal to one-third the height of the bodj', fi'om it they decrease to the last, which is only half its height ; soft portion of the fin rather rounded, not so high as the spinous, and its highest ray equal to two-thirds the length of its base. Pectoral as long as the head behind the front nostrd, and not reaching to above the anal spines, the ventral reaches a little above half way to the anal fin. Second anal spine stronger but shorter than the third, which equals the length of the seventh dorsal spine or one diameter of the orbit, soft portion of the fin angularly rounded, central rays the highest and equal the length of its entire base : caudal emarginate, being lobed in its last fourth, the upper being slightly the longer. Scales — in almost parallel rows to the dorsal profile both above and below the lateral-line, but becoming a little irregular below the soft dorsal, where they ascend obliquely upwards and backwards, but become horizontal again beyond the end of the fin: seven rows across the cheeks: 11 rows between the occiput and base of dorsal fin. Colours — back brownish-red, the base of each scale being darkest, whilst below the lateral-line it becomes of a lake-colour, having a tinge of orange along the lower surface of the body. A blue zig-zag line crosses the preorbital. Spinous portion of dorsal and anal grej-ish, the soft scarlet tinged with orange : pectorals scarlet : front edge of anal whitish. This species is evidently closely allied to L. rangus, it difi'ers greatly in colours, in wanting lingual teeth, in the number of its scales, the length of its spines, and the size of its eye. L. lioglossiis, Bleeker, has no lingual teeth, but its scales are oblique above the lateral-line, and much more numerous, being L. r. fyj. This species difi'ers fi-om L. sillaoo in having a small interopercular knob, its lower spinous dorsal, the direction of its scales above the lateral-line, &c. Habitat. — Seas of India, attaining two feet or more in length. It is esteemed good eating. 17. Lutianus quinqiielineatus, Plate XII, fig. 3.

Eyes— diameter 2/9 of length of head, 1^ diameter from end of snout, and 3/4 of a diameter apart. Body rather strongly compressed, dorsal profile having a considerable rise from the snout and being somewhat concave above the orbit. The maxilla reaches to below the middle of the orbit. Height of preorbital below the first third of the eye equals three-fourths of the diameter of the orbit. Preopercle with a shallow emargination above its angle, the whole of its vertical limb finely serrated, most coarsely so at its angle, lower limb entire : no interopercular knob : opercle with two verj- blunt points. Teeth — an exceedingly strong curved canine on either side of the prcmaxillary, and two intermediate small ones, an outer row of curved canine-like teeth in both jaws, largest in the lower : villiform ones in a ^-shape on the vomer, in a narrow band on the palatines and in an oblong patch along the centre of the tongue. Fins — dorsal spines moderately strong, increasing in height to the fourth, which equals the length of the postorbital portion of the head ; they subsequently gradually decrease to the last, which is two-thirds the height of the longest ; soft portion of the fin rounded, as high as the spinous, and its longest ray equal to two-thu-ds of the length of its base. Pectoral equals the length of the head behind the posterior nostril : the ventral does not quite reach the anal spines. Second anal spine stronger but not so long as the third, which equals the length of the last dorsal spine, soft portion of the fin one-third higher in front than the last ray, its lower edge rounded : caudal lunated. Scales — in oblique rows above the latei-al-line and horizontal ones below it : they extend forwards on the back to above the hind edge of the eye : seven rows on the cheeks. Colours — a blue band goes from the eye to the base of the last dorsal spine : two from the posterior-superior FAMILY, I— PERCID^. 41 angle of the eye coalesce under tlie sixth dorsal spine and proceed to the middle of the base of the soft dorsal : the fourth, also arising from the eye, goes along the lateral-line and opposite the sixth dorsal spine curves upwards, going to the end of the base of the soft dorsal : the fifth band, which is the broadest, commences just aljove the midtlle of the hind edge of the eye and goes to the upper half of the base of the caudal fin : the sixth from the lower edge of the eye to the middle of the base of the caudal. A dark mark exists at the base of the pectoral, a black blotch on the lateral-Une below the commencement of the soft dorsal fin. In the ' Fishes of Zanzibar' it is observed : " Diacope cceruleo-Uiieata. Riipp. N. W. Fische, p. 93, t. 24, f. 3 [not M. quinqzielineatus* Cuv. and Val.]." Sleeker, Lutjani, p. 40, observes: M. quinquelineatus, C. V. is described from the Mungi mcqndi, Russell, and has blue lines which superiorly are parallel to the profile of the liack and are continued to the base of the caudal. He doubts if Riippell's fish with the Lines going obliquely to the back is the same species. The specimen of Bloch's, Lutianus quinquelineatus, 9 inches long, No. 229, is undoubtedly this_ species, and differs widely from the figured quinquelinearis, the type of which is likewise in existence, both being in a good state of preservation at Berlin. Habitat. — Red Sea, East coast of Africa, seas of India : the specimen figui'ed is G inches in length and from the Andaman Islands. 18. Lutianus lunulatus, Plate XII, fig. 4.

Length of head 2/7, of caudal 1/6, height of body 1/3 to 2/7 of the total lengt-h. %es— diameter 1/4 of length of head, 1^ diameters from end of snout, and nearly one apart. The distance from the eye to the upper edge of the maxilla equals three-fourths of the diameter of the orbit. The maxilla reaches to below the first thu-d of the orbit. Vertical limb of preopercle with a shallow emargination and an oblique lower limb, its vertical limb is finely, its angle more coarsely serrated, lower limb entire. No interopercular knob. Teeth-- large curved canines in the intermaxillaries, an outer row of curved canine-like teeth in both jaws, largest in the lower : villiform ones in a _^-shaped band on the vomer, a narrow one on the palatines, and a small patch near the anterior end of the tongue. Fins—doTsal spines weak, the fourth the longest and nearly equaUing the length of the postorbital portion of the head, from it they decrease to the last which is about two-thii-ds its height : soft portion of the fin rounded, its highest ray equalling one-half the length of its base but not so high as the fourth spine. Pectoral much longer than the ventral, being nearly as long as the head : ventral reaching two-thirds of the distance to the anal. Second anal spine longer and stronger than the third : the anterior rays the highest, equalling the length of the base of the entire fin, its lower edge straight, caudal emarginate. Scales— in oblique rows above the lateral-Une and in horizontal ones below it : superiorly they extend forwards to nearly above the hind edge of the orbit. Co/oztrs— reddish-crimson superiorly becoming silvery-white on the abdomen : golden lines along each row of scales : dorsal, caudal, and anal with a black outer edge and an external white margin : a lunated black band at the base of the caudal fin extending along its outer edges to the end of the fin : pectoral and ventrals yellow. Bleeker places Diacope bitmniata, C. V. as a synonym of this species, but the tyjDO specimen in the Pans Museum has a distinct and rather well-developed interopercular knob, although the emai'giuation of the preopercle is not very deep. The specimen however is not an adult. Habitat.— Coast of Sind (where the specimen figured, 10 iuches long, was captured) to the Malay Archipelago. 19. Lutianus fulviflamma, Plate XII, fig. 5 and 6.

Eyes — diameter 2/7 to 1/4 of length of head, 3/4 to 1|- diameters from end of .snout, and 3/4 of a diameter apart. Snout rather pointed, the maxilla reaches to below the first tliii-d of the orbit : height from the eye to the upper edge of the maxilla equal to two-thirds of the diameter of the orbit. Vertical limb of preopercle with a shallow emargi- nation, its angle rather produced, and its lower limb oblique, the whole being finely serrated, most coarsely so at its angle, whilst the serrations are continued half way along the vertical limb. No interopercular knob : two opercular points. Teeth — strong curved canines in the premaxillaries, an outer row of curved, conical, canine- like teeth in both jaws, largest in the lower : villiform teeth in a ^-shape or T-shape on the vomer, in a band on the palatines, and an oblong patch on the tongue (in the adult) which is widest anteriorly. Fins — dorsal spines not very strong, the third of nearly the same height as the fourth and fifth, from whence they gi-adually decrease, the third is one-third higher than the rays and from two-fifths to half as long as the head : rayed portion rounded, two-thirds as high as its base is long. Pectoral as long as the head behind the front nostril : ventral not reaching the vent. Third anal spine about equal in strength but slightly shorter than the second, which equals one diameter and a quarter of the eye in length, and is of equal length with the first ray, which is twice as long as the last, lower edge of the fin concave : caudal slightly emarginate. Scales — in oblique rows above the lateral-line and horizontal ones below it : from six to eight rows on the cheeks : superiorly they extend forwards to above the hind edge of the eye. Colours — yellow or rosy along the back, with three or four, in the variety L. Etissellii* narrow and brilliant golden bands passing obliquely upwards and backwards from the lateral-line, and three or four similar golden bands below it, the first of which goes from the posterior edge of the orbit to the finger mark : the second from the middle of the opercle to opposite the end of the soft dorsal, where it becomes lost on the lateral-line : the third from below the orbit to the base of the caudal fin : and the fourth from below the base of the pectoral to the base of the anal. A large black blotch exists on the lateral-line opposite the commencement of the soft dorsal fin from the 22nd to the 28th or 31st scales, most of it being below the line and only reaching to one or two scales above it : in the variety L. Russellii, however, this mark is mostly above the lateral-line. The type specimen of Mesoprion monostigma at Paris is 3^ inches in length. The eye is a little less than 1/3 of the length of the head, and 1 diameter from the end of the snout. The second anal spine is of nearly the same length as the third and equal to 2| in the length of the head.f The Lidianus fidviflamma is found in two very distinct varieties : in one there are the yellow lines such as I have described and also figiu-ed (in pi. xii, fig. 6), and in this form, L. Bussellii, the distance from the eye to the snout and the size of the lateral blotch is a little more than we pei'ceive it to be in the tj-pical L. fidvi- flamma, of which I have also given a figure (pi. xii, fig. 5.) The two specimens were 7\ and 10 inches refspectively in length, and, examined together, certainly appear to be distinct species : but in comparing a large number of specimens, every intermediate variety in form and colotu- (except the yellow fillets of the L. Bussellii) are to be seen. Habitat. — Red Sea, East coast of Africa, seas of India to the JIalay Archipelago, and beyond. 20. Lutianus Johnii, Plate XIII, fig. 1.

Length 'of head 4/13 to 2/7, of caudal 1/5 to 2/11, height of body 2/7 of the total length. Eyes— diameter 1/4 to 1/5 or even 1/6 in large specimens of the length of head, 1 J to 1| diameters from the end of snout, and from 3/4 to 1 apart. Dorsal profile more convex than that of the abdomen. Preorbital equals three- foui'ths of the diameter of the orbit in height. The maxilla reaches to below the first third or middle of the orbit. Vertical limb of preopercle finely serrated, becoming more coarsely so at its angle, which is somewhat produced and rounded, its lower limb with a few .serrations and crenulations. A very indistinct tuberosity on the interopercle is sometimes present : opercle with two flat points the lower being the longer. The fry up to about 1| inches in length have a spine at the angle of the preopercle, which becomes absorbed as age advances, the lower limb of the preopercle is also strongly serrated : in a specimen 2\ inches long the spine remains only in the form of a strong denticulation, whilst there are seven more strong serrations along the lower limb. Teeth — cui-ved canines of moderate strength in the premaxillaries, an outer curved row of canine-like teeth in both jaws : viUiform ones in a triangular patch or elongated ^-form on the vomer, in a band on the palatines, and in an elongated pat'ch on the tongue in the adult. Fins — dorsal spines strong, increasing in length to the fourth, which is two-fifths of the height of the body, from this spine they decrease to the last, which is about one-fourth shorter, the soft portion of the fin somewhat rounded, its longest rays equal to five-sixths of the length of its base and exceed that of the highest spine. Pectoral nearly as long as the head : ventral reaches the vent : second anal spine usually slightly the longest and strongest, it equals the height of the third spine of the dorsal, the rayed portion rounded and rather higher than that of the dorsal: caudal slightly emarginate. Scales-— il\e rows above the lateral-line are parallel with the profile of the back, whilst those below it are horizontal. Scales on the dorsal profile only extend forwards to a level with the hind edge of the orbit. Colours — yellowish, lightest on the abdomen, with a large black finger mark, of varying depths of colour, on the lateral-line between the 22nd and 31st scales ; age, season, and locality all exercise an influence on this blotch : a dark line is almost invariably present along each row of scales. Fins yellow dashed with red : anal with a light front edge. In the young the ocellus on the side is larger, in a specimen 2| inches long it commences on the 19th scale, and is surrounded by a light ring, thus constituting Serranus pavo7dnus, Val., whose single specimen was a little over an inch in length : the observation of its having a strong spine at the angle of the " opercle" is evidently a misprint for " preopercle." Hamilton Buchanan points out the aflanity of Coius catus with the Booiidiawah of Russell as well as with his Mmigi mupudee (No. 110), also th&t Anthlas Johnii, Bloch, is nearly allied. It is readily distinguished from all allied species of Lutianus, with lateral blotches, recox;ded from the seas of India, by its having no oblique rows of scales on the body, all those above the lateral-line being parallel to the back and those below it being horizontal. The type specimen of Mesoprion fiwoipimnis, C. V. (a skin) belongs to this species, the lateral blotch has been omitted from the short description. Eahltat.—Sea.s of India, Malay Archipelago and beyond, attaining a foot or more in length. The specimen figxired is 65 inches long and from Madras. 21.

Vertical limb of preopercle with a very deep emargination succeeded by a broad and deep angle, its height forming half of that of the vertical limb, above the notch the serrations are very fine, on the roimded, produced angle they are coarse, and a few are continued along its oblique lower limb. Interopercular knob well developed. Teei/t— large canines in the premaxUlaries, an outer row of curved canine-like teeth in both jaws, the most jDosterior of those in the upper jaw being directed slightly forwards : vUliform teeth in a ^-form in the vomer, and in a band on the palatines, none on the tongue. Fins — the third to the fifth dorsal spines the longest and equal to two-sevenths of the height of the bodj', posteriorly they gradually decrease, the last being three-fourths of their height : soft portion of the fin rounded in the young, more pointed in the adult, the length of the highest ray being three- fifths of that of its base. Pectoral reaches to nearly above the anal, and is as long as the liead behind the posterior nostril : ventral reaches the vent. Second anal spine strongest and slightly the longest, it equals the highest in the dorsal fin : soft portion of the fin angular, the middle rays rather longer than its entire base. Caudal slightly notched in the young, more emarginate in the adult, the upper portion being the longer. Scales — go in oblique rows, directly upwards and backwards, above the lateral-line, and in sinuously oblique ones, taking the same course, below the lateral-line : six rows on cheeks : superiorly tliey extend forwards to above the hind edge of the eye. Free portion of the tail rather higher than long. Colours — uniform crimson, dorsal and anal fins having a black edge with a white external margin, and a white tip to the caudal lobes : a dark band along the base of the dorsal and anal fins : pectorals and ventrals yellow, the latter witli a dark tip : caudal dark purple. In the young — body crimson, with a black band commencing at the end of the dorsal fin, and covering a part of the hind end of the free portion of the tail and the caudal fin, except that it has a white outer edge. Bleeker suggests whether Biacope axillaris, C.V. vi, p. .532, may nut be this species, but Cuv. and Yal. observe that perhaps it is merely a variety of the marginafa. Halitat — Red Sea, Andaman islands to the South Sea, the largest specimen obtained (IH inches) is figured as the adult, one of the smaller ones is given (fig. 3) life-size. This fish attains at least IG inches in length. 22. Lutianus boliar, Plate XIII, fig. 4. Scioina bohar, Forsk. p. 46, No. 47. SjHinis lepisurus, Lacep. iii, t. 1.5, f. 2. Lutjanus hohar, Bl.

Teeth — moderately strong canines in the premasUlaries, an outer row of curved canine-like teeth in both jaws, a narrow villiform ^-shaped series in the vomer, and a narrow palatine band : none on the tongue. Fins — dorsal spines strong, the fourth the longest and equal to two-fifths the height of the body, from it they gi'adually decrease in length to the last which equals the length of the orbit, the soft portion of the fin rounded, three-fourths as high as the fourth spine, and its height equal to half the length of its base. Pectoral nearly as long as the head and reaching to above the fir.st anal spine : ventral reaches the vent. Second anal spine the strongest and equal to or rather longer than the third, and as long as the highest in the dorsal fin : soft portion of the fin one-third higher than that of the dorsal : caudal emarginate. Scales — in oblique rows above the lateral-line to opposite the end of the dorsal fin where they become horizontal, as they like^wise are below the lateral-Hne ; they extend forwards on the back to above the hind edge of the eye. Colours — purplish-yellow above the lateral-line and golden below it.. Generally no lateral blotch. The colours of the back are continued on to the lower third of the dorsal fin and cease at a dark grey longitudinal band which has a lighter one above it, edged superiorly with black and margined with white : caudal dark purplish-red having a white edge : pectoral, ventral and anal flesh-coloured having a yellowish tint. On the Malabar coast of India specimens are frequently taken that have a black lateral-blotch : also on the Coromandel coast some few have the lateral-mark faintly developed, but it is more commonly absent. This does not depend upon size or season, but may upon sex or locality : in specimens jjreserved in spirit the mark is liable to disappear. The one figured is 7 inches long, and from iladras.

Teeth — large canines in the premaxillaries, an outer row of curved canine-like teeth in either jaw : villiform ones in a ^-form on the vomer, and in a band on the palate. The specimen having had the tongue removed the existence or not of lingual teeth cannot be ascertained. Russell also omits to mention whether it is rough or smooth, a subject which he generally notices. Fins — dorsal spines strong, the third being three-c[uarters the height of the fourth which is nearly half the height of the body, they decrease to the ninth which is only 4/11 of that of the fourth spine : soft portion of the dorsal rounded, its height being rather more than half the length of its base. Pectoral nearly as long as the head ; the ventral does not reach half the way to the anal fin.

Scales — in rows parallel to the back above the lateral-Hne, and horizontal below it : 7 rows on the cheeks, none on the preorbital : superiorly they extend to above the hind edge of the eye, ten rows between the occiput and the first dorsal spine. Colours — silvery-grey on the back becoming yellowish white on the abdomen : longitudinal yellowish bands along each row of scales, which in the dry specimen appear sometimes in the form of occasional black spots : cheeks dashed with purple. Fins yellowish, dorsal, anal, and caudal edged with orange.

Two dorsal fins, the first with seven serines, the anal imth three: a forwardly directed recumbent spine in front of the base of the dorsal fin. Scales cycloid, of moderate or small size, frequently deciduous. Lateral-line complete, interrupted, incomplete or absent. Geographical distribution. — From the Red Sea, and East coast of Africa, through the seas of India and Malay Archipelago to North Australia and even beyond. Some are exclusively found in fresh water. Uses. — Although this genus consists of little bony fishes, whicli rarely exceed six inches tn length, and are generally far less, still they have their economic uses. The poorer classes eat them, they are extensively consumed by the larger fishes, fonning much of their sustenance during the di-y months of the j'ear, whilst owing to their formation they are easily dried without the emplovment of salt. Buchanan observes of his genus Chanda, which is mostly composed of species of ylHi6as6'is, that they "are very small, and of little value, although in many places abundant and used in considerable quantities : but as food they are insipid, and filled with small bones, for which defect then- size does not compensate." Cantor remai-ks that the "species of Apogon and Chanda are of little value as articles of food. At Pinang, they, as well as numerous other small fishes, the daily residue of the market, are used as manure." Some difficulty exists in ascertaining the species of tlois, genus to which a specimen belongs, and for the following reasons. The comparative length of the second or third dorsal spine to that of the body often differs in accordance with the size of the specimen : and local variations on this point seem to exist. The number of the soft rays is not constant. Scales are distincth' apparent in the adult of species in which thej^ are hardly visible in the very young. The lateral-line is subject to vai-iation. Colours likewise are not constant, but the character least subject to change appears to be the serrations on the sub- and inter-opercles, tlie preorbital, and around the orbit, but those on the vertical border of the preopercle are inconstant in some species.

As regards the hogoda, he observes it has 16 soft rays in the dorsal and 17 in the anal fin, and "a long transparent body devoid of scales," " but that it diflers in nothing remarkable from the two former (nama and phula) except in the number of soft rays contained in the back and vent fins, and in that contained in the pectorals, each of which has twelve." Amongst Buchanan's MSS. di-awings in Calcutta, is one lyV inches long, termed Centropomus phulchanda, which his notes show to be the phula, and a second 2^ inches long of the hogoda. Having brought together upwards of thirty specimens from different localities of Intlia and Burma, I find that this species is subject to variation, but some points remain the same in all. Although the comparative length of the longest dorsal spine varies, it retains its proportion to the third of the anal, which ajjpears to be invariably the longest in that fin : the last dorsal and anal rays are divided to their bases, (counting each as 1) and the following numbers exist in my specimens, D. 7 Ixs-TH-TS-Tr^ ^- tt-Ts -to-tt, certainly the most common is D. 7/tV, ^- tg : "^'■^*' of course if we count the last dorsal and anal rays divided to their bases as two, which FAMILY, I— PERCID^. 51 attainincf three or four inclies in and Verli.

Vertical limb of preopercle sometimes entire, more commonly finely serrated, but in some specimens, especially on the Bombay side of India, and in Burma, rather coarsely so : the double margin of horizontal limb of the preopercle serrated : sub- and inter-opercles entire. Preorbital with about six denticuiations on its inferior edge, and a strong one on its anterior superior angle directed towards the eye and about five more along the upper edge of that bone. Another spine at the middle of the posterior edge of the orbit, with five more, but decreasing in size along its upper half.

In Bui-ma the second anal spine is comparatively shorter than in Indian specimens. Colours — olive, having adark mark composed of spots on the shoulder, being the remains of a band present in the young. The margins of the vertical fins are usually somewhat dark. In the young, termed by Buchanan lala, the fish is of a bright yellow or orange colour, with tour or fave dark vertical bands which are formed of fine black dots. The first dorsal is nearly black, the second and the anal as well as occasionally the ventral have deep black edges.

Length of head 1/4, of caudal 1/4, height of body 1/3 of the total length. Ei/es — diameter 1/3 of length of head, 1/2 to 2/3 of a diameter from end of snout, and also apart. Body compressed : lower jaw rather shorter than the upper. The maxilla reaches to below the first third of the orbit. Preorbital stronglv serrated along its lower edge and having a sharp spine directed towards the orbit at its anterior-superior angle followed by several more along its upper edge. The whole of the upper edge of the oi-bit serrated. Vertical limb of preopercle entire, the whole of the lower edge of the horizontal limb strongly serrated, and a few serrations near the angle of its upper edge: sub- and inter-opercles entire. Teeth — villiform in jaws, vomer, and palate. Fins — second spine of the first dorsal fin the highest and equal to the length of the head behind the hind edge of the orbit, and rather more than half the height of the body below it ; the seventh spine rather longer than the sixth. Ventral reaches three-quarters of the distance to the anal. Third anal spine slightly the longest : caudal forked, lower lobe slightly the longer. Lateral-line — complete, it becomes straight opposite the first-third of the second dorsal fin. Colours — yellowish-olive : a golden spot on the occiput: Ijlack along the top of the first dorsal fin : second dorsal and anal darkest externally : front of each anal ray blackish : caudal dark along its base and also with blackish tips to each lobe. Buchanan observes that it has "the body short and transparent, and devoid of scales and ■\\-ith a yellow mark on the nape." It is said to resemble the hogoda in colour, and the ramja in shape.

The younger specimens are rather more oval than the adults : lower jaw the longer : a slight concavity ovei- the orbits, owing to a rise from the nape to the base of the dorsal fin. The maxilla reaches to below the middle of the orbit. Vertical limb of preopercle finelj' serrated, its lower double edge more coarsely so especially at the angle : posterior half of lower edge of interopercle strongly serrated.

Teeth — villiform in the jaws, in a single ^-shaped row in the vomer, and also present on the palatines : tongue usually with a narrow band along its centre. Fins — dorsal spines strong, transversely lineated, giving a sen-ated appearance to the second, which is the longest, and equal to the length of the head behind the front margin of the orbit, or even slightly longer : the ventral does not extend to the anal : second anal spine the strongest and nearly as long as the tliird, "which almost equals the third of the dorsal : caudal deeply forked, upper lobe usually the longer.

Eyes — diameter 2/5 of length of head, 1/2 a diameter from end of snout, and 3/4 apart. Lower jaw the longer : cleft of mouth very oblique. The maxilla reaches to below the front edge of the orbit. Preorbital with seven sharp teeth along its inferior edge : a spine at the posterior-superior angle of the orbit. Vertical limb of preopercle entire except two serrations just above its angle : its horizontal double edge serrated, the lower the most coarsely so : sub- and inter-opercles entire. Teeth — villiform in jaws, vomer, and palate : a small central band at the root of the tongue. Fi/is — second spine (jf the dorsal longest and eqilal to one quarter or two-ninths of the total length, and rather above half the height of the body below it : ventral reaches two-thirds of the way to the anal fin : third anal spine usually slightly the longest but not equalling the longest of the dorsal. Scales — a single row along the suborbital ring of bones. Lateral-line — curves downwards under the middle of the soft dorsal, but in an interrupted or semi-interrupted manner. Colours — Silvery with a burnished lateral band : the interspinous membrane between the second and third dorsal spines black : a dark longitudinal band along either lobe of the caudal. Dr. Giinther observes, P.Z.S. 1871, p. 655, that Ambassis iniops, Giinther, differs from A. urotcenia, Bleeker, by the smaller size of the eye, and by the lateral-line being continuous. The diameter of the eye in A. urotmiiia is equal to the length of the postorbital portion of the head. In A. miops the lateral-line forms a distinct and continuous curve from opposite the end of the dorsal fins, whilst there are two rows of scales along the suborbitals. Habitat. — Seychelles, Andamans, and the Malay Archipelago. It closely resembles the A. gymnoeephahts, but its lateral-line is entire : it has only one row of scales along the suborbitals and the comparative height of its body diflers. It appears to be common at the Andamans.* * Bogota infuscata. Blyth, J.A.S. of Bengal, 1860, p. 139 ; Dav, Proc. Zool. Soc. 1869, p. 515. D. lU/Jj, V. 1/5, A. 3/8, C. 17.

Geographical distribution. — From the Red Sea and East coast of Africa, througli tlie seas of India and Malay Archipelago to Australia, and even beyond. These small fishes are marine, and are numerous in sheltered spots" as inside harbours, and some have been captured at the mouth or even a short distance up tidal rivers and backwaters. In the Indian region they are most numerous off the Sind and Bombay coasts, and Andamtm islands. Jjses. — Although small, they are eaten fresh, dried, or salted, by the natives of India. The fishes of this Genus, after having been primarily divided in accordance with the number of spines in the first dorsal fin, have undergone various subdivisions, the most popular of which seems to be as regards their coloui'S. The lono-itudiually or ti'ansversely banded ones, those which possess or are deficient in the caudal blotch, have been separated on several plans, and although such may possess advantages they appear to be counterbalanced by marks sometimes disa]3pearing or perhaps never having existed in the specimen. Conse- quently coloui- will still be omitted from indicating the position of any species, and the number of spines, rays, and scales employed for this purpose. It seems also questionable whether any considerable value can be placed upon the serrations about the bones of the head, especially of the orbits, as such appear to be more distinct in some specimens than in others, and may vary with age.

Eyes- diameter 3I to 1/4 in length of head, 1 diameter from end of snout, and also apart. The maxUla reaches to below the first third of the orbit. Preorbital moderately serrated in the last two-thirds of its lower edge. Vertical limb of preopercle with fi-om 12 to 14 serrations, the two at its rounded angle being much the strongest, alono' the lower limb are about eight weaker ones. Sub- and inter-opercles with fine serrations at their approximating edges, which may or may not be blunted with age, those from the Malabar coast appear to be the most strongly serrated. Upper opercular spine small, the lower large and strong, and its length equal to about two-thirds of the diameter of the orbit. Shoulder-bone, also the one in the axilla, serrated, very strongly so in the young. Teeth— an outer somewhat enlarged row iu the jaws, fine ones likewise generally present on the vomer ancf palatines, more especially in the young. J'//(,s— dorsal spines moderately strong, the tliird and fourth the longest, of about the same height and equal to half that of the body below them : second anal spme usuaUy the strongest, and sUghtly shorter than the third : caudal forked. Colours— hac'k bluish-grey, becoming white on the abdomen, with a tinge of gold along the cheeks and snout. Three longitudinal reddish-brown bands, having a sHght convexity downwards, pass along the body : the upper from ia front of the dorsal spmes to the eio-hth or ninth : the second from the occiput to the end of the soft dorsal having reached the lateral-line in its concave course : the third from the back of the head to the lower opercular spine, and continued m a curved direction to the centre of the caudal fin. Sometimes a fourth band is present along the abdomen. Ventral and anal with a yellow tinge along their centres. Dorsal interspinous membrane milk-white, with a black mark in its upper two-thirds between the third and sixth spines : a second commences at the eighth spine, and is continued along the whole base of the soft dorsal : upper edge of first three dorsal rays tipped with black : caudal with two oblique bands across each lobe : eye yellowish-red.. ?0 ACANTHOPTERTGII. In the younrj there are two strong spines at the preopercular angle. Dr. Klunzinger, I.e. observes upon having ovAy found 10 spines in the first dorsal fin. Dr. Giinther, ' Fische d. Sudsee,' p. 2G, in answer to this, remarks that during a London fog he has found 11. I may complete the discussion by stating that in my collection I have specimens representing both numbers. Col. Tickell, MS. remarks that this fish is termed the Paddy or rice eater in Ai-racan, in consequence of the yomig lacing so frequently found in the inundated rice or paddy-fields. Habitat — From the Red Sea and East coast of Africa through the seas and estuaries of India to the Illalay Archipelago and north coast of Australia. It is a common fish, attaining 12 or 13 inches in length. Hamilton Buchanan left an excellent figure of this fish illustrative of his Coins trivittatus : it is labelled Holocentrus kafkaya, and was reproduced by General Hardwicke. The species is not uncommon at Calcutta in the tidal Hooghl)*, whilst the T. puta, to which Buchanan's description has been refen-ed, does not appear to ascend so high, although I have taken it, along with other marine fishes, in the Sunderbunds. 3.

Eyes — diameter 3|- to 3\ in length of head, 1 diameter from end of snout, and also apart. The maxilla reaches to below the first FAMILY, I— PERCID-cE. ' 71 third of the orbit. Preorbital very finely serrated on its lower edge in the adult but more distinctly in the young. Preopercle nearly evenly serrated, most coarsely at its angle: sub- and inter-opercles entire, in some of the young they are rough or even serrated at their approximating edges. Lower opercular spine the longer, about 2/3 as long as the orbit, but not equalling the length of T.jarhiia. Teeth— \il\iiorm in the jaws, with an outer somewhat enlarged row : deciduous ones present in the young on the vomer and said also to exist on the palate. Shoulder-bone serrated, and two or three strong spines on the bone at the axilla. Fins — dorsal spines modei-ately strong, the fourth slightly the longest and equal to half the height of the body below it, their length decreases to the last but one, which is only two-thirds or three-fourths as high as the last : second anal spine the strongest, but rather shorter than the third : caudal emarginate. Scales — above the lateral-line a Kttle smaller than those below it. Colours — silvery, with four horizontal blackish-brown lines, the first from the second to the last dorsal spine leaving a narrow yellow intervening space between them : the second from the nape to the last few dorsal rays, and ending by being continued on to the fin as well as joining the line below it : the third (which is often the last) from the snout to upper part of the tail : the lowest (often absent) from the base of the pectoral to the lower caudal lobe. Dorsal fin with a black blotch between its third and its seventh spines, and a dark band along the upper portion of the rays. An horizontal black band alono- the first half of the anal fin. Caudal with two obliijue bands across its lower lobe, and two also across its upper, the superior of which is interrupted in the adnlt, the lobe has likewise a black tip. In the yoHiiq the colours are much darker, and due to innumerable fine brown spots they appear as if they were dark witli two light bands only half the width of the darker ones. The anal fin has two large black spots, one on the interspinous membrane" and continued on to the first three rays : the second is confined to the last three rays. A large black shoulder spot is sometimes visible. There are teeth on the vomer. Variety. — In a small specimen from Madras, 2^ inches long, there are D. V"' ^^^ tw S^'st spines apparently being absent, it is otherwise identical with the young of this species. Therapon cinereus (Cuv. and Val.) Giinther in the British Museum is this species, in which the bands, though very faint, may still be traced : as the condition of the specimen is good, either it must have been somewhat of an albino variety, or else it has been kept in such a light that etiolation has resulted. Ealita.t.—'Ea.st coast of Africa, seas of India, through the Malay Archipelago to China, attaining at least six inches in length. Genus, 15 — Datxia, Cwv. and Val. Mesojmstis, sp. Bleeker.

The maxilla does not quite extend to beneath the anterior edge of the orbit. Snout pointed. Preorbital serrated along the last half of its lower edge. Preopercle serrated along its vertical margin. Teeth — villiform in jaws, none on the palate. Fins — fom-th and fifth dorsal spines the longest and rather more than half the height of the body : second anal spine very strong, longer than the third, and exceeding the length of the longest in the dorsal fin : caudal notched. CoZoMre^silvery, darkest along the back : a nan-ow black outer edge to the dorsal fin : a band along the middle of f^ie anal, which also has a dark margin. The young appear to have longitudinal bands. As Cuvier observes, this fish has a more elevated body than in the tj'pical Therapons, a somewhat concave profile, and pointed snout, the dorsal spines being stronger and their bases occupying a comparatively greater extent of the back than the rays, and there being a very slight notch between the last two. In fact it is his first species of Datnia, a genus which some Ichthyologists consider ought not to be retained. Hahitat. — Cape seas, geas of India to the Malay Archipelago and beyond. I never obtained it in India, saw it in a local collection there, or observed any figure of it amongst drawings of Indian fishes, but as it is found in the Malay Archipelago, stray ones may very possibly be occasionally captured on the coast of India. 72 ACANTHOPTERTGII.

Pectoral equals the length of the head : second anal spine the longest,* and in the adult a fourth longer than the fifth of the dorsal, it is striated in grooves along its front edge : caudal cut squiire or slightly emarginate. Colours— sOvery, darkest along the back, and in the young with an indistinct darkish band along the muldle of the body : a dark' spot, having "steel blue reflections, exists on the opercle : snout dark: a dark streak along the dorsal fin most distinct ui the immature. In a specimen 3| inches long the snout is dark, and there is a large black blotch covering 2/3 of the opercle. Bleeker considers that P. arfjyrenm is distinct from P. guoral-a, the former bemg distiagmshed by a more obtuse and more convex profile, by the eyes being considerably larger, and by the second anal spine being weaker and shorter. In examining a series of specimens of these fishes, it appears to me that one can hardly separate one species from the other, the difierence being probably due to age and perhaps sex. In the young the eye is 1/3 the length of the head and only 1/2 a diameter from the end of the snout, and the second anal spine generally only equals the length of the postorbital portion of the head. Habifat.Seas of India to the Malay Archipelago, said to have been captured in fresh water.

Snout pointed and somewhat compressed : jaws of equal length. The maxiUa reaches to below the posterior nostril. Preopercle emarginate, finely serrated, most coarsely so at its rounded angle. Teeth— in jaws villiform, the outer row being scarcely enlarged. Piits— dorsal spines strong, the fourth the highest, equal to the length of the postorbital portion of the head and higher than the rays. Pectoral as long as the head reaching to above the anal fin : the ventral does not reach to the anal : second anal spine the strongest and longest equal to the third of the dorsal : caudal emarginate. Ccecal appeiularies-xeTj long. Colours — silvery, with a black blotch at the posterior- superior corner of the opercle : upper half' of body with numerous black spots, which in some do, in others do not, form undulating bands : a black spot at the base of each dorsal spine and ray : dorsal and caudal dark edged : anal blackish in its front half. The yo2mij are silvery, with the opercular spot distinct, a black mark in the axilla, and a few dark spots over the base of the pectoral fin : dark spots on the dorsal almost form bands along its upper and lower thirds : a dark band is likewise present along the centre of the soft portion : last half of caudal dark grey. The form of this species is very similar to P. nageb, Riippell, which, however, has D. tt-^, L. 1. 42-43, and the eye 1/6 of length of head. The second anal spine comparatively longer. In the specimen in^ Berlin, 16 inches long, the spots are sprinkled over one side of the body, but in bands as shown in RiippeU's figure on the other. A specimen of P. suiUiim, C.V. at Berlin from the Cape of Good Hope makes it doubtful whether P. operculare may not prove to be a variety of that species.

Length of head 2/7, of caudal nearly 1/G, height of body 4/13 of the total length. i^)/es— diameter 2/7 of length of head, rather above 1 diameter from end of snout, and 3/4 of a diameter apart. Dorsal profile much more convex than that of the abdomen, a considerable rise from snout to the base of the dorsal fin, with a shallow concavity over the forehead. Lower jaw somewhat the longer, the maxilla reaches to below the hind third of the orbit. Vertical limb of preoporcle somewhat emargiuate and finely serrated in its whole extent, but the serrations ai'e concealed by the scales : preorbital, sub- and inter-opercles entire. Two very obtuse spines on opercle. Lips thick, they, the chin, and under surface of lower jaw with innumerable closely-set fine papilla?, having barbel -like prolongations, but without any gi-oove or deep pores. Teeth — villiform ones in jaws, vomer, and palate, the upper jaw with an outer row of from twenty to thirty conical ones, of no great size, and a similar row hut of lesser number in the lower jaw. Fins — dorsal spines of moderate strength, very low in proportion to the rays, they increase in height to the third which equals three-fourths of the diameter of the eye in length, those posterior to it gradually decrease in length to the last but one, the last being higher and its length equal to three-fourths of that of the third spine : interspinous membrane deeply notched : soft portion of the fin highest anteriorly where the rays equal the length of the postorbital portion of the head, whereas the last only equals the height of the third dorsal spine : the pectoral equals the length of the head excluding the snout : the ventral reaches a little more than half way to the base of the anal : third anal spine much longer and stronger than the second, its length equal to the highest in the dorsal fin, soft portion of the fin similar to that of the soft dorsal : caudal emargiuate. Scales — small, finely ctenoid, and covering all the fins. Colours — blackish-grey vrith the fins darker. Eahitat. — Sind and Meckran coast, being termed BaJi-ri, at Gwadur. Although the species was not uncommon the specimens were so large, 1 was unable to bring away more than the skin of the smallest one, 18 inches in length, which was preserved in spirit, and from which the figure was taken. Genus, 19 — DiAGRAMiiA, Guv. PlectorhyncJius, pt. Lacep. Branchiostegals six or seven : pseudohrmicliiie. Body ohlonc/, compressed, with the upper profile of the head parabolic. Eyes of moderate size. Mouth small, slightly pirotractile : lipjs thick and folded hack. Preopercle serrated : siih-orhitals entire. Four or six oj^ew piores on the under surface of the louver ja%o but no median groove. Teeth in jaws villiform, without canines : palate edentulous. One dorsal fin more or less receivable into a groove along its base, having from 7iine to fourteen spines: anal with three. Caudal not forked. Scales ctenoid, usually small, hut of a moderate size in some species, present on the head excluding the lower jaw, and visually continued on to the soft dorsal and anal fins. Air-vessel simple, destitute of any constriction. Pyloric appendages feiu. Oeograpjhical distribution. — From the Red Sea and East coast of Africa, through the seas of India to the Malay Archipelago and beyond. These fishes are much more abundant oif Sind and as far as Bombay, than they are down the Malabar or Coromandel coasts of India. In fact Russell does not figure one of the genus. Uses — generally not in much esteem as food, but some are good eating. The species forming this genus are subject to considerable variations in the number of the dorsal rays, whilst a spine* more or less may exist. Irrespective of the differences observable in the dorsal fin, the colour varies almost as widely as amongst the Serrani (see page 9, ante). The ground colour is usually white or yellow in those which are striped longitudinally : there are, as a rule, component parts of two very distinct bands, the upper commencing above the eye by a wide base including the second dorsal spine and ending in a wedge- shaped form along the soft dorsal, both the roots of tliis band and its terminal extremities may be composed of several narrow ones which coalesce : next there is a central broad one gomg from the eye to the middle of the caudal fin, also terminating in a wedge-shaped form, this broad band may be made up of two parallel naiTow ones, separated by an interspace : below this central band may be a lower or third one, either single or constituted of one or more narrow ones. If this is the correct solution of the composition of the ornamental colouring of these fishes, it seems by no means uidikely that some of those now recognised as species, will have to be considered as varieties. The form of the caudal fin often varies considerably in the same species, and this does not appear to be simply due to age. SYNOPSIS OP SPECIES. 1. Biagramma crassispinum, D.

Eyes- diameter fi-om 1/3 to 2/7 of length of head, 1 diameter from end of snout, and nearly 1 apart. Dorsal profile much more convex than that of the abdomen, profile of head paraboUc. The masiUa reaches to below the front third of the orbit. The depth of the preorbital nearly equals the diameter of the eye. Vertical limb of preopercle very slightly emarginate, its angle rounded, and the whole finely and evenly serrated. Teeth — fine. Pins —dorsal spines strong, every alternate one broadest on one side, they increase in height to the fourth, which equals two-fifths or one-third of that of the body, the last being about one-fifth shorter, soft portion of the fin gradually increasing in height, its middle third being higher than the spinous. Pectoral as long as the head without the snout : ventral reaching three-fourths of the distance to the anal, the second spine of which latter fin is stronger and slightly longer than the third, equalling the length of the head behind the middle of the orbit : caudal rounded, or cut rather square. Colours — D. lineatum, yellowish-white superiorly, becoming white alono- the sides and on the abdomen : about six chestnut-coloured bands, the upper being wider than the gi-ound colour, extend from the head along the body, the two first below the soft dorsal fin, coalescing and being continued along its centre as far as its termination in a wedge-shaped form : the third passes through the upper thu'd of the eye along the side to a little above the centre of the caudal fin, and in its course touches the lower edge of the soft dorsal : the fourth arises by one or two roots below the eye, and goes to the lower third of the caudal, and joining vrith the last band, is continued in a pointed manner to its termination : the fifth proceeds from the angle of the mouth to the lower edge of the base of the caudal, and the sixth from below it to the lower edge of the soft portion of the anal : fins yellow, with sometimes one or more dark blotches : dorsal with a dark edge, which may be confined to its soft portion : three oblique bands across either caudal lobe, which are occasionally broken up into blotches : a band along the middle of the anal fin. Variety. — Diagramma alhovittatitm, silvery-white above, becoming yellowish- white below, a dark chestnut median band commences on the occiput opposite the middle of the eye, and goes to the anterior dorsal spine, being contmued first along the bases of the spines, but attaining their middle posteriorly, it joins the second band: the second chestnut band commences on the snout and passes above the eye, and gradually increasing in width posteriorly, arrives at the base of the soft dorsal, and is continued along its middle as far as its termination in a wedge-shaped form : the third baud, which may be considered the coalescence of the two in D. lineatum, extends from the snout through the eye, becomes the widest, and arriving at th& centre of the base of the tail, diminishes in width, and is continued in a wedge-shape to the termination of the fin. Fins yellow, a narrow dark edge to the spinous dorsal, which increases in width over the soft portion : two oblique dark bands across the upper caudal lobe and one along the lower : a darkish edge to ventrals, and the outer half of anal with a dai'k band. In some specimens a wide chestnut coloured band appears to extend from below the eye, covering the abdomen, and leaving only a very nari-ow interspace of whitish ground colour between it and the band immediately above it; in such specimens the colour of the body appears to be chestnut, with three narrow white or light longitudinal bands. It must, however, be evident that other points being identical, this form is merely the D. lineatum* with three instead of six longitudinal body bands, which, due to their decrease in number, show an increase in width. Bleeker (Revis. Fleeter, p. 282) observes that alhmittatum has no dark border to the spinous dorsal, nor spots on the paired fins, whilst the dorsal spines are of about equal length. A frontal profile little or not at all convex, L. r. f|. The specimen I have figured has L. r. |-f, and appears to so connect the two species that it is difficult to say to which it belongs, the colours and form of the spinous dorsal being such as refers it more to lineatum than albovittatum, but the number of scales, absence of spots on the paired fins, and a black edge to the spinous dorsal, being such as have been pointed out as characteristic of alhovittatmn. In tiie Catalogue of Fishes of the British Museum, i, p. 330, Bodian Cuvier, Bennett Fish. Ceylon, p. 13, fig. 13 is referred to Diagramma lineatum.-^ In the "Fishes of Zanzibar," p. 28, under the head of Diagramma Cuvier i, is Seba, iii, 27, 19, Bodian Cuvier, Bennett, and Diagramma Seba, Bleeker, whilst D. Lessonii (I. c.) is recorded as a distinct species. In the " Fische d. Sudsee," p. 28, the synonyms for D. Lessonii are D. seba, Bleeker, but Bennett's fish is not referred to. Bleeker in his revision of these fishes (pp. 288-9) observes that Lessonii is very near lineatus, and may represent its adult age, the formula of the scales and rays being identical. Tm-ning to Bleeker's figure of D. Sebre, = D. Lessonii, Giinther, the anterior dorsal spines in the former appear to be more elevated. If the two longitudinal bands from the eye m the figure refen'ed to_ were amalgamated, and the fin marks reduced to blotches or spots so frequently the case in large specimens, * lOnnzinger (Verb. z. b. Ges. Wien. 1870, p. 736) observes that D. BlocUi differs from D. alhovittatum in having 10 dorsal spine3, &c., and places D. Kneatimi (1. c. p. 735) as a variety of D. pwnctatum. f It is also a subject worthy of consideration whether Plectorhyiichus polytmnia = P. polytcsnioides, Bleeker, L. r. yy, is not identical with P. Ooldmani, = P. Iwimatochir, L. 1. VV", the former having a bluish instead of a yellowish-white ground colour, and the bands being light brown instead of darlc chestnut, whilst the deficiency of colouring matter accounts for the absence of spots on the fins of the former but present in the latter. The colouring of P. GolJmani again approaches very nearly that of P. or IHagramma Seba, Bleeker, L. 1. W") which, as observed, is considered by Dr. Gunther as identical with D. Lessonii, which is a variety of D. Imeatum. 80 ACANTHOPTEETGII. thecolours would considerably resemble those of Uneatum; the tloree upper bands -svould only hare to be conjoined and continued on to the dorsal fin, when alhovittaium would be reproduced. But Bleeker observes that the scales are L. r. •-'y, and more than are found in Ihieatum or Lessonii : were it not for that fact, one would almost feel inclined to agree with Dr. Giinther, and place it as another sj-nonym of Uneatum. It is very desirable that some one residing where these fishes are to be obtained in quantities, as Sind or the Andamans, would bring together a large number, of all sizes, at different seasons of the year, carefully examine the sexes, and the number of their ciecal appendages whilst they are in a fresh state, making a comparison between aU the difierently coloured ones, the result I anticipate would be, as in the Serrani, that a conclusion must be arrived at, that there are many varieties but comparatively few species. EahHat.—B.ed Sea, seas of India to the Malay Archipelago and beyond. The specimen figured was given me by Dr. Shortt, Inspector General of Vaccination for the Madras Presidency, who received it whilst fresh at Cuddalore in 1867.

Teeth— generic. Pr/ts— dorsal spines of moderate' strength, every alternate one strongest on one side, the second nearly as high as the thii-d which is the longest in the fin and equals from half to two-fifths of the height of the body, the last being from one-third to one-half shorter : soft portion of the fin gi-adually increasing in height, its middle third beting higher than the spinous. Pectoral as long as the head without the snout : ventral reaching three-fourths of the distance to the anal, the second spine of which latter fin is stronger and longer than the third, equalling the length of the head posterior to the middle of the eye : caudal rounded or cut rather square. CoZojtM— yellowish superiorly, becoming white on the sides and beneath, the body -with several chestnut bands nearly or quite as vdAe as the ground-colour. There may be four or five complete or interrupted horizontal bands along the snout and head, which form thi-ee or four on the body : the highest gointr to the base of the spinous dorsal •. the second, usually interi-upted, to the first two-thu-ds of the base of the soft dorsal : the thii-d bifurcating beyond the end of the pectoral fin divides into two, the superior, often mten-upted, going to the upper portion of the caudal fin, and the inferior to its lower portion, on the caudal these two bands gradually approximate or even coalesce, and are so continued to the centre of the fins termination : the lowest body band goes from below the pectoral fin to the end of the base of the anal. Spinous dorsal with a narrow dark upper'edge : a dark angular band along its base, which is anteriorly two-thirds as high as the spines, but ending in a point at the base of the last spine : a similar wedge-shaped band exists on the soft dorsal, its base beinglilong the origin of the first ten or twelve rays and its apex at the upper termination of the same rays. Pectoral yellowish, with a dark blotch covering all but its margin : a black band along the middle of the anal and an oblique one across either lobe of the caudal, the lower being sometimes divided mto two, or havmg a light spot in its centre. -r^. , n r, t ^ i p i_ The Orientale figured in Bloch, Cuv. and Val., and in Garrett s Fische d. Sudsee shows much ot the colouring of D. pica .—a band passes vertically from the upper surface of the head behind the eye to the angle of the mouth, and from it proceeds a wide single horizontal one along the body which is more or less mterrupted but eventuaUy constitutes a central caudal band : from this lateral band one may proceed directly upwards and form the basal blotch on the spinous dorsal, or it may be interrupted in this course ; a second band proceeds upwards and forms the blotch on the soft dorsal : a lower band likewise proceeds from the base of the pectoral to the end of the anal joining the band on that fin : the marks on the fins are as in the first variety. That this species is very closely related to D. Uneatum is apparent: its colouring is evidently a modification of identical bands somewhat diflTerently disposed. The doreal spines however differ, and to judge by this question solely would cause Bennett's figure of Bodian Cuvier, p. 13, fig. 13, to be a Diagramma with much the form of Orientale and the colouring of D. Uneatum. Cantor indeed observes of it, "m the absence of a detailed description * * the species cannot be determined." Habitat.— Ued Sea, seas of India, to the Malay Archipelago, and beyond.

Pectoral as long as the head excluding the snout : the second and third anal spines of about the .same length and equal to about half the length of the head or the height of the sixth dorsal spine : caudal cut neai'ly square, or with rounded angles. Colours — This fish having been divided into several species due to variations in colour, 1 propose describing such in accordance with what appears to me to be that most readily explained. IJiaijrainma Blockii (variety) orange yellow or white, with chestnut brown or black longitudinal bands, the upper three of which commence between the eye and the base of the first dorsal spine, the sujierior narrow runs along the base of the spinous dorsal and joins the one on the doi'sal fin : the second and third are broader and coalesce above the middle of the pectoral fin, becoming lost below the base of the soft dorsal and on the upper edge of the free portion of the tail : the fourth and fifth proceed from the snout, through the eye, and go direct to the centre of the base of the caudal, where they join and are continued to the end of the tin ill a wedge-shaped form : below these bands are one or two more, the upper of which goes to the lower edge of the free portion of the tail. Dorsal fin with a narrow black margin, a broad dark band runs from the upper two-thii-ds of its second spine backwards and do-i\Tiwards to the base of the fin, leaving the lower third of the second and third spines uncovered, this band is sometimes interrupted (as shown by Bloch), causing a black spot to exist between its third and fourth spines ; if continuous (as in PI. sxi, fig. 3), it coalesces with the upper body band, and is continued in a wedge-shaped form to the posterior-superior angle of the soft dorsal tin. Caudal with a central wedge-shaped dark band, and a cross-band over its upper and lower angles, thiese are frequently broken up into spots : the lower half of the anal and the end of the ventral black.* A very interesting form of colouring exists in a specimen with D. -5% from Madras, presented by Dr. Jerdon to the British Museum, it is the intermediate form of ornamental colouring between D. Blocliii and D. pictnm, the two bands which pass backwards from the eye to the caudal tin become merged into one below the middle of the soft dorsal. Diaijmmma pidmn has the same ground colour as D. Blocliii with fewer but wider longitudinal bands : the first, second, and third bands coalesce much sooner, the upper two below the middle or end of the spinous dorsal, and the second and third on the nape : whilst the two bands which pass backwards from the eye to the caudal tin, and which coalesce in Dr. Jerdou's specimen below the middle of the soft dorsal, in the typical pictuia forai a single broad one by the amalgamation of them in their whole length from the eye to the tail. The tins are coloured as described for D. Blocliii, in short the immature appear to be generally coloured as in the typical D. pictuiit. Bleeker's figure of Plectorhynclim pimctatus is this species, the ornamental colouring being increased by the addition of some extra intermediate bands which are broken up into spots : the ventral and anal are likewise darker, due to the existence of additional colour. In a bad skin in the British Museum, marked D. Blocliii with D. J !i, all the longitudinal bands are liroken up into a series of elongated spots or blotches. Ha\-ing remarked how the wide bands in the tj-jiical B. pictum are liable to be varied by the existence of more numerous but narrower ones in D. Blocliii it remains to be observed that they may be further moditied by being broken up into rows of oblong blotches or spots ; or when narrow bands exist they may be alternately complete or interrupted as in D. pwcilopiterum. * Col. riayfair, Fish. Zanz. p. 28. appareiitly on the .authority of a single skin, asserts "the colour of the adult is dark grey, with darker longitudinal lines and series of spots ; tins blackish, except pectorals, which are grey." But as specimens with the colouring of the typical Blochii exist as large as tlie grey lineated one, I think it would be preferable to consider such as having a peculiar form of colouring. However, a doubt is raised as to whether Diagramma Blochii, Cuv. and Val.. is Anthias diarircimma. Bloch, .is he remarks " the younger specimen acrees perlectly with the AvtJiias diagramma of Bloch, although it is doubtful whether it is the same as the D. Blochii of Cmier and Valenciennes, which is only known from a figure taken at Triucomalee."

Ei/es — diameter from 2/9 to 1/4 of length of head, 1^ to 2 diameters from end of snout, and about 1 apart. Dorsal profile much more convex than that of the abtlomen. The maxilla reaches to below the hind nostril. Vertical border of preopercle serrated, as is also its rounded angle. Shoulder-bone serrated. Teeth — villiform. Fhis — dorsal spines moderately strong, the second and third being the longest and equal to two- fifths of the length of the head : second anal spine slightly the strongest but the third a little the longest : caudal Imiated : the distance the ventral fins extend varies considerably with the age of the fish, becoming comparatively very much shorter in the larger specimens. Colours — grepsh, several rows of large brilliant golden spots along the upper half of the body : three short bluish bands pass from the eye across the opercle, and two more in the same direction between the eye and the angle of the mouth, these bands are continued on to the body between the rows of spots. Two rows of brownish spots dashed with yellow exist on the hard dorsal as well as a light longitudinal band : soft dorsal with similar spots much wider than the ground colour : caudal the same : anal and ventral likewise spotted, the latter being greyish externally : pectoral golden. In a specimen 27| inches in length tlie colouring varied, it being of an uniform greyisli-bro-uTi, some small ill-defined spots on the soft dorsal : the caudal covered with small circular brown marks as well as the outer half of the anal : ventral externally greyish. Bleeker (Revis. Plector. p. 301) considers D. p'ctiim imd D. 2mncfatiim as the young and adult of one species, the colours and the foiin of the dorsal changing with age. My specimens however show D.

Enes— diameter 2/^5 to 1/3 (in the adult) of length of head, 2/3 of a diameter from end of snout, and 3/4 to 1 apart. The maxilla reaches to below the anterior fourth or in the adult to beneath the front edge of the orbit. Preorbital with rather a deep plate, armed superiorly with one strong fluted spine projecting backwards and from about three to seven or eight denticulations below it : above this spine the suborbital^ plate is armed wiijt another directed both forwards and backwards, in some specimens these are very small, especially the anterior one. In one specimen this anterior projection of the suborbital spine is imperceptible, so it is probable that Sir John Richardson's statement of " two suborbital teeth pointing backwards, one mider the other and more slender, none pointing forwards," may have been quite correct : it is scarcely necessary to observe that he considered the preorbital spine as a suborbital one. Preopercle with its vertical limb slightly emarginate, due to its projecting * Cuv. and Val. remark upon Russell's figure showing 10 soft rays in the dorsal fin, and his description giving 1 1, consequently a new name was bestowed on the species, which however only possesses 9 rays. t Cuv. and Val. bestowed this designation on Riippell's fish because the vertical limb of the preopercle is not shown so emarginate as figured by Rnssell and as existing in nature.

In the young, .S'. torquatus, the serrations are moderately coarse and directed backwards, sometimes a smalf cusp exists at the base of some, at other times it does not, the vertical limb and rounded angle may be said to be serrated, the serrations being directed backwards. As the size of the specimen augments, S. Japonkns, we find that these basal cusps begin to"be more distinctly developed, and a blmit one as a rule is present at the base of every serration, in some specimens the posteriorly directed teeth now begin to disappear. As the adiilt, S. auratus, is reached the appearance becomes remarkable, the posteriorly directed serrations on the vertical limb (not on the angle) have become absorbed, and the cusps at their bases have augmented in size and consequently the serrations project outwards instead of backwards. Operclo with a moderately developed spine. Teeth — generic, i^/xs— dorsal spines strong, each alternate one being broader, they increase in length to the fourth or fifth, from whence they continue "of about the same height, or equal to about half the length of the head, whilst the rays are of about the same height. Pectoral equal to the length of the head posterior to the nostrils : ventral almost reaching the anus. Anal spines strong, the third nearly equal to the highest in the dorsal fin but one-foui-th shorter than the second in a specimen 8| inches in length ; in younger specimens the dilference in length is sometimes not so gi-eat, in such cases the second spine is generally the longer, as will be alluded to: caudal forked. C'oZomcs— adult of a pale dull-red, usually having a whitish band round the opercles, from the upper edge of which bone a longitudinal wide line of the same coloui- passes backwards below the lateral-line, being lost beneath the end of the base of the dorsal fin. Every scale on the body has generally a dark basal mark. In the medium size fish, ,S'. Japonicus, the ground colour is often the same as given for the adult, but in others it is of an ashy grey : the opercular band is generally distinct and of a cream- yellow colour. A deep arterial blood-red spot exists behind the opercular spine, and the fins are of a pale yellow. In the young, 5'. tnrquatus, the band of the opercles is very distinct and of a light lemon-yellow colour, whilst the blood-red spot behind the opercular spine is very well marked : the inside of the mouth is likewise red. If we divide this fish into three distinct species merely in accordance with the colours observed,^ the difficulty arises amongst specimens from India, of ability to discover any very young S. auratus or S. Japonicus, unless the S. torquatus is admitted to be such. Of course, however, it is by no means improbable that some im- mature might from the first adopt the livery seen in the adult, but such a mere anomaly would be insuificient to constitute a valid species. In Cuvier and Valenciennes, it is observed that Ruppell's figure of S. kurite, does not show such an emargination of the preopercle as is exhibited in Russell's, this however appears to have been merely an accident. The question of the direction of the preopercular serrations deserves however more consideration, and it was not until I had collected a large number of specimens of all ages and examined those in the British and Madras JMuseums, that I arrived at the conviction that such were merely due to maturity or the reverse of the specimen. In the young, although the serrations project backwards, they have a small cusp at their base, which, did it gi-ow, would project outwards : in middle age tliis outer projection increases in development whilst the posterior one shows signs of atrophy : in the adidt stage the change is completed, the earliest serrations have become almost or entirely absorbed, the original basal cusp has developed mto an outwardly directed serration, having sometimes the original ones in the form of a backwardly projecting cusp at the base of each. . . , , p Bleeker, Z. c. places S. torquatus as nearly allied but distinct from S. Vosmeri, being distinguished from it by a more convex profile, a larger head, larsrer eyes and a lower anal fin. In colours by an absence of the hght lateral band and a purple triangular spot at the base of the pectoral fin. He gives in ,S'. torquatus length of head 4 to 4i, height of body 2| to 3 in the total length; eyes, diameter 2 to 2\ in the length of head: in the -S'. Vosmeri, length of head 4| to 4|, height of body 2f to 3 m the total length; eyes, diameter 2t to 3 m the length of head. PL xxiii, fig. I, represents a specimen of S. torquatus, life-size, no longitudinal band exists and the pectoral blotch is distinct, but the comparative length of the second anal spine is as great as in any specimen of the typical S. Vosmeri, which I have seen. In four other specimens 6, G^, 6^, and 7 inches respectively m length, the second anal spine is only 1/2 the length of the head. Therefore variations do exist, and to prove such I have figured (PI. xxiii, fig. 2) an intermediate form, 6^ inches in length, which agrees with Bleeker's torquatus. Hahitat.—ned Sea, East coast of Africa, seas of India to the ilalay Archipelago and beyond, attaimng at least 12 inches in length. 8. Scolopsis lencotEenia, Plate XXIII, fig. 4.

Preorbital one-third as high as the diameter of the eye, its spine weak, and tlie hind edge of the plate with a few indistinct serrations : suborbital ring of bones serrated. Vertical limb of preopercle slightly emargmate, serrated along its whole extent but most'eoarsely so at its rounded angle. Shoulder-bone serrated. Teeth— &ne.. FAMILY, I— PERCID^. 89 Fins — dorsal spines strong, increasing- in length to tlie fourth which equals half the length of the head : pectoral equals the length of the head without the snout : the ventral nearly reaches the anal : second anal spine much the strongest and consideralily the longest, equalling the length of the head behind the middle of the eye. Colours — a broad yellowish-white streak from above the eye to the upper edge of the free portion of the tail, it is margined both alaove and below with a dark purple stripe : above it the body is reddish-brown, below it yellowish : a dark purplish vertical baud extends down the opercle. Fins reddish, the dorsal with a fine black upper edge and a dark band along the centre of its spinous portion. In the typical S. leucoUeaia, no black mark exists on the dorsal fin, and the second anal spine is longer and stronger than the third. In S. leucotiBiiioides a black blotch exists between the first and fourth dorsal spines, and the second and third anal spines are of about equal length and strength. In the specimen figui-ed, a dark band passes along the spinous dorsal and the anal spines are as in 8. leucoUenia. Hahitat. — Bombay to the Malay Archipelago. My single specimen having its tail injured must be the excuse for the way in wluch I have given the proportions, but Bleeker observes, length of head 1/4, height of body 2/7 to 1/4 of the total length. 9.

A prominent ridge having a serrated edge exists on the maxilla, and that bone extends to below the front margin of the orbit. Preorbital with a strong spine directed backwards, two smaller ones on the plate below it and a few serrations beneath. Vertical edge of preopercle serrated, most strongly so at its angle which is not produced. A con- spicuous spine on the opercle : shoulder-bone serrated. Teeth — villiform. Fins — dorsal spines slender, increasing in length to the fifth, the height of which nearly equals half the length of the head : anal spines not strong, the third weaker but longer than the second, and nearly equalling the longest in the dorsal fin : caudal forked. Colours — greenish-olive above, becoming lighter on the abdomen : a silvery white band extends between the lateral-line and the back, from near tlie head to opposite the commencement of the soft dorsal : the position of this white line Bleeker observes is liable to change with age : the scales below the lateral-line have a golden spot. Fins reddish. Hahitat. — Andamans, Malay Archipelago, &.c. The specimen figured is 7 inches in length and from tho Andaman islands. Genus, 22 — Dentex, Cuv. Gymnocranius, pt. Klunz. : Paradentex, pt. Blkr. : Synagris, (Klein) Bleeker. BrancM'Ostecjals six or seven : pseudobrancMce. Body oblong, rather elongate, and a little elevated. Eyes of viedium or rather large size. Mouth moderately protractile, its cleft more or less horizontal : jaws of about equal length. Preopercle entire or feebly serrated : op/ercle without any or with a not very pronvinent spine : the distance between the eye and the angle of the mouth considerable. Generally strong canines from 4 to 6 Mt number in bothjaips, almost invariably present in the upper : a conical outer lateral roiu in either jatv : vomer, palate, and tongue edentu- lous. One scaleless dorsal fin having from 10 to 13 spines, anal with three and nine to eleven rays : the spines generally loeah, and being more or less providedj tvith a scaly groove: caudal forked. Scales ctenoid, of moderate size, more than three rows between the eye and the angle of the preopercle, none on the front of the snout, jaws, or preorbital. Air-vessel not constricted but notched posteriorly. Pyloric appendages few. This Genus has been subdivided from Synagris, mostly owing to the existence of upwards of three rows of scales across the preopercle. Even thus restricted it has been further subdivided and Q-ymnoaranius, Klunz. ^ Paradentex, Bleeker, consists of those species in which the scales do not extend forward on the upper surface of the head so far as the eye : none on the outer ILmb of the preopercle : the upper jaw is rather more protractile, and the canines are weaker. Geographical distribution. — The fishes of this Genus have a wide range, being found in the Mediterranean, Atlantic, Red Sea, and through those of India to the Malay Archipelago, and beyond.

Length of head 4^, of caudal (without its prolongation) 4|, height of body one-fourth of the total lengtli (excluding tlie prolonged caudal ray). Eyes — diameter Z\ in length of head, 1 diameter from end of snout, and 2/3 of a diameter apart. The height of the head equals its length exclusive of the opercle : lower jaw slightly the longer : the maxilla reaches to below the front edge of the orbit. Height of preorbital equals 2/3 of the diameter of the eye, it terminates posteriorly in a point below the last third of the eye. Vertical limb of preopercle finely and evenly serrated in its middle third, its angle rounded and entire. Opercle without any distinct spine. Teeth — villiform along the whole of the upper jaw, with 4 canine-like ones anteriorly in either premaxillary, laterally the outer row is composed of about 30 closely set conical ones : the inner ones in the mandiljle are villiform just above the symphysis, whilst laterally they are in two rows of which the inner is slightly the larger. Fins — dorsal spines rather weak, the two first elongated, the second reaching to the base of the caudal fin : interspinous membrane very slightly notched, the height of the last eight spines gradually increases, the last equalling rather more than the length of the postorbital portion of the head but is not so high as the rays. Pectoral as long as the head. Ventral reaches the anal. Third anal spine the longest, and equalling 1/3 of the length of the head. Caudal forked, upper lobe with a filamentous prolongation. Scales — extend forwards superiorly to between the eyes. Lateral-line — the tubes divide posteriorly into two branches. Colours — silvery, with pinkish longitudinal bands : fins pinkish stained with yellow. The specimen described and figured is from Sir W. Elliot's Madi-as collection, the coloured figui-e is named Deniex striatus C. V. by Jerdon, and is alluded to in M. J. L. and Sc. 1851, p. 134. This species, a specimen of which, from Vizagapatam, has been given me by Sir Walter Ellic*, cannot bo Spondyliosoma guliminda (C. V.) Cantor,* Catal. p. 60, which is not Russell's Sitarus lama guliminda— Synagris^ tolu, of which I have both male and female specimens. It is very similar to S. Japonims, but (irrespective of the spines being weaker and longer, it has only 9 instead of 10 rows of scales between the lateral-line and the base of the anal fin). I have a male of that species which has no prolongation of the dorsal fin. There are two of Bloch's specimens marked Detitex luteus at Berlin, one evidently the skin from which Bl. Schn.'s figure has been taken, the artist not having reversed it, whilst he has delineated the eye too small, and the (?) elongated dorsal spines are broken. On the second specimen, which has no elongated dorsal spine, is Val.'s label, " C'est le vi'ai G. lutea, Bl. Schn." Bloch's may be this species, but it has several rows of villiform teeth in the mandibles of about the same size and very similar to (S. Jaiwmciis, which it appears to resemble. This (Synaqris striates) is certainly Jerdon's Dentex striatus. ' Bl. Schn.'s figure is probably coloured from a description in which it was said to have been striated or banded, and instead of placing such longitudinally he has given them as vertical. Habitat. — Coromandel coast of India : the specimen figured was captured November 25th, 1852. Dentex filamentosus, C.V., came from Surinam. 2. Synagris tolu, Plate XXIII, fig. 6.

Length of head 2/9, of pectoral 1/6, of caudal 2/9 to 1/4, height of body 2/9 to 1/4 of the total length. Eyes — transversely oval, diameter 1/3 of length of head, 1 diameter from end of snout, and 2/3 apart. Jaws of equal length, the maxilla reaches to below the front edge of the orbit. The lower edge of the preorbital obliquely convex in its posterior half, its height equals half the diameter of the orbit. Preopercle entire. Opercle with a small flattened spine. Teeth — villiform along the whole of the upper jaw, with from 4 to (J canine-like ones anteriorly in either premaxillary, laterally the outer row is composed of about 16 closely set pointed ones : the inner ones in the mandible also villiform, opposite the symphysis in several rows, laterally in a single one, the outer row in front of the lower jaw is rather larger than the villiform ones, but not so large as the outer lateral row which equals those in the side of the upper jaw. Fins — dorsal spines very slender and flexible, the interspinous membrane deeply notched. The spines increase in length to the sixth, seventh, and eighth, which equal two-thirds the height of the body, the last spine equals two-fifths of the height of the body and is of the same length as the last ray : pectoral fin as long as the head excluding the snout : ventral with its outer ray elongated, scarcely reaches so far as the anus : second anal spine of equal strength to but not so long * In Cantor's fish the dentition is slightly difiTerent, it has villiform teeth in both jaws, with 5 or 6 small curved canines in the front of the upper jaw, whilst laterally its outer row is slightly enlarged : the canines in iront of the lower jaw are very small, whilst laterally the outer row is scarcely larj^er than tlie villiform teeth. N 2 92 ACANTHOPTERTGII. as the third wliicli equals one third of the height of the body : caudal deeply forked the upper lobe the longer. As regards sexes the dorsal sj)ine8 are equally prolonged in males and females : the pectoral is a little longer in tlie males, extending to the anus, but the caudal lolx;s are the same. Culuurs — rosy, with four or five yellowish longitudinal bands between the rows of scales from immediately above the base of the pectoral fin. Fins pinkish : tips of dorsal spines orange. Russell's figui-e, although defective, is sufficient to distinguish the species by : it is the most common kind in IMadras from October to March, and may be at once recognised fi'om the other recorded forms by its long and flexible dorsal spines and deeply emarginate interspinous membrane. The caudal fins of some males examined in October had no filamentous prolongations. Cuv. and Val. specimens are in good preservation at Paris and coincide with the above described, but not with Sponihjllosnma ijulimitula, Cantor, whose type is iu the British Museum. Habitat. — Seas of India to the Malay Archipelago. 3. Synagris Bleekeri, Plate XXIV, fig. 1. B. vi, D. V", P- 17, V. 1/5, A. f, C. 17, L. 1. 48, L. tr. 3^11. Length of head one-fourth to 2/9, of caudal 4f , height of body 4j in the total length. Eyes — transversely oval, diameter 3 J in the length of head, Ij diameters from end of snout, and 1 apart. Interorbital space flat. The maxilla reaches to below the first third of the orbit. Preorbital three-fourths as high as the leng-th of the transverse diameter of the orbit, its posterior margin oblique gradually passing into the inferior one. Preopercle entire. A small flat spine on the opercle. Teetli — in villiform bands in the upper jaw, four small canines in the front of each premaxillary, no enlarged lateral row : villii'orm teeth above the symphysis in the lower jaw, but continued a very short distance laterally, and canine-like teeth in front of the lower jaw, and a single row of conical ones in the last two-thirds of the mandible. Fins — dorsal spines of moderate strength with the interspinous membrane scarcely notched, the spines increase in length to the last, the height of which equals the length of the post-orbital portion of the head or two-fifths of the height of the body, the last rays somewhat elongated and equal to half the height of the body. Pectoral nearly as long as the head : ventral with its outer ray elongated and nearly reaching the anal spines : anal sjiines of equal strength, the second not so long as the third which is rather longer than the diameter of the orbit : caudal deeply forked, the upper lote the longer, but no filamentous prolongation was observed in Madras specimens. Golours — reddish superiorly, becoming silvery along the sides and beneath, where yellow bands exist : a bluish spot on the opercle : fins reddish, dorsal edged with orange and having a golden band along its base. This species is closely allied to S. notatus, from which it differs both in its dentition and colouring. Sahitat. — Seas of India. The specimen figured is from I\Iadras, and 8 inches in length. 4.

Eyes — diameter 3^ to 3j in length of head, Ij to H diametei's from end of snout, and nearly 1 apart. The maxilla reaches to below the fii'st third of the orbit. Vertical limb of preopercle finely and evenly serrated in its lower half : its angle rounded and entire. Opercle without any distinct sjjine. Teeth — ^in villiform bands in both jaws, from four to six small curved canines in the front of either premaxillary, whilst the outer row is a very little the largest : in the mandible the last six or eight teeth only are conical and a little enlarged. Fins — dorsal spines rather weak with the interspinous membi-ane scarcely notched, the height of the sj)ine8 increase to the last which equals the length of the postorbital portion of the head ; the last ray equals half the length of the head. Pectoral reaches to above the anal spines. Ventral, having its first ray prolonged, reaches as far as the anal fin. Third anal spine slightly weaker than the second but longer, equalling one-third the length of the head. Caudal deeply forked, having a filamentous prolongation. (This may be peculiar to the males, but I have reason to believe it is present in the females. In a specimen captured at Madras, 9^ inches in length to the end of the caudal lobes, the upper one is produced beyond this 2^^^ inches in addition.) Colcmrs — -yellowish-red, having longitudinal reddish lines along each row of scales. Dorsal and anal fins with a yellow streak along their centres, a grey base and pinkish edge. Dentex Blochii, Bleeker (Sciten. p. 17(3, and Revis. Dentex, p. 27)^=Sy>iagris Japonicus, Giinther (Catal. i, p. 378) is not synonymous with the above, its preopercular limb being entire. The statement in Cuv. and Val. of the preopercular edge being entire is erroneous, as I have convinced myself by examining the type specimen at Berlin, and Val.'s identification of it with Sparus Japonicus was perfectly correct. S. grammicus ajipears to be a variety of this fi.sh, its preorbital being considerably higher than is seen in FAMILY, I— PERCID^. 93 specimens from the Red Sea and East coast of Africa, in the former the height equalling almost 1 diameter of the orbit ; in the latter 1/2 or 2/3 of a diameter. Habitat. — Red Sea, East coast of Africa, and seas of India. 5. Synagris notatus, Plate XXIV, fig. 3. ? Dentex furcosus, Cuv. and Val. vi, p. 244. Synagris furcostts, Gunther, Catal. i, p. 373.

Length of head 3| to one-fourth, of caudal 2/9 to one-fifth, height of body one-fourth of the total length. Eyes — diameter 3| to 1/4 in the length of head, \\ diameters from the end of snout, and nearly 1 apart. Height of the head nearly equals its length. The maxilla reaches to below the front edge of the orbit. Preorbital under the commencement of the eye is nearly as high as the transverse diameter of the orbit, whilst its hind edge is more angular than in S. lileekeri. Preopercle entire. Opercle with a small flat spine. Teeth — villiform in the upper jaw with four large curved canines in either premaxillary, and laterally an outer conical row which are not very large : villiform ones in the front third of the lower jaw with sis well-developed anterior canine- like ones, laterally a row of conical teeth which become small in the last fourth of the jaw. Fins — dorsal spines weak, interspinous membrane very slightly emai'ginate, the spines increase in length to the fifth from whence they continue of about the same height or 1/3 of the length of the head to the last which is a little longer being 2j in the same distance : the length of the last rays equal that of the postorbital portion of the head. Pectoral equals 3/4 of the height of the body. Caudal forked, upper lobe the longer. Colours — rosy with a brilliant spot on the first five scales below the lateral-line, the upper half red, the lower yellow. Five or six longitudinal j-ellow bands are present below the lateral-line, and three sUvery-whitc ones : fins pinkish, with a yellow band along the bases of the dorsal and anal. This appears to be a slight variety of S. furcosus, Giinther, in which latter the dorsal spines increase in length to the third from whence they slightly decrease to the last which equals the length of the head behind the eye. Dentex furcosus, C. V. has an elongated body and the caudal lobes very prolonged. Halitat. — Seas of India. Genus, 24 — Pentapus, Cuv. Leiopsis, Bennett : Gnatlwdentex, pt. Bleeker.

Branchiostegals six : pseudobraiichice. Body elevated or oblong, and compressed. Mouth very protractile and descending when produced. Preopercle as a rule entire, rarely serrated. Eyes comparatively large. Villiform teeth in the jaws. Inferior piharyngeal hones firmly united by a suture. Length of the bases of the spinous atul soft portions of the dorsal fin of nearly equal extent, and having a scaly sheath into which it can be wholly or partially received : the spines numbering nine or ten, the rays ten or eleven : anal ivith three spines : caudal forked. Scales of moderate size, when ctenoid very slightly so. Air-vessel simple. Pyloric appendages feio. Gill places the Gerrini as a distinct family. Geographical distribution. — All the tropical seas, entering estuaries. Some apparently being mostly confined to the latter situations, and ascending into brackish or fresh waters as high as tidal influence extends. Uses. — As food these fishes are mostly eaten by the indigent classes, being little esteemed whilst fresh on account of their numerous bones and deficiency in flavour. As they salt and diy well, large numbers are extensively prepared in this manner for future use or as a matter of export trade. The species comprising this genus are somewhat dilEcult of determination unless a good collection is brought together, but even then some important considerations have to be borne in mind prior to deciding whether the specimen belongs to a known or an unknown species. The eye, certainly in some, increases in FAillLT, I— PERCID^. 97 comparative size -witli the head as age advances, as occurs in MegnJops cyprinoides, &c. The first few dorsal spines may be compressed or rounded : and the second and third slightly or very elongate, but this elongation often varies considerablj', as seen in G. filamentosus, in vv'liich it may be only two-thirds the height of the body or even extending so far as the base of the caudal fin, and though this diii'erence is generally, it is not always due to age, but in the young it is mostly shorter than in the adult. Even in the anal spines the second may be equal in length to the third or a little longer or shorter in the same species. As regards colour the young are generally vertically banded, and these bands may be indistinct or even entirely absent in the adult. In those with longitudinal bands they sometimes become interrupted in large specimens, showing rows of long oval blotches or marks placed one over the other, the reason usually being that these marks are apparent in the adult where the vertical bands existed in the immature.

Hamilton Buchanan states that Chanda setifer has ten prickles in its dorsal fin, the first of which is very short ; but irrespective of his description he has left a drawing of it, labelled hatclianda, whilst amongst the collection of fishes received by the British Museum from Mr. Waterhouse exists one, the type of Gcrres altispinis, Giinther, having ten dorsal spines, not nine as stated in the Catalogue. It is closely allied to G. lucidus, but possesses one more dorsal spine, a more or less serrated border along the horizontal edge of the preopercle, and one more row of scales between the lateral-line and the base of the dorsal fin.

Free portion of the tail as high at its commencement as it is long. Scales— the .sheath for the dorsal fin is rather more developed than that for the anal : a few scales over the caudal : four rows between the lateral-line and the base of the fourth dorsal spine. CofoMrs— silvery, with an indistinct'vertical dark band over the nape, a second from below the dorsal spines, and two more below the soft portion of the dorsal fin : snout black : fins canary-yellow, the upper half of the membrane between the second and fifth dorsal spines deep black, + the rest of the fin dark edged with a black margin : a row of dark spots along the dorsal spines and rays at half their height : caudal grey-edged; the inferior caudal lobe with a very narrow white lower edge and a white tip. As this fish increases in length the height of the body becomes proportionately a little less, thus at .5 inches in length it is 4/13 of the total : and the eye 3/4 of a diameter from the end of the snout._ This sfiecies is closely allied to G. seti'fer, but the latter appears to be confined to the tidal Hooghly, whereas this is a marine form having one dorsal spine less, &c., as already pointed out (see p. 98). _ _ _ _ Habitat.— Seas of India to the'Malay Ai-chipelago and China : it is the most common Indian species, visiting the coasts in enormous numbers. 6.

Body of a long oval shape : dorsal and anal profiles equally convex. Snout slightly swollen. The posterior process of the premasillary reaches to opposite the first third of the eye. No spines or serrations around the orbit. The maxilla reaches to below the front edge of the eye. Mandible not concave inferiorly. Lower preopercular edge serrated. Teeth — villiform in the jaws, vomer and palate edentulous. Fins — dorsal spines weak, the first very short, the second one-third the height of the third which equals 4/7 of the length of the head. Pectoral equals the height of the body. _ Ventral reaches two-thirds of the distance to the anal. Second anal spine the longest and equal to 1/3 of the height of the body : caudal forked, upper lobe the longer. Free portion of tail rather higher than it is long. Sca,les very deciduous, they extend forwards over the back to opposite the middle of the eyes. Colo^irs — silvery, with a silvery stripe from the eye to the base of the caudal fin. Cantor erroneously gave 4 spines instead of 5 to the anal fin, in this he appears to have been copied by Dr. Giinther. The specimen is much mutilated but 5 spines are still visible. On mentioning this fish to Dr. Bleeker he at once showed me his types of Pentaprion rjerroides, which are identical. Habitat. — Madras, where I procured several specimens, to the Malay Archipelago. Cantor observes that " in the Straits of Malacca this species is very abundant at all seasons, and quantities, both fresh and di-ied, are consumed by the natives." ADDENDA AND CORRIGENDA. Page 18.

Body elevated and compressed. Eyes lateral and of moderate size. Mouth generally small, with a lateral cleft, and situated in front of snout. Teeth villiform or setiform, neither incisors nor canines : in most of the genera the palate is edentulous, soft portion of the dorsal fin of greater extent than the spinous, sometimes considerably more, rarely slightly so ; anal with three or four spines, its soft portion similar to that of the dorsal : lower pectoral rays branched : ventrals thoracic, with one spine and five rays. Scales cycloid, or very finely ctenoid, extending to a greater or less extent over the vertical fins, but occasionally absent from the spinous portion. Air-vessel present, generally simple. Intestines usually much convoluted ; stomach caecal. Pyloric appen- dages in moderate numbers. Geographical distribution. — These fishes are, as a rule, marine, and although some have been recorded as taken in rivers and estuaries, they are rarely captured above tidal reach. The Squa.mipinnes have been divided by Dr. Giinther into three groups : — First, those which have the palate edentulous {Chaiodontina') : secondly, those which have teeth on the jialate, but the dorsal fin is .situated in the posterior half of the length of the back {Toxotina') : and thirdly, some Australian forms wherein there are palatine teeth, and the dorsal fin occupies the middle of the length of the back, (Scorpidina) . In some species a prolongation of the dorsal fin, owing to sex, may be present as in Holacantlms impei-ator, E. annularis, &c. SYNOPSIS OF GENEEA. First group — Chstodontina. No palatine or vomerine teeth : no concealed spine in front of the base of the dorsal fin in the adult. 1. Chaiodon. Snout of moderate length or short : no preopercular spine: a single un-notched dorsal fin without an elongated spine : anal with 3 or 4 spines. 2. Chelmo. Snout much produced : no jireopercular spine : 9 to 13 dorsal spines none of which are elongated. 3. Eenioclms. Snout of moderate length : no preopercular spine : 11 to 13 dorsal spines, the fourth being m.uch elongated. 4. Zanclus. Snout of moderate length : no preopercular spine : 7 dorsal spines, the third being much elongated. 5. Holacanthus. Snout of moderate length : a strong preopercular spine : 11 to 1.5 dorsal spines, none of which are elongate. 6. Scutr/pharjus. Snout of moderate length : no preopercular spine : dorsal fin notched and no scales on the spinous portion : anal with 4 sjaines. 7. Epjhippus. Snout short : no preopercular spine ; dorsal fin deeply notched, with 8 or 9 spines several of which are elongated and flexible. 8. Ilrcpane. Snout short : no preopercular spine : dorsal fin deeply notched, with 8 or 9 spines, none of which are elongated. Second group — Toxotina. Vomerine and palatine teeth : no concealed spine in front of the base of the dorsal fin which is situated in the last half of the back. 9. Toxotes. Snout somewhat produced. Dorsal fin with 4 or 5 spines. The young fishes in some of the above genera of the first group show considerable enlargement of the bones of the head which more or less disappear in the adult,* in a few a concealed spine pointing forwards may be present in the immature in front of the base of the dorsal fin. * Genus — Tuolichthts, GUnther. Dr. Giinther (Annals and Mag. of Nat. History, 1868, p. 457) described and figured a very small fish, II millLms. long, as a new Cyttoid Genus, which he termed Tliolichthys. I obtained several (I think thirteen) larger ones at Madr-as lyV inches long, which I described (Proc. Zool. Soc. 1870, p. 687,) as T. osseus, but drew attention to their belonging to the Family Squamipinnes, giving it a strong resemblance to Ueniochus or Chcetodon. I personally deposited my largest specimen in the British Museum, but as it has been mislaid I have figured my next largest at twice the natural size ; it is unfortunately dried, all my specimens in spirit, irrespective of the one previously mentioned, having become spoiled during their transit from India.

Fins — dorsal spines of moderate strength, the last being the longest, the soft portion of the fin rounded : candal cut almost square : ventral reaching as far as the anal spines : pectoral equal to the length of the head behind the angle of the mouth : second anal spine strongest and rather the longest, being equal to the last of the dorsal fin. Colours — body and head of a rather red-lilac-purple, becoming of a primrose colour posteriorly, and also on the fins. A dark ocular band, narrower than the orbit, commences a short distance anterior to the dorsal fin, and is continued through the eye on to the interopercle, it has a white edge. A black band, widest above, arises 6-om the first four- or five dorsal spines, and is continued to a short distance below the lateral-Hne :* a second angularly pointed in front, begins from the last thi'ee spines and descends to the lateral-line : a third passes over a free portion of the tail. Twelve to fourteen vertical narrow black bands pass down either side. Soft dorsal fin with a narrow black upper margin : caudal with a black and white posterior edge : anal with a black intramarginal band having a white outer margin, and two more superiorly parallel to it. Habitat. — Seas of India to the Malay Archipelago and beyond. The specimen figured was taken at the Nicobars, the species attains to at least 8 inches in length. * A different distribution of colours is shown in Garrett's " Fische d. Sudsee," in which the body is lighter than described above. The two dark vertical bands from the dorsal fin are conjoined superiorly and only extend forwards so far as the fourth dorsal spine, but they descend lower than in my specimen. Likewise the band over the free portion of the tail is reduced to a blotch. The body bands are stated to have sometimes white edges. FAIHLY, 11— SQUAmPINNES. 105 4.

Caudal white, with or without a narrow black outer margin. In a specimen in my collection thl^re are reticulated blue lines between the broad white band behind the eye and on one desce'ndino- from the centre of the spinous dorsal. In the adult (H. semicirculatus) the vertical bands have a more curv'ed direction, the convexity being forwards. In the Nicohariensis this is still more apparent, a white spot or short transverse band being the centre around which the body bands are curved. In both these last varieties the tail fin is coloured. _ ...

We are informed that they were originally termed Mullus by the Romans, vfith reference to the scarlet colour of the sandals that theii' Consuls wore, and which were subsequently adopted by their Emperors under the designation of Mullens. These fish kept in vivaria did not increase in size. The liver was considered the most delicate portion of the Red Mullets, which are now frequently termed the "Woodcock of the seas," due, it is asserted, to the fact that they are di-essed similarly to those birds. SYNOPSIS OF GENERA. 1. JJpeneoides. — Teeth in both jaws, on the vomer, and palatine bones. Red Sea, East coast of Africa, seas of India, to the Malay Archipelago and beyond. 2.

Mediter- ranean and temperate parts of Europe. Amongst these fishes a minute first spine to the dorsal fin appears to be sometimes wanting ; in other instances, where it is of a larger size, it seems rarely to be absent. There are likewise several other points that should not be overlooked. The comparative length of the barbels appears liable to increase with age ; sometimes a sharp spine exists at the shoulder in the young, mostly disappearing as the adult stage is arrived at, although in such it may remain or even be present on one side and absent on the other, as a rule it atrophies into a blunt point. The preorbital may be scaled or scaleless. In the " Fishes of Zanzibar," 1866, Messrs. Giinther and Playfair reunited all the genera into that of Mullus (p. 40). Dr. Giinther observed in the " Zoological Record" for 1865, p. 183 : " The Recorder regrets to have formerly adopted the genera proposed in this family by Bleeker * * the Recorder regards the MulUdce as one natural genus." However, in Garrett's " Fische d. Sudsee," 1874, Dr. Giinther still retains Bleeker's genera, and they appear to have been generally adopted by other Ichthyologists as based on distinct anatomical characters. Still it does not seem superfluous to suggest that specimens of the genus JJpeneoides may be taken in the Indian seas with a more or less edentulous vomer and palate. Dr. Bleeker however changes his nomenclature in revising this family in 1874, considering the genus he formerly termed as TJpeneoides = Upeneus, Cuv. and Val. thus cancelling JJpieneoides : Mulloides he retains, but includes all bis other fish of this family under the generic term Pampeueus, chiefly characterised by a single row of conical teeth in both jaws ; vomer, and palate edentulous. Scales along the median line of the abdomen^ having an obtuse keel. Dorsal and anal fins scaleless. Genus, 1 — Upeneoides, Bleeher. Megalepis, Bianc. ; TJpeneus, sp. Cuv. ; TJpeneus, (C. V.)

Lateral-line— ^-iih several short bifurcations posteriorly. Free portion of tad l-i4 ACAXTHOPTERTGII. longer tlian higli at its commencement. Colours — a black band passes from the snout througli the eye, at first just below the lateral-line, subsequently upon it, and ending below the end of the soft dorsal, it is li scales in depth at its widest part : a black blotch at the base of the caudal fin, these two marks are divided by a light i)bH(|ue vertical band which passes over the free portion of the tail just behind the second dorsal fin : some golden spots exist on the scales along the sides of the body. A purplish stripe goes from the eye to the snout. First dorsal violet, second dorsal with a deep black baud along its base, it has several irregular transverse lines along its upper half : pectoral with a dark base : ventral blackish externally, reticulated internally : anal with narrow transverse lines as in the upper half of the soft dorsal, but of a violet colour : caudal with a black edging. A specimen in the Calcutta ]\Iuseum has on it an old label with Apogon Amherstinus. It was probably brought from Amherst by Blyth, but I am unable to find any record of the name having been published.

The maxilla reaches to neai'ly midway between the end of the snout and the front edge of the eye. Opercular spine rather strong. Barbels reach to rather beyond the vertical from the angle of the preoperclo. Teeth — in a single row of moderately sized ones in the jaws. Fins — first spine of dorsal fin very short, the third, sometimes also the foui-th, the highest and equalling the length of the head m front of the hind edge of the orbit, in a large specimen rather more, and about twice the height of anterior dorsal rays : second dorsal fin not having its last rays prolonged : pectoral nearly as long as the longest dorsal spine and equal to the ventral : caudal forked. Scales — finely ctenoid, present on snout and cheeks but none on the preorbital bone. Three rows between the two dorsal fins, and two entire ones between the lateral-line and bases of the dorsal fins. Lateral-line— iuhyAes with several rather long bifurcations posteriorly. Free portion of tail longer than high at its base. Colours — a black band passes fi-om the eye along the lateral-line and from below the middle of the second dorsal it becomes above that line ending 2/3 of a scale above it below the end of the second dorsal : a round black spot at the root of the caudal. In some specimens there is a darkish band along the dorsal fins. The similarity between this species and U. macronemus is so great that I have not considered it necessary to figure both. In TJ. barherinus the bands, especially on the fins, are much hghtcr, and the last dorsal and anal rays not _ elongated as in JI. macronemus. Both are abundant at the Andamans, and I would suggest an examination of their sexes and the number of crecal appendages in either sex.

JEJ^/es— diameter 1/5 to 1/6 of length of Jiead, dh diameters from end of snout, and l^ apart. Intcrorbital space very convex, no open pores on_ preorbital bone. The maxilla, which is very broad posteriorly, reaches a little above half way to below the orbit. Barbels extend 1 diameter of the orbit behind the posterior edge of the preopercle. Teeth — in a single conical row in the jaws. F(»s— first spine of dorsal minute, third the longest and equal to the length of the head in front of the middle of the eye, and twice as high as the anterior dorsal i-ays : three rows of scales between the bases of the two dorsal fins. Pectoral as long as the head anterior to the hind edge of the eye : anal commences on the vertical below the tliird or fourth dorsal ray, it is usually longer at its base than it is high, but in a beautiful figui-e of this species in Bleeker's Madagascar, 1. c. the "last "dorsal ray is elongated: ventral reaches the anus : caudal forked.

Lateral-line — tubes arborescent posteriorly. Free portion of tail somewhat longer than it is high at its base. Colours — purplish, a black horizontal band usually exists on the snout, and is continued through the eye sometimes to a good distance behind it. Two or three wide black bands descend from the two dorsal tins or the interspace between rA]\nLT, III— MULLID^. 125 tliem to the middle of the body, their number may be decreased by their amalgamating into one, or increased by their being split up into several. There is usually a third band over the free portion of the tail or a spot on the side of its base. Second dorsal, anal, and sometimes the outer half of the ventral finely banded, occasionally a dark basal band exists on the second dorsal.

Length of head 1/4, of caudal 1/5, height of body 1/4 of the total length. Eyes — diameter 6| in the length of the head, 3| diameters from the end of snont, and If apart. Height of head nearly equals its length. Interorbital space a little convex : the profile from the snout to the base of the first dorsal fin is in a moderate and even curve. No open pores on the preorbital. The maxilla reaches to about midway between the snout and the hind margin of the orbit. Barbels with roughened elevations along their whole length and extending to a little behind the posterior edge of the preopercle. Opercular spine of moderate size, teeth — a single row of conical ones in either jaw. Fins — first spine of dorsal minute, the third and fourth the longest and equal to li in the height of the body and nearly twice as high as the anterior dorsal rays : three rows of scales between the bases of the two dorsal fins : pectoral three-fourths as long as the head : caudal deeply forked, the lobes pointed. Scales — ctenoid, present on snout, maxilla and cheeks, none on the preorbital bone. Two entire rows between the lateral-line and the bases of the dorsal fins. Lateral-line — the branches of the tubes very- short but numerous. Free portion of tail rather longer than high at its base. Colours — reddish, the edges of the scales somewhat the darkest. A broad purplish band, having a light yellow edge on either side, goes from^ below and in front of the eye to the snout : the lower band is continued backwards across the upper edge of the opercle where it joins another from the lower edge of the eye : a third narrow yellow band goes from the upper edge of the eye backwards. Outer edge of preopercle purplish. The centre of each scale on the body, except the first thirteen of the lateral-line, has a golden spot : abdomen yellowish. Second dorsal and anal with from three to five bluish longitudinal lines. This species very nearly resembles the figure of 17. Ylamiiujii, C. V. iii, pi. 71, but has its second dorsal much lower. Habitat. — East coast of Africa and seas of India, attaining at least a foot in length. Specimen 12 inches long. 5. Upeneus displurus, Plate XXXI, fig. 3, Mullus displurus, Playfair, Fish.

Length of head 3f to aknost 1/4, of caudal 1/5, height of body 2/9 to 4f in the total length. Eyes— diameter 3/14 to 1/5 of length of head, 1| to 1| in the postorbital portion of the head, 2^ to 2| from end of snont, and l} apart. Snont pointed, compressed. The maxiUa reaches to rather more than half way below the front edge of the orbit. Barbels extend to below the hind margin of the preopercle. Interorbital space slightly convex : opercular spine of moderate strength. Fins — foui-th dorsal spine rather the longest and equal to three-fourths of the height of the body below it : three rows of scales between the two dorsal fins : front portion of the second dorsal equals two-thirds the height of the first dorsal : pectoral as long as the head anterior to the hind edge of the orbit : anal commences slightly behind the origin of the second dorsal : caudal deeply forked and the lobes pointed. Scales — on snout and head including most of the preorbital bone : the uncovered portion has some rather large pores. Colours — reddish, the edges of the scales being slightly darkest. A broad purplish band, having a light silvery edge, passes from in fi-ont of the eye to the snout : two more narrow silvery lines, formed of short oblong spots, proceed from hind edge of orbit for a_ short distance : the two rows above the lateral-line, and generally -the three below, have a golden-yellow spot in the centre of each scale : a light golden band over the free portion of the tail. First dorsal marbled wdth brown, the second with four and the anal with three reddish bands : caudal reticulated with light grey markings. Specimens from the East coast of Afi'ica are said to have two shining light longitudinal bands, the fii-st from^ the orbit to the middle of the soft dorsal, and the second, which is broader, from the upper lip to the middle of the back. Some confusion appears to have occurred respecting Colonel Playfair's two species, the markings stated to exist on the fins of pleiirotmua are shown on those of dispilurm by the artist. In the type specimens I am unable to trace any spots on the fins, whilst the two shining longitudinal bands are very distinct, but they are also slightly apparent in the large specimen. Also the dark band over the tail is present in the smaller specimens as well as in the large one. The situation of the eyes as shown by the artist appear to me to be correct although at vai'iance with the text. 126 ACANTHOPTERYGn. If tlio foreo-omc species are merely to be recognised hj tlieir markings, then the one I procured in Sind, where it is abundantf can hardly be more than another form of colouring, consequently those who hold the disnlums ami pleurofoe'nia to be distinct, would probably consider this as a separate species. Hahifat.— Sind, where it attains at least i'i mches m length, probably also found m East Africa, The specimen figured is 8| inches long. 6. Upeneus Indicus, Plato XXXI, fig. 4.

Scales finely ctenoid, extending on the head as far forwards as the snout, but none on the preorbital bone : two entii-e rows between the lateral-line and the bases of either dorsal fins. Free portion of the tail longer than high at its commencement. Lateral-line — tubes becoming very arborescent posteriorly. Air-vessel — present. Colours purplish-red, with a large oval shining golden blotch on the lateral-line opposite the interspace between the two dorsal fins, which usually disappears after death ; a purplish-black mark, lightest in its centre, on either side of the free portion of the tail between the end of the dorsal and the base of the caudal fins : yeUow lines or spots on the abdomen.

L. and Se. 1851, p. 140 : " this very beautiful fish is rarely met with at Madras": Russell also made much the same remark — however, I have frequently obtained it there. . The species I considered U. spiilurus from the Andamans 1 find to be U. Indicus : the U. Malaharicus has been considered to differ in wanting the spine to the anal fin and thus having only seven rays.

FAMILY, IV— NANDID^. 127 Family, IV— NANDID^, Gimther. Pseudochromides, pt., et Moenoidei, pt. Mtill. & Trosch. Branchiostegals from five to six : pseudobranchisB present in marine genera, but sometimes concealed or absent in those of the fresh-water. Body oblong and compressed. Teeth feeble, but dentition more or less complete. Dorsal fin single : the length of the base of the spinous portion of greater or equal extent to that of the soft : anal with three spines, its rays similar to those of the dorsal : ventrals thoracic, with one spine and four or five rays. Scales ctenoid, covering the body. Lateral line interrupted or absent. No super-branchial organ. Air-vessel present. Pyloric appendages few or absent. Dr. Giinther's family Nandidce is composed of three groups, his Nandina being similar to Nandoldes, Bleeker, containing the Genera Nandus, C.V., Badis, Bleeker, and Pristolepis, Jerdon=Cato2mi, Bleeker, wHcli Bleeker' observes belong to the great Family Percidce* Thus restricted, this small group would find a natural place between the Centrarchmi (Gnjstina, pt.) and the Ospkromenoides (LahyrinthibranchU) and the Pohjcentroides. It also approaches the Psewdochromidoides and the Cichloides. The dentition inside its mouth distmguishes it from the groups enumerated. Geographical distriUitim.—Oi the Asiatic Genera of Family Nandkke, Giinther, some are marine, others fresh-water fishes, extending their range from the Red Sea and East coast of Africa, through those of India, the Malay Archipelago and beyond. The colours in some are liable to considerable variations, due to age, probably season, and the locality they inhabit. The number of spines, rays, and even scales, as in the indigenous fresh- water Acanthopterygian genera, Amhassis, Anabas, Polyacanthus and Trkhogaster are by no means fixed, a few more or less being of no uifrequent occurrence. The same remark applies to the serrations of the bones of the head as they often vary m specimens from different parts, which however can merely aUow their being classed as local varieties and not distinct species.

Length of head 2/9 to 1/5, of pectoral 1/5, of caudal 2/9, height of body 2| to 2/9, in the jariety figured, in the total length. Form of body an elongated oval, sides compressed, i^z/es— diameter 3f (3/11) of the length of head, 2/3 of a diameter from end of snout, and 1 apart. The maxilla reaches to below the front edge of the orbit : lower jaw slightly the longer. Teef/i— viUiform in jaws, vomer and palatines, also on pre-sphenoid and epi-hyal. Fins— sjiines somewhat slender, the soft portion of the fin rather elevated and pointed : anal spines short, its soft, portion similar to that of the dorsal : caudal pointed. Variations, as in other Acanthopte- rygian fresh-water fishes, exist in the number of spines and rays ; in Bengal and Madi-as the formula is generally D.

FMIILY, IV— NANDID^E. 129 Scales — ctenoid, extending over the body and head, there are two or three small rows along the bases of the dorsal and anal fins, and some minute ones are often present on the rays of the vertical fins, one entire row exists between the highest portion of the lateral-line and the small scales along the base of the dorsal fin. Lateral-line — interrupted below the posterior extremity of the dorsal fin. Air-vessel— large, with thin walls. Colotus — subject to great variation. In India proper, including the Punjab and Sind, the body is variegated with alternate belts of black and gi-een; but in old fishes, especially if captured in dii-ty water, these bauds are black and dirty red. On each shoulder there is usually a bluish-black spot, another is often present on the opercle, and a third at the base of the caudal fin. In specimens from Assam and Burma a different mode of colouring obtains. In Assam, in the variety figured, they are of a dull red, blotched or spotted with black ; but in Burma these spots take the form of six vertical bands, each being formed by four transverse blotches one above the other ; a large one is situated on the shoulder, and another on the side of the free portion of the tail : all the vertical fins have a narrow white edge.

SYNOPSIS OF INDIVIDUAL SPECIES. 1. Nandus marmoratus, D. \-}:{i, A. y^g-, L. 1. 46-57. Brown, vertically marbled with wide darker bands. This species shows great variation in accordance with the localities where it is taken, the^ serrations on the bones of the head being usually exceedingly indistinct or even absent in specimens obtained in Sind and India as far as Calcutta. But in Assam a considerable difi'erence is perceptible, as most of the specimens have both limbs of the preopercle and also the lower edges of the sub- and inter-opercles sen-ated, sometimes rather coarsely so. 1.

Dr. Jerdon felt so satisfied that the fish he described was the Gatopra Malahnnm, Giinther, and I obtained so many specimens from Malabar, all but one however with merely three anal spines, that I accepted his opmion that a misprint had occurred. The two original specimens of tetracanthus are in the British Museum, having been received without any indication of their habitat from the E. I. Museum, it is therefore open to enquiry whether they might not be Jerdon's types. This fish is said to attain a considerably larger size than 4 inches m length. 2.

Geographical distribution. — Red Sea, coasts of Africa, seas of India to the Malay Archipelago and beyond. Some stress has been laid in the discrimination of species in this genus as to whether the lower edge of the preorbital is straight or notched, in order to receive the posterior extremity of the maxillary bone. This sign however is of little if any value, for it may be straight, emarginate or deeply notched in the same species, as seen in C. berda, &c. The proportionate height of the preorbital to the diameter of the orbit varies with age, and its depth appears, as a rule, to increase, while that of the eye decreases, in comjjarison to the length of the head. Likewise, as is also the case in some other Genera, as Pristipoma, having the alternate dorsal spines broad on one side and not on the other, — it is not an invariable rule that the broad side shall be the first, third, fifth, and so on, for in specimens of the same species they may be the second, fourth, sixth, &c. The length of the second anal spine is subject to considerable differences, see C. Cuvieri, whilst the number of dorsal spines likewise varies. SYNOPSIS OF SPECIES. 1.

Eyes — diameter 1/4 to 1/5 of length of head, 1 to li diameter from end of snout, and also apart. A slight protuberance above the anterior-superior angle of the orbit. Dorsal profile considerably elevated. Preorbital twice as long as deep, its lower edge usually almost straight, but occasionally notched. In a large specimen in the British Sluseum it is cmarginate in the last three-fourths of its lower edge. The maxilla reaches to below the middle of the orbit. Vertical limb of preopercle very finely serrated : opercle with a well developed spine. Teeth — six incisors in front of either jaw, more closely set and less pointed than in G. Cuvieri, and with rounded teeth behind them ; an outer comjDressed row, (neither so large or pointed as in the last species, and blunted in the adult.) extending for only fom- or five teeth, exists in either jaw, internal to which are three or four rows of rounded molars in the lower and four or five in the upper jaw : the inner teeth of the hind rows are the largest : there are no villiform teeth in either jaw. Fins — alternate dorsal spines strongest on one side, the fourth being the longest, and as long as the postorbital portion of the head : first anal spine short, the second as long as the head excluding the snout. Lateral-line — 3^ rows of scales between it and the sixth dorsal spine, 10 rows between the base of the ventral fin and the lateral-line. Colours — silvery-gi-ey, the bases of the scales darkest and their edges silvery, this is most distinct above the lateral-line : a dark interorbital band : dorsal and caudal with black edges, a dark band along the soft dorsal and the first few anal rays. Dr. Giinther (Catal. i, p. 490) considers C. xanthopioda and C. anripies, Richardson, synonyms of this species. It differs from C. henla in its teeth, likewise in the strength of the dorsal spines, the mimbcr of pyloric appendages, and also of the rows of scales. Habitat. — The specimen figured (6 inches long) is from the Hooghly at Calcutta, where it attains at least 18 inches in length. It is found from the Red Sea throughout those of India to the Malay Archipelago and beyond. 2. Chrysophrys berda, Plate XXXIV, fig. 2, and XXXV, fig. 2 (var. calamara.)

Eyes — diameter 2/7 to 1/4 of length of head (in a young specimen 4^ inches long 1/3), Ij to \\ diameters from end of snout, and also apart. Dorsal profile more coun ex than that of the abdomen, snout compressed and somewhat pointed. The maxilla reaches to below or slightly behind the front edge of the orbit. Preorbital narrow with its lowur edge straight, emarginate or even notched above the end of the maxilla. Vertical limb of preopercle a little roughened or even minutely serrated : opercle with a distinct spine. Teeth — six incisors in front of either jaw, the remainder of the teeth with rounded crowns except a few in the outer row of the npper jaw, which are occasionally not so obtuse as the others: three or four rows in the lower jaw, four or five in the upper, the largest being the last of the inner series. Fins — each alternate dorsal spine strongest on one side, the fourth or fifth being slightly ,the longest and equalling from about 1/2 to 2/3 the length of the head. Pectoral slightly longer than the head. Ventral not reaching the anus. Second anal spine much the strongest equalling from 1/2 or a little more (in typical berda) to 3/4 of the length of the head (in the variety calamara), in which last it is much the strongest : caudal emarginate. Scales— ionv entire and two half rows between the lateral- line and the base of the spinous dorsal : nine rows between the base of the ventral and the lateral-line. Air- vessel — notched posteriorly. Colours — in berda silvery-grey. Scales darkest at their bases and usually a black spot behind the opercle on the shoulder. A black edge to the dorsal interspinous membrane, soft dorsal, caudal, and anal with black edges : a dark band along the anal fin. In specimens from Sind browiush bands usually radiate from the eye. In the variety calamara the fish is dark-greyish, the scales with dark edges, the tins black or edged with black. Some specimens are much darker than others. Valenciennes vi, p. 115, observes that he has compared Spiarus hasta, Bl. Schn. with S. lerda (Forsk.) C. V. and that they are identical. " Valenciennes confounds under the name of Chr. lerda, Bengal specimens of FAMILY, V— SPARID^. 141 Spams hasta ■with eleven dorsal spines and /Sjj. benla, Forsk." (Gunther, Catal. i, p. 491). Professor Peters having shown me a specimen 14| inches long with Bl. Schn.'s name Sparus hasta on it, marked as his type, and which was sent to Valenciennes, by whom it is also labelled, I certainly think that Valenciennes was correct and the specimen belongs to the variety calamara. Hahitut. — Red Sea, and seas of India to the Malay Archipelago and beyond. I have taken specimens of berda in Sind 30 inches in length. The calamara is known as " black rock cod" in the Madras Presidency, and is excellent eating : it is common in Malabar until July. 3. Clirysophrys Cuvieri, Plate XXXIV, fig. 3.

Length of head 2/7 to 1/4, of caudal 1/6, height of body from 2/7 to 1/3 in the young of the total length. Uijes — diameter 1/6 (to 1/4 in the young) of length of head, Ij to 2 diameters from end of snout, and 1| apart. Dorsal profile scarcely elevated in the adult, that of the abdomen almost horizontal. Preorbital low in the 3'oung with an almost straight inferior edge, in an adult (as 14| inches) the depth of the preoi'bital equals the diameter of the eye. The maxilla reaches to below the front third of the oi'bit or to under its centre in the adult. Vertical limb of preopercle very minutely serrated in the immature : opercle with a distinct spine. Teeth — four to six sharp, pointed and rather conical incisors in front of either jaw, with villiform teelh behind them : a pointed and compressed row along the outer side of either jaw, the last few of which ai'e small and with rounded crowns ; internal to these are two rounded rows of small molars in the lower and three in the upper jaw. In a fine specimen 14| inches in length this distribution of the teeth is still seen, and the size of the molars is far less than is apparent in any other of the genus taken in India ; they approach very close to the dentition of Bentex nufar, pi. 34, f. 4, which was mislaid until too late to insert in its proper place. Fins — alternate dorsal spines strongest on one side, the fourth or fifth being the highest, and nearly equalling the length of the postorbital portion of the head in the young or 1/3 the height of the body in the adult : pectoral not quite so long as the head : first anal spine short, the second strong and equal to half the length of the head or even more in the young, but it greatly decreases in comparative length with age, being only 2f in the length of the head in the adult : caudal slightly lobed. Scales — seven rows between the eye and angle of the preopercle : a few over the base of the soft portion of the dorsal : a band at the base of the anal : the caudal with fine ones almost to its end : four entire and two half rows between the lateral-line and the base of the spinous dorsal : 10 rows between the base of the ventral fin and the lateral-line. Lateral-line — very slightly curved. Colours — silvery-gi'ey, about eight Hnes radiate from the eye and posterior edge of the preorbital : each row of scales has a darkish band along its centre : dorsal and caudal fins black tipped, a grey band along the centre of the dorsal fin and a grey spot at the base of each spine and ray : anal spines grey, the membrane and rays black except the two last rays which are white. This species difiers from the C. datnia in its teeth and more pointed snout, whilst the head at its widest part only equals its postorbital length. It is identical with the two specimens of Dentex hasta, C. V. in the Paris Museum. Habitat. — Seas of India to at least 14i inches in length : the figui-e is from a specimen captured at Mangalore measuring 14J inches. 4. Chrysophrys bifasciata, Plate XXXIV, fig. 5.

Teeth — six large compressed incisors in the front of the upper and four in the lower jaw : five rows of rounded molars along the sides of the upper and four in the lower jaw. Fins — dorsal spines strong increasing in length to the fifth, which is two-fifths of the length of the head, whilst the rays are scarcely higher than the spines : pectoral a little longer than the head : ventral does not reach the anus : second anal spine much the strongest and equal in length to the third : caudal forked. Colours — silvery, with dark lines along each row of scales on the body, and having two black cross bands, the first through the eye, the second over the hind edge of the opercle : a yellow band before the eyes, snout black, dorsal, caudal and pectoral yellow, dorsal spine black, and a narrow black edge along soft dorsal : ventral and anal black except the last anal ray which is yellow.

Eyes — diameter 3|- to 4 J in the length of the head, I3 to 2 diameters from end of snout, and 1 apart. Dorsal profile more convex than that of the abdomen, a prominence over the forepart of the orbit causing the snout to appear somewhat vertical : posterior nostril very elongated. The maxilla reaches to below the first edge of the orbit. Preorbital deep, being 1 diameter of the orbit in height. Prcopercle entire : opercle with a spine. Teeth — six conical and compressed ones iu front of either jaw, sometimes only four in the lower, the remainder of the teeth with rounded crowns the largest being in the inner row, three rows in lower four in upper jaw. Fins — dorsal spines i-ather weak, their breadth on both sides being nearly equal, the fourth the highest and equal to two-fifths of the length of the head. Pectoral longer than the head : ventral reaches the anus, its spine a little longer than the fourth of the dorsal : anal spines comparatively weak, the second a little the strongest and slightly the longest, equal to 2j to 2f iu the length of the head : caudal lobed.

Interopercle with a blunt spine and tentacle. Opercle with a central bony ridge ending in two spines. Temporal ridge containing three spines, and occipital one likewise spiny ; whilst there is one spine between it and the ridge below it.

Tentacles — none apparent over the orbit (?) : very distinct on lower iaw and different parts of the head. Valenciennes observes that its most remarkable character is that all the skin of the head between the spines is as if it were veined with small scooped out lines which join on all sides and thus form a network which has the appearance of scales. Teeth — none on the palate. Fins — fourth dorsal spine the longest and equal in length to the second of the anal which is 2/5 of the length of the head. Scales none on head, those on body oblong, ctenoid with a single row of minute spines along its marginal liorder.

The fins irreg'ularly streaked black and red : the ventral at its root is pink like the belly."— (Russell.) M. Sauvage, who has kindly compared Valenciennes' type specimen for me with a drawing I made of )S'. rosea has furnished mo with the additional information detailed above. He likewise observes " 8. venosa differs from S. rosea (according to your figure) by the head being more elongated : the body also more elongated and the dorsal spines not being so high." Habitat — Coromandel coast of India. Genus, 5 — Pteeois, Cuv. . Macrochjrus, Pteroleptus, Pteropterus and Braehjrtis, Swainson. BraiicMostegals seven: pseudolranclrice. Head rather large, armed vdth spines and having sKnmj flaps -. no occipital groove. ViUiform teeth m jaws and on vomer, none on the palate. A single deeply notched dorsal fin, having from twelve to thirteen spines: anal with tivo or three spines and few rays: rays, and sometimes spines, elongated: no pectoral appendages. Air-vessel large. Pyloric appendages few. Geographical distribution. — Epd Sea, coasts of Africa, through the seas of India to the Malay Archipelago and Polynesia. It does not appear that any very great value can be placed on the comparative length of the dorsal spines, or pectoral rays in this Genus of Fishes, as they are subject to considerable modifications, some being dependant upon age, and others seem to be subject to variation in specimens of the same species. It has yet to be ascertained whether the orbital tentacle is equally developed in both sexes. SYNOPSIS OF SPECIES. 1. Pterois Bussellii, D. I2-| yxiTT' ^- ^- H- -^ short supraorbital tentacle.

Body strongly compressed : profile from dorsal fin to snout oblique : mouth slightly oblique, lower jaw a little the longer. Preorbital with two blunt spines, the longest going backwards to beneath the first third of the eye,_ the lower and shorter one a httle downwards and backwards. A rough ridge passes across the suborbitals to a little above the ano-le of the preopercle on the vertical limb of which are two blunt spines, the upper the longer, and equal to the diameter of the orbit in length : two more smaller spines along its horizontal limb : three opercular^ spines : an elevated occipital ridge, and also a temporal one having three blunt spines. No barbels, recf/i— villiform in iaws and vomer, none on the palate. Fins — dorsal fin continuous, it commences over the middle of the eye ; spines strong, the second being slightly the longest and equal to half the height of the body, they subsequently slio-htly decrease to the last which is as high as the first ray : a membraneous extension exists from the end of °the dorsal fin, and nearly reaches the base of the caudal. All the articulated fin-rays are unbranched. Pectoral equals the length of the head and reaches to the commencement of the anal : ventral short, reaching half way to the anus, it has one spine and three rays : two weak anal spines only : caudal rounded. Scales- absent, skin with many widely spread rough elevations, becoming somewhat spinate in large specimens : tubes of lateral-line 10 or 11 distinct ones in number, which occupy its whole length.

Dorsal fin edged with white, having a dull grey band along its centre, and most distinct in its last half : caudal edged with white, and having a dull base due to numerous grey spots : pectoral and anal reddish, the former having many black spots upon it : ventrals white. These fish are very common in Macb-as in October, and through the cold months, but they rarely exceed 2h or 3 inches in length. . Jerdon observes (Madr. Journ. Lit. and Sc. 1851, p. 141), " Agrioims , I possess a drawing of a small species of this genus of a mottled red colour throughout. I only procured it once, it was named Crasi toumhi, Tam." The specimen is in the British Museum, as Tetrarorje twjiiamtus (ii,p. 13G), from which it may be readily distinguished, as the spines on its head are blunt, and its articulated fin-rays are unbranched, which is not the case in A. tceniajwtus (see p. 157). My reasons for considering this distinct from C. echinatus are the more obhque profile from the snout to the dorsal fin : the second dorsal spine (instead of the first) being the highest : the pectoral having 14 (instead of 10) rays, &c. . Habitat.— Covom&ndcl coast of India. The specimen is figured life-size. Genus, 13 — Pelor, Cuv. and Val. Branchiostegals seven. Read irregularly shaped. Villi form teeth in the jaws and vomer. The three first dorsal spines conne'ded hy a membrane and are at a little distance pwn the others (12-14) which are som&ivhat isolated one from another, due to the interspinous membrane being deeply cleft : two free rays at the base of the pectoral fin, having a connecting membrane: ventrals tlioracic.

The shoulder spot becomes dark, but the spot on the upper edge of the eye remains. The black shoidder spot has been omitted in Bl. Schneider's figure, which otherwise is not incorrect : when freshly captured the bars across the caudal fin are very distinct.

It must however be added that Schneider's specimen m spirit is still in good preservation at Berlin. Mahitat.— Common along the coasts of India, attaining at least nine inches in length.

Eyes — diameter 2| to 2| in the length of the head, 1/2 a diameter from end of snout, and 3/4 apart or nearly 1/4 in the length of the head. Head slightly longer than high. Chin prominent : the maxilla, which is not denticulated, reaches to below the last third of the orbit. Under surface of lower jaw rouglily and irregularly farrowed : pre- and sub-orbitals serrated, also both limbs of the preopercle : a moderately strong opercular spine with two or three above and below it ; the lower half of the opercle, the sub- and the inter-opercles serrated. Teeth — villiform. Fins — dorsal spines weak, the longest being half the length of the head : second dorsal higher than the first : pectoral equals the length of the head behind the front third of the orbit : the ventral reaches two-thirds of the way to the anal : fourth anal spine the longest and equalling the diameter of the orbit but not so strong as the thii'd : caudal forked. Scales — seven to eight rows anterior to the dorsal fin : seven along the preopercle : two entire and two half rows between the lateral-line and the base of the dorsal fin. Free portion of the tail rather higher than long. Coloiirs — scarlet, the edges of the scales violet, more especially above the lateral-line : longitudinal bands, alternately lighter and darker along each row of scales.

I have only collected two species of this genus on the Coromandel coast of India (see pi. xli.), and am of opinion that they are the two that Russell (plates civ. and cv.) obtained from the same place. Russell distinctly shows one has a band on its eye, pi. civ. (see also pi. sli. f. 2.) The one with the banded eye is by far the commonest, and I consider it as M. munljun. The second species is easily recognised by its more or less black fins, and appears to be M. adustiis. Admitting that Russell's description does not coincide, neither does it with his own figure. He gives B. viii, D. ii (fi-), P. 15, V. 1/7 il), A. A (y%), C. 21 ; his figure gives D. ^l, A. ^, demonstrating that his numbers are not tnistworthy. Jerdon (M.'j. L. and Sc. 1851, p. 131) observes: " MyrqjrtsHs hutcJte,C.Y. Moowla Jcun Icakasi, Turn. Russell, 105." Dr. Giinther, Catal. i, p. 21, considers Russell's fish (pi. cv.) is identical with M. murdjan, but Blocker [joints out that the colours in the two are very difTerently disposed on the fins.

Posterior edge of hind nostril usually serrated in the young. Lower jaw slightly the longer, having a rough, nipple-like projection on either side of the symphysis. The maxilla reaches to beneath the last third of the orbit, it has some blunt denticulations on its front near its lower end. Under surface of lower jaw fm-rowed by ten or twelve grooves : the maxilla, pre- sub- and Lnter-opercles also gi'ooved. Preopercle serrated in its whole extent. Interopcrcle finely denticulated : opercle with a moderately strong spine, having a few denticulations above it, and the whole of its outer margin below it serrated. Sub-ojjcrcle with an emargination opposite the base of the pectoral fin. Shoulder-scale s'errated. Upper surface of the head roughened by three or four raised lines, which, passing backwards, divide and subdivide, each terminating in a small spine. Teetli — villiform in the jaws, with an external row of widely separated ones which are larger and conically rounded, none on the tongue. Fins — dorsal spines increasing m length to the third which i.s about the same height as the three next or ecpial to one diameter of the orbit, the interspinous membrane rather deeply emarginate, front portion of the second dorsal higher than the first.

A dark vertical band tkrough the eye, sometimes confined to above the pupil. Dorsal, caudal, and anal fins with milk-white outer edges ; a dark mark, often deep black, may be present or absent at the highest points of the soft dorsal and anal fins, also at the tips of the caudal. Rarely there is a dark mark along the first dorsal. Outer edge of ventral white. Myripristis Jcmdee, Cuv. and Val. vii, p. 487, was considered in the Hist.

A small FAMILY, IX— BERTCID^. 171 BmncMostegals eight. Eyes large, lateral. Jaws of equal length, or the lower sUghthj the^ longer: snout of moderate length. Operdes and suborbitals serrated: opercle with two sjnnes : generally a large spine at the angle of the preoperde. Vilhform teeth on the jaws, vomer, and palatines. Two dorsal fins scarcely united : ventral wdh^ one spine and seven rays: anal with four spines, the third being long and strong : caudal forked. Scales ctenoid, oj moderate size. Air-vessel oval and simple. Pyloric appendages numerous. Bleeker observes that amongst the characters by which these fishes may be distinguished_ one from another, especial notice should be taken of the number of rows of scales on the preoperde, the relative height of the two last dorsal spines, and the presence or absence of spines at the margin of the nostrils or the end^ot the snout. To show that these intra-nasal spines are not invariable I would refer to H. Andamanense, p. 1/2. It appears that in some at least of the species of Holocentrmn, the comparative length of the preopercular spine to that of the body increases vdih. age, whereas, as already observed (p. 9) in Serrani or Lidiani (p. 29), when one exists at this spot in the immature it becomes more or less absorbed in the adult.

The maxilla reaches to below the centre of the orbit. The posterior process of the premaxillary shorter than the diameter of the eye. Upper surface of the head roughened with sinuous lines which posteriori}' end in spinate points. Suborbital ring of bones narrow, fluted and serrated in their whole extent. Preopercle likewise fluted along its vertical Hmb, liavinc a strong spine as long as the orbit at its angle and serrated along both limbs. Opercle evenly fluted, armed with two spines (the lower being the shorter) and its outer edge strongly serrated : sub- and inter- opercles fluted and denticulated : shoulder-bones denticulated. Snout with two sharp nipple-shaped spines on the prcorbital and intermediate serrations : no spines at nostrils. Teeth — villiform. Fins — dor.sal spines strong, the third to the fifth the longest, the third equallmg half the height of tlie body, but not so high as the soil portion of the fin. Pectoral reaches to the twelfth scale of the lateral-line, and the ventral three-fourths of the way to the anus. Third anal spine very strong, its height equalling about 2/3 of the height of the body, whilst it is 2/9 to 1/5 longer than the fourth spine. Caudal forked. Scales — six or seven rows between the occiput and the base of the first dorsal fin: seven rows along the preopercle. Colours — in the young silvery white with longitudinal dull rosy bands from the opercles, the second and third coalescing. In the adult it is red vntli seven or eight silvery bands. Head more or less rosy as are also the fins. Occasionally there is a little dark about the latter. In the Fishes of Zanzibar, " Var. b, has a large black blotch at the base of the soft dorsal and anal, a third at the root of the caudal, and a fourth at the axil of the pectoral. This is clearly identical with that described by Bleeker as H. melanospilos. These varieties are structurally identical, and the difference in coloration is probably a sexual one ; one specimen of Var. b proved to be a male fish, at or near spawning time." (P- ■->-)■ Respecting colour, the one I have figured, destitute of any black, was a male. Jerdon's specunen (sem- pooravi, Tam.) has a black spot at the base of both soft dorsal and anal fins, and a third above the superior opercular spine, whilst the margin of the preopercle is dark-edged ; it has no vestige of a spine inside the nostril, as exists in Holocentrum melanospilus, Bleeker.
