F. DE BEAUFORT LEIDEN — 1916. E. J. BRILL Ltd. V.3 uO PRINTED BY E. J. BRILL, LEIDEN (HOLLAND). INTRODUCTION. In continuation of the preceding volume of this series, in which, besides other groups, were treated the Siluroidea, as first suborder of the Order Ostariophysi, the present or third volume of the "Indo-australian fishes" contains the remai- ning suborder of the Ostariophysi'. the Cyprinoidea and the Order Apodes, to which is added the Order Synbranchi. We refer to the introduction of that preceding volume for the geographical limits of the faunistical region, wherefrom the fishes are here described. In the quoted introduction we have also made some remarks about the material in general at our disposal. The following may be added for the present volume. A great part of it, as far as it contains the descriptions of the Cyprinoidea, is devoted to fishes living in the fresh water of streams, brooks, ponds and lakes from the western part of the Indo-australian Archipelago, especially from Sumatra, Borneo, Java and neighbouring Islands, reaching eastwards not farther than Borneo and Sumbawa. The Synbranchi and some of the Apodes have a wider distribution in the fresh water of the Archipelago. The remaining Apodes are inhabitants of the coral reefs, of the sandy and muddy literal region, of the brackish water of aestuaries, of the bottom of deeper water, a few even of the true deep sea. Many live below stones, below blocks of coral or find shelter in crevices of rocks or coral reefs, some burrow in sand or mud, while others are met with in surface water. For the study of the fishes treated in this volume we could dispose of the various collections named in the introduction to the second volume of this series. Since then we received valuable material from Dr. L. PH. DE BUSSY from Deli, from Mr. EDWARD JACOBSON from West-Sumatra (Padangsche Boven- and Beneden-Landen), from Mr. P. BUITENDIJK from the Java Sea, from Mr. G. HERMAN from Sabang, Pulu Weh. VI We are glad of the opportunity to thank Dr. J. C. KONINGS- BERGER, Director of s Lands Plantentuin at Buitenzorg, Java, for the great advantage of his collaboration and interest in our work. He allowed us to study all the Cyprinoidea, Apodes and Synbranchi belonging to the Zoological Museum at Buitenzorg and to the " Visscherijstation" at Batavia. Our thanks are therefore also due to Major P. A.OUWENS, keeper of that Museum and to Dr. A. L. J. SUNIER, head of the Station for Fishery Investigation at Batavia, who was kind enough to forward the collection to us and gave us valuable information about its content. Greatfully we acknowledge the great help we had, in prepa- ring this volume, from the ichthyological material of the Rijks Museum at Leiden. Through the kindness of its Director Dr. E. D. VAN OORT its riches were always at our disposal and by the untiring help of Miss Dr. C. POPTA, we could make use of the types described by herself, by VAILLANT and of some of the types and cotypes of BLEEKER and KAUP. The bulk of BLEEKER's types of Cyprinoidea and Apodes is contained in the British Museum (Natural History). One of us had the opportunity to study them: an opportunity without which our work had been insufficient and incomplete. We are therefore glad to thank the Director of the Zoological Depart- ment of that Museum, Dr. SYDNEY HARMER and especially Mr. C. TATE REGAN, under whose able superintendance the fish collection is placed, for the valuable and liberal help we always received. Dr. G. DUNCKER from the Hamburg Museum was kind enough to send us for inspection all the Cyprinoidea from the Archipelago, which are under his charge. This important col- lection was of much help in our study. We have also to thank Dr. J. PELLEGRIN for very valuable informations about some types preserved in the Museum d'histoire naturelle at Paris and Dr. R. GESTRO, Director of the Museo Civico of Geneva, for some cotypes of species described by PERUGIA. For the benefit of those who make use of this volume we repeat the technical informations, given in the introduction to the second volume of this series. In describing the fishes we understand by Length, in the VII discussions of the proportions, the distance between the snout and the base of the caudal fin; in giving the largest size known for a species, we include the caudal fin. The Head is measured from the tip of the snout to the end of the opercle, its proportion to the length is indicated e.g. as follows: head 4 — 41/2 means, that the length of the head is contained 4 to 41/2 times in the length. Height is the maximum height; in special cases it is indi- cated how it is measured; the figures placed behind "height" indicate how many times it is contained in the length. The size of the Eye, the length of the Snout, of the Jaws etc. are compared with the length of the head; thus "eye 4" means, that its diameter is J/4 of the length of the head. In counting the Scales, under "Z. /." is given the number of scales, with or without sensory organs, between the head and the caudal fin or, in most cases, between that fin and the upper corner of the opercle. ol/ L. t. ^ry^r signifies, that there are 3J/2 rows of scales between the dorsal fin and the lateral line and 6 to 7 below it, the lateral line itself is in this case not counted. In other cases 4V, the lateral line itself is also counted f. i. L. t. I (between I D. and V.), which signifies, that there are 4l/2 rows of scales between the dorsal fin and the lateral line, one in the lateral line itself and one between it and the ventral fin. In the Fin formulae the spines and the simple, non-branched rays are generally indicated by a figure, separated by a point from that of the number of the branched rays. The last soft ray of the dorsal and anal, in case it is cleft to the base and therefore counted as two by some authors (BLEEKER e. g.), is reckoned as one, being supported by a single pterygophore. The Gillmembranes may be totally free from each other and from the isthmus; they may be united, but still remain free from the isthmus; or they may be connected with the isthmus and with each other. When in the last case the posterior border of the united gillmembranes is not quite adnate to the isthmus, there remains a free posterior margin, running as a fold over the isthmus from one gillopening to the other. VIII The complicated structure of the parts of the mouth of many Cyprinoidea has found ample discussion, illustrated by figures, in the text. In describing the Apodes their dentition is of great impor- tance. To facilitate its description we have added in many cases a figure of the dentition as it is seen on an impression of the teeth in a bit of plasticine. For this purpose we introduce a thin piece of this material in the opened mouth of the fish, close it and extricate afterwards the piece with some caution from the reopened mouth. In this way often teeth are indi- cated, which otherwise are difficult to detect. We follow the law of priority and use the oldest name which can with certainty be made out by the description, belonging to a certain species. Its author is cited as the author of the species and his paper is quoted in the first place. Mention is further made of all synonyms; besides, we have quoted those papers, which contain a description of the species. If it is a widely spread one, only those papers are quoted, which contain a description of or give some informations - others than those regarding locality only — about Indo- Australian specimens of that species. According to the international rules of nomenclature we have neglected the generic names, as e.g. those of Swainson, which are not accompanied by a description. We have recorded under: "iiomina indigena" those native names, which seemed to us to be trustworthy. We are of opinion that no great value ought to be attached to them, as the unavoidable series of difficulties is still enlarged by the fact, that the authorities for those names have mostly been European ichthyologists and no linguists. There remains for us the pleasing duty of expressing our thanks to Mr. C. PELTENBURG, head of the firm E. J. BRILL Ltd of Leiden for the interest he took in publishing also this volume and to Mr. J. F. OBBES, the able artist to whom we are indebted for the faithful figures, which illustrate this volume. MAX WEBER. L. F. DE BEAUFORT. Eerbeek, Holland, July 1916.

Scaly, with exception i) Through the kindness of Dr. R. GESTRO, Director of the Museo Civico di Geneva, we had the opportunity to study 2 specimens of Helgia modesta Vinciguerra from Burma. They are closely allied to Homaloptera wassinki Blkr. but distinguished at once from this species by the lower number of pectoral rays which is 6.8 and by the slightly emarginate caudal. Miss C. POPTA, Ph. D. has called a specimen from river Mahakam, Borneo, Helgia modesta. It seems us more probable, that it belongs to Homaloptera wassinki Blkr. She gives the number 5.11 for the pectoral rays (one of us has counted 6.11), and gives besides other small differences from Helgia modesta. 10 of the abdomen, which is naked anteriorly from a point somewhat in advance of ventrals.

Origin of anal oppo- site to 3ist perforated scale of lateral line. Origin of ventrals opposite to i ^th perforated scale of lateral line. Pectorals slightly longer than head, reaching ventrals. Caudal equal to head, slightly emarginate, not deeply forked. Scaly, naked only be- tween the pectorals (according to Cuvier & Valenciennes: ,,la peau du dessous de la gorge et du ventre est nue et sans ecailles"). Eighteen scales round the caudal peduncle. Colour of the alcohol specimen rufous, with 5 black round blotches on the back of the tail. Length of single known specimen 73 mm. Habitat: Java (Buitenzorg). Note: As the description of CUVIER & VALENCIENNES was so insufficient that we at first thought that it was identical with Homaloptera erythrorina (C.V.), we asked Dr. J. PELLEGRIN to inform us about the type in the Paris Museum. He was so kind to give us ample information about the principal characters of the specimen of CUVIER & VALENCIENNES, which enabled us to give the above description. It shows that it is nearest to H. wassinki, but differs from it by minor height, larger eyes, by the position of the dorsal and by the caudal which is only slightly emarginate. II In the single specimen described by Miss POPTA Ph. Dr. (see note pn page 9) from Borneo, we find the height and the caudal as in H. wassinki, but the eye and the position of the dorsal is as in H. ocellata. As also H. ocellata is founded on a single specimen, we think it possible, that H. ocellata and H. wassinki belong to one and the same species. 3. Homaloptera modiglianii Perugia.

Note. We have included N. saravacensis in the synonymy of N. fasciatus as the differences, given by BOULENGER, do not hold good. The difference in the number of the dorsal rays is not noteworthy. We find in specimens of N. fasciatus (from Java) the origin of the dorsal above the origin of the ventrals or slightly before them, but never behind. After inspection of the young specimens in the Leiden Museum, which VAILLANT calls Nemachilus rupicola Me Clell. whitout giving any reason for this definition, we believe that they belong to Nemachilus fasciatus C. V. Dr. GESTRO, Director of the wMuseo Civico" of Geneva has been kind enough to send us two typical specimens of Modi- gliania papillosa Perugia. We are obliged to unite it with Nemachilus fasciatus, as we cannot see the "papilla grossa conica, lunga meta il diametro dell' occhio alia regione prae- orbitale" and otherwise there is no difference from Nemachilus fasciatus. 3. Nemachilus olivaceus Blgr. Nemachilus olivaceus Boulenger, Ann. Mag. Nat. Hist. (6) XIII. 1894, p. 250. D. 3.8; A. 2.5; P. 10; V. 1.6. Height 5.6, 7 in length with caudal. Head 4.5, 5.6 in length with caudal. Eye 5, twice in length of snout, about I '/5 in interorbital space. Inner rostral pair of barbels shorter than the outer ones, extending to middle of operculum. Origin of dorsal originating above the base of the ventrals, and slightly nearer the end of the snout than the base of the caudal. Height of dorsal somewhat less than length of head. Anal halfway 42 between dorsal and caudal, originating midway between origin of ventrals and caudal or a little nearer to ventral; its height scarcely less than that of dorsal. Ventrals reaching anus, shorter than head and scarcely shorter than pectorals. Caudal feebly notched. Body entirely covered with imbricate scales, of which there are about 30 between dorsal and ventral fins. Olive above, with or without traces of 17 darker bars across the back, yellowish beneath; fins gray or grayish, without spots. Total length 85 mm. Habitat: Borneo (Bongon !). Note: This species, the types of which have been studied by us in the British Museum is hardly different from N. fas- ciatus (C. V.). The only differences are, that the caudal fin is feebly notched in N. olivaceus, deeply emarginate in N.fasciatus, that in the former the ventrals reach the anus, which is not the case in N. fasciatus. The latter species has also a series of black spots on the dorsal rays, which are wanting in N. olivaceus. Doubtful species. i. Nemachilus notostigma Blkr. Nemachilus notostigma Bleeker, Versl. Akad.

Body with twelve or thirteen brownish crossbands, broader than the interspaces between them ; base of caudal with a blackish transverse streak. Dorsal with a blackish spot at its anterior base, the rays with two to four black dots, as also the caudal rays. Length, as far as published 71 mm. 43 Habitat: Sumatra (Benkulen, according to E. VON MARTENS). - - Ceylon. We have placed this species under the doubtful ones, as we doubt, that E. VON MARTENS (Preuss. Expedition nach Ost-Asien, Zoolog. Theil, I. 1876, p. 404) was right in his determination of the species (of which he gives no description) of Nemachilus, caught by him in Benkulen, Sumatra, a species only known from Ceylon. Note: BLEEKER described (Nat. Tijdschr. Ned. Ind. II. 1851, p. 435) a Cobitis barbatuloides. In his diagnosis he says: "spinis suborbitalibus utroque latere 2, sub oculi margine anter- iore vel vix ante oculum sitis, spina posteriore anteriore majore; cirris 6 ? brevibus . . . ." Later on in a review of the Cobitinae (Nat. Tijdschr. Ned. Ind. XVI. 1858 — 59, p. 302) he gives the following diagnosis of his genus Cobitichthys-. "Oculi velati. Cirri 6 ad 10, rostrales 2, supramaxillares 4. Caput alepi- dotum. Spina suborbitalis nulla. Nares anteriores tubulatae. Pinna dorsalis ventralibus opposita. Vesica natatoria parva tota in cavitate ossea vertebrali inclusa. Corpus valde com- pressum. Spec, archip. Cobitis barbatuloides Blkr." This chang- ement of his opinion about the suborbital spine is explained in: Ichth. Arch. Prodom. II Cyprini, 1860, p. 82. In his Atl. ichth. III. 1863, p. 14 the species in question is called Mis- gurnus barbatuloides Blkr. As also the number of barbels is uncertain and BLEEKER himself says : "1'espece merite d'etre examine de nouveau," we only draw attention to it, but dare not to give a description. 3. Fam.

Scales small, moderate or large, lateral line running along the median line of the tail (exc. Leptobarbus). Pharyngeal teeth generally in a triple series, exceptionally in a double or single series. 92 The formation of the parts of the mouth of this family is very diversified but allows to distinguish three types. In the most simple one the mouth is anterior or subinferior and more or less protractile ; the lips are thin, thick, crenulated or papillated. (By lip we understand a more or less developed fold of the skin, which is more or less distinctly separated from the covering of the jaws). The upper lip is uncovered or only partly covered by a fold containing the maxillaries, forming a simple not pendulous continuation of the skin of the snout directed forwards (fig. 33). In a second type the mouth is conspicuously inferior, bor- dered by thick, continuous lips, which may be fringed or papillated. The upper ones are partly covered or bordered by a pendulous rostral fold of the skin of the ventral surface of the rostrum, (fig. 34 and 35). In the third type there is no rostral fold; the skin of the ventral surface of the rostrum is continued into the upperlip, which is fringed or papillated. Mouth inferior but otherwise very complicated and very differently constructed (fig. 36 and 37). In many Cyprininae the lower lip is separated from the skin of the isthmus by a complete postlabial groove, which is conti- nued round the corner of the mouth. This groove may be interrupted in the middle, so that there are separate grooves, one behind each lateral part of the lower lip. (fig. 38, cfr. also Dangila and Osteochilus).

Leptobarbus melanopterus n. sp. Differs from the preceding species, when compared with specimens of equal size, by having a much greater breadth of its body, which may account for its having 5 !/2 scales above the lateral line in the linea transversalis, and 15 scales round the caudal peduncle, 8 of which are above the lateral lines. The third spine of the dorsal is longer than the head. Upper and lower half of caudal with a broad black intramarginal longitudinal band. A similar one on anal. Ventrals, pectorals and dorsal nearly totally black. Length of single specimen 242 mm. [Type of the species in the zoological Museum of Amsterdam]. Habitat: Borneo (Upper Kapuas: Selimbau!); collected by Mr. H. A. LORENTZ. Note: We presume that BLEEKER had this species too, as he says from L. hoeveni: "Un de mes plus petits individus montre une bande noiratre longitudinale a chaque lobe de la caudale, mais je n'en vois rien dans tous les autres." 3.

We made this description after two specimens from the Island Singkep and after one specimen from Samarinda, Borneo. We are not sure that this is the Barbus armatus of C.V. and of BLEEKER, as our specimens are higher. The differences in the number of scales of the 1.1 is of no importance, as we would find a higher number when counting the two small scales perfo- rated by the 1.1, which runs upwards along the hindborder of the operculum. Moreover BLEEKER gives for the 1.1 35 in his des- cription of B. valenciennesi, which he himself afterwards con- sidered to be the same as B. armatus. Principally on account of the high and short caudal peduncle of our specimens, through which characteristic they differ from B. repasson, we bring them to B. armatus. Moreover there is a difference in the relative length of eye and postorbital part of head. We find only 2 barbels in the two specimens from Singkep, but we do not i65 think this of great importance, as GuNTHER (1. c.) says that one of the typical specimens of BLEEKER had also only 2 barbels. 10.

Anal inserted about midway between origin of dorsal and base of caudal, third ray enlarged but with flexible tip, and depressed fin reaching opposite base of caudal. Caudal damaged. Pectoral low, small, and reaching back for about first fifth of length of ventral. Ventral with first branched ray longest and reaching anal.

Lower surface of head pale like abdomen. Fins same color, dorsal more or less tinted with dusky, and caudal and anal with brownish. Iris pale brassy- brown". Length 85 mm. [After FOWLER, not seen by us]. Habitat: Borneo (Baram river). We think it probable that this species is only a young specimen of C. siaja. When FOWLER writes: "it agrees with BLEEKER's description of Capoeta enoplos, but his figure (Atlas Ichth. III. 1863, p. 82, PL (27) 128 fig. 2), agrees with Sumatran examples of Cyclocheilichthys siaja, which may be distinguished by the smaller eye, always less than a third of the length of the head", he overlooked that the quoted figure refers to Barbus enoplos Bleeker, which is a quite different species. 17.

Note. BLEEKER has founded his Puntius (Barbodes] koilo- metopon on two specimens of 153 and 164 mm. which, according to him, differ from Puntius javanicus in having a more slender operculum, the length of which is contained twice in its height, whereas it is contained i2/3 — 13/4 times m javanicus. Moreover the body is higher (height about 3 in length with caudal) and the dorsal profile very much concave at nape. GtJNTHER (Cat. Brit. Mus. VII. 1868, p. 119), who had the two typical specimens at his disposition, says: "I do not think that B.koi- lometopon is specifically different from B. javanicus. The specimen figured by BLEEKER has the body conspicuously elevated, the pectoral extending beyond the base of the ventrals; but this is much less the case in the second specimen, so that it is even doubtful whether this form can be considered a con- stantly distinct variety." After reexamination of the two above named specimens, we agree with GtJNTHER that they do not differ specifically from P. javanicus Blkr. The difference in the operculum, named by BLEEKER, does not exist. The height of one of the specimens is nearly 2.2 and of the other 2.3, whereas we find the height of P. javanicus as 2.4 — 2.6. 199 25.

Now B. proctozysron Blkr. is very easy to recognise by its strongly dentated anal spine, a character unique among Barbini^ as BLEEKER has shown. We suppose, that the definition of v. MARTENS, which he doubted himself, was erroneous. B, proctozysron is therefore till now only known from Siam. 202 Nom. in dig. : Kepiat (Djambi); Tjipo (Palembang).

If this is really a distinct species, it differs, according to BLEEKER and GUNTHER, from T.falcifer by having the height of the body equal to the length of the head. According to BLEEKER the height of the head goes i2/5 — 13/7 in its length in T. schwanefeldi, and i!/4 to scarcely more than once in T. falcifer. Moreover T. schwanefeldi is said to have a light yellowich narrow lateral band running above the lateral line.

[After KNER, not seen by us]. This species was placed by KNER with a query in the genus Pachystomus. GliNTHER mentions it as a Bar bus and says: ^said to be from Java, but evidently allied to the east- asiatic types of Barbus" KNER himself gives as habitat: wvon Java?" It is therefore very doubtful if this is really a Javanese species, as the localities given by KNER are often erroneous. Ellopostoma Vaillant. (VAILLANT, Notes Leyden Mus. XXIV. 1902, p. 145, note).

Pectorals somewhat longer than head, not reaching ventrals. Caudal much longer than head. Least height of caudal peduncle somewhat less than its own length and more than twice in head, surrounded by 24 scales. Silvery, with about 2 irregular series of dark patches of different size and form on the upper half of the body. Length 5 1 mm. [Type of the species in the Leiden Museum seen by us]. Habitat: Borneo (river Kapuas!). Note: VAILLANT places this species in the enigmatic genus Aperioptus Rich, (see p. 238). We think there is no reason to do so. We therefore use for it the name Ellopostoma, which VAILLANT proposed in case his fish should appear not to be an Aperioptus. In the second place VAILLANT brings Aperioptus and there- fore also Ellopostoma in the family Cobitidae. We doubt the correctness of this view, although we are not able to say, to which family of Cyprinidae these probably young fish belong. Cirrhina breviceps C.V. Cirrhina breviceps Cuvier & Valenciennes, Hist. Nat. Poissons XVI. 1842^.293. VALENCIENNES mentions this species from "la riviere de Bantam." Already BLEEKER (Ichth. Arch. Ind. Prodr. II. Cyprini 1860, p. 140 and Atl. Ichth. III. 1863, p. 54) has doubted the cor- rectness of the definition of VALENCIENNES. The description was made after a dried specimen, which VALENCIENNES saw in the Leiden Museum but which does not exist there any more. Probably it was a species of Labeo.

KAROLI (Termeszetrajzi Fiizetek V. 1882, p. 43) mentions in his list of collected fishes Opsariichthys temmincki (Schleg.). from Borneo, Sarawak. We suppose that this habitat is erro- neous as the quoted species is only known from Japan. APPENDIX. Aperioptus pictorius Richardson. Aperioptus pictorius Richardson, Voy.

(After RICHARDSON). „ before I had examined them, except very cursorily. While ,,he was employed in sketching, he put them into a plateful wof water for the purpose of expanding their fins more per- 239 ,,fectly, and forgetting that he had not returned them into the ,,spirits, they were thrown out and lost. The general aspect ,,of the fish is that of a slender Galaxias, but there are no ,,teeth on the jaws. The orifice of the mouth is a narrow „ vertical oval, which is restricted on the sides by membranous ,,processes. The figure is of the natural size. ^Habitat: Borneo." We reproduce his figure. GUNTHER (Cat. Brit. Mus. VII. 1868, p. 371) says about this species: "Unfortunately the specimens were lost, so that no description could be given of them. The fish has the form of a Lepidocephalus, the dorsal being placed far backwards, nearly opposite to the ventrals. But the mouth is represented as transverse, curiously lobed, and without barbels." Its position is doubtful. Certainly it has nothing to do with Aperioptus megalomycter Vaillant described by us as Ellopostoma megalomycter (Vaillant) on pag. 237. Order APODES Linne. Physostome.

According to BLEEKER it is distinguished from C. anago (Schlegel) by the jaws, which are of equal length, and having the vomerine teeth only in 2 rows and having a diffuse silvery longitudinal lateral band. G0NTHER says I.e. p. 43: "Conger neoguinaicus Bleeker (Act. Soc. Sc. Indo-Neerl. VI. Nieuw Guinea, p. 22), or Ophisoma neoguinaicum Blkr. (Atl. Ichth. Mur. p. 28), is founded on an example so badly preserved that 264 no really distinctive characters can be pointed out. It is possible that it is identical with C. habenata" But OGILBY rightly remarked I.e. p. 286: "Dr. GtJNTHER's suggestion that this species ""may be identical with C. Jiabenata"" cannot be ac- cepted if BLEEKER is correct in describing the jaws as of equal length, the snout as 4x/2 in the length of the head, and the vomerine teeth as biserial and " "bluntly conical""; indeed, in view of the latter character, I am not fully satisfied that the species properly belongs to the present group." 4.

Teeth pointed, recurved, uniserial. Gill- openings small, ventral, vertical, transversally connected by a furrow. Distribution of the single specimen known: Indo-austra- lian Archipelago. Note: This genus differs from Sphagebranchus by the posterior nostrils, situated above the upper lip, below and behind the eye; it is by this arrangement that this genus is distinguished in the family of the Ophichthyidae, as there is only in Ophi- surus serpens (L.) a comparable arrangement. In this species the anterior nostrils are situated in the middle between eye and tip of snout, at some distance above the upper lip; the posterior nostrils are oblique slits before the vertical through the frontborder of the eye, slightly above the border of the upper lip. i.

Snout pointed, its conical part projecting beyond the lower jaw by more than one eyediameter. Cleft of mouth thrice in length of head, reaching far behind eye. Origin of dorsal somewhat behind that of anal. Dorsal and especially anal very low. Gillopenings longer than eye, situated ventrally, and trans- versally connected by a furrow. Head and neighbouring parts of back with light and dark marmorations, otherwise back with dark points continued downward as dark patches between the light round blotches along the lateral line. Length of single specimen known 167 mm. [Type of the species in the Zoological Museum of Amsterdam]. Habitat: Flores : Strait Molo, sandy bottom, 69—9 1 M. depth!. i) This is at least our interpretation of the rather long slit. We are not able to make out in the single small specimen at our disposition, that this slit is really in communication with the nasal cavity, but as there is no other posterior nostril, we take this slit for the posterior nostril. 283 2.

XXIII (1903) 1905, part II. p. 586), BRAUER (1. s. c.) and LLOYD (1. s. c.) suppose, that this species is identical with Serrivomer beani Gill & Ryder, (Proc. U.S. Nat. Mus. VI. (1883) 1884, p. 260). But 6". beani has only 138 rays in the anal and its height is only 29.7 in the length according to GlLL & RYDER. If this difference from S. sector is constant, we are of opinion that both species are valid. Otherwise the name beani has preference as being the older. 333 4. Avocettina Jordan 8: Davis.

On vomer in young specimens one short series, which later on gets irregu- larly and incompletely biserial; in old specimens 2 short series. Mandibulary teeth in young biserial ; the outer series of small teeth disappears with age and remains only anteriorly. Colour 365 changing strongly with age. The original colour is yellow, ornamented with round, blackish spots, about of the size of the eye, arranged in three irregular, longitudinal series. These spots get a yellow centre (polyophthalmus see fig. 182). Later on they are increasing in size as also their light centre, whilst their periphery gets irregular; still later on they are broken up and the fish is finally brownish gray above, whitish below, covered by an infinite number of very small black spots, whilst the abdomen is generally whitish or covered with a few round or irregular spots.

On vomer a single or an incom- pletely biserial series. In each mandible a series of about 20 to 30 compressed, subequal teeth, inside of them anteriorly about 6 canines. These teeth as also the inner maxillary ones and those on intermaxillary plate are depressible. The colo- ration shows many varieties of which the following have been observed in our region. a. Brown with numerous white or yellow spots; gillopenings may be black (meleagris, chlorostigmd], b. Brown with numerous more or less distinct and more or less distant small or irregularly ovate or transverse black spots (buroensis, griseo-badius BLKR., duivenbodi), sometimes almost uniformly brown. Outside our region the most distinct varieties are: 369 c. Brown with black and white spots, irregularly distributed or arranged in longitudinal series (laysanus). d. On a whitish groundcolour the brown is arranged in a some- what regular network, giving the appearance of indistinct whitish spots surrounded by polygonal brownish interspaces, which are most distinct on the tail (ercodes). Length approaching 1000 mm. [Specimens of G. buroensis, griseobadius and chlorostigma of BLEEKER'S collection seen by us].

VIII, p. 117) united this species with M. nubila Rich., but afterwards (Siidseefische, I.e.) he separated it again, as no transitions between the typical colo- ration of the head of M. chilospilus and that of M. nubila could be found. He remarks, that all specimens known are of com- parative small size and that therefore it may be the young stage of an other species. In our material however we have a specimen from Kei-Islands of 240 mm. in which the ovaria contain well developed, although not quite ripe eggs. This species is closely related to M. zonipectis (Scale), which has however an other pattern of the spots on the head, and to M. richardsoni. From lastnamed species it may be distinguished by its more pointed snout, its longer tail, smaller gillopenings and by having generally only one row of teeth on the vomer. 15.

GONTHER (Fische der Siidsee, Heft IX. 1910, p. 413) united it with M. undulata. It may be possible that it is a young stage of this species, but as no transitional stages are known, as far as we are aware, we think it better to keep it as a distinct species for the present. 17.

Note: JORDAN &SEALE (l.s.c.) have united Muraena canina of QUOY & GAIMARD (1. s. c.) with Enchelynassa Bleekeri Kaup. Notwithstanding the description of QUOY & GAIMARD is insuf- ficient, we follow JORDAN & SEALE in their interpretation, because the french authors say about the nostrils: "narines tubulees". It is clear that they mean by "narines" the poste- rior nostrils, for from their descriptions of other species of Muraena it appears, that they knew the tubes of the anterior nostrils, but did not recnognise them as such. They use the name "narines" only for the posterior nostrils. Moreover their description of the dentition, of the head as "capite crasso", of the colour as "uniformement noiratre" makes it plausible, that the opinion of JORDAN & SEALE is right. 5.

KNER (Novara-Exp. Fische, p. 387) gives a descrip- tion of a fish from Tahiti, which he calls Gymnomuraena tigrina, but which can not be the present species, as KNER states that head and trunk are about equal to tail. DAY'S G. tigrina (Fishes of India 4°. 1878 — 1888, p. 674) must also be an other species, as he says: "Tail nearly twice as long as body". This may however be a misprint. It may be noted here that BLEEKER makes a similar mistake in his Atlas Ichthyologique, where G. tigrina is characterized in the key by: "Queue beaucoup plus longue que le tronc". In the "remarques" following on i) BLEEKER has shown (Versl. Akad. Amsterdam XV. 1863, p. 462) that KAUP has confounded Gymnomuraena marmorata and Gymnothorax polyuranodon under this name. 395 the diagnosis he also says that this species is characterized by : "la queue, qui est beaucoup plus longue que le tronc". In his diagnosis however it is clear that the reverse is meant. 2. Gymnomuraena concolor (Riipp.). Uropterygius concolor Riippell, Neue Wirbelth. Fische 1835, p. 83.

LARVAL STAGES OF APODES. LEPTOCEPHALI. We know, at least of a number of genera of Apodes (Anguilla, Conger, Congromuraena, Muraena, Chlopsis, Ophisurus, Ophicli- thys, Nettastoma, Synaphobranchus), that they undergo during their development a metamorphosis passing through different larval stages known as Leptocephalus, Tilurns, Hyoprorns. It is probable that, if not all, at least the majority of the Apodes pass through such a metamorphosis, although this metamorphosis may not be everywhere as complicated as f.i. in the atlantic species of Anguilla. The interesting development of these species, first made 399 known by GRASSI and CALANDRUCCIO, has further been studied by ElGENMANN, PETERSEN, JOH. SCHMIDT, HjORT a. O. We may presume that the indo-pacific species of Anguilla have an equal life history, as during the Siboga-Expedition a large number of Leptocepliali in different stages of development were collected, some of which belong probably to the genus Anguilla. The systematic position of others is still questionable. These forms are here shortly described; for further details we refer to the descriptions in : Max Weber, Siboga-Expedition, Fische, 1913, p. 63 — 78. Leptocephali possibly belonging to Anguilla. i.

Description of a specimen with 293 seg- ments: Length 143 mm.; head 8 mm.; eye 1.5 mm.; snout 4.5 mm.; height immediately behind anus 20 mm.; in the region of the gut 23 mm. Distance of anus from point of snout 49 mm., from end of tail 96 mm. In the upper jaw on each side 12 anterior larger, and 8 poste- rior smaller teeth; in the lower jaw 20 teeth, the posterior ones of which gradually become smaller, the most anterior one is nearly horizontal, that in the upper jaw only slightly oblique. Cleft of mouth reaching below middle of eye. Only the posterior nostrils are with certainty descernible as narrow triangular clefts, the base of which is situated superiorly near the frontborder of the eye. Dorsal with more than 300 rays. Dorsal and anal continuous with caudal. Pectorals Fig. 208. Leptocephalus present. Dorsal part of anterior myomeres hiSh> makinS the trunk anteriorly and superiorly gibbous. This gibbosity is enlarged by the excessive development of the extra-muscular gelatinous connective tissue, which forms, immediately behind the head, a kind of strongly compressed rounded lobe overhanging the posterior part of the head. The gut is suspended like a frill on the under side of the anterior third of the body. The small gillopenings are Fig. 209. Head of Leptoceplialus mirabilis Brauer of 143 mm. length. K gillopening. situated ventrally. Eight laterally situated dark patches, formed by submuscular chromatophores; irregular pigment spots along the gut, a diffuse pigment spot near the end of te upper and lower jaw. The single specimen was captured in the deep sea trawl, hauled from a depth of 2477 M. in the Banda Sea, 6° 40' 6" S., I2i'f E.! 408 We suppose that this specimen is a further advanced stage of the Leptoceplialus mirabilis described by BRAUER after a specimen of 71.5 mm. from the Indian Ocean, east of Zanzibar. Besides the above described forms the following Leptocephali have been mentioned from the indo-australian Archipelago. Their description is so short or insufficient, that we draw the attention on them only for completness sake. i. Leptocephalus dentex Cantor. Leptocephahis dentex Cantor, Journ. Asiat. Soc.

It follows from the description of PETERS that this Lepto- cephalid of 157 mm. length from Ambon was in the regressive metamorphosis to a glass-eel, the body of which was already beginning to be rounded. It may be that it is a larval stage of Congrellus Ogilby or Paramyrus Giinther. 3. Leptocephalus ceramensis Blkr. Leptocephahis ceramensis Bleeker, Atl. Ichth. IV. 1864, p. 123.

"The body is strongly compressed, moderately elongate and low; its greatest height, contained about eleven times in its length is situated rather behind the middle. It gradually dimi- nishes in height from that point towards both head and tail in approximately equal degrees. The head is elongate; its length is equal to the body's greatest height. Its upper profile is in the form of a regular shallow arch. The snout is pointed. The space from the snout- extremity to the eye's anterior margin is about three times as great as the diameter of the eye. The eye has a circular contour; its upper margin does not reach up to the upper profile of the head. The posterior nostril is situated a little in front of the eye. The anterior is distant from the snout-extremity four times as far as from the posterior nostril. The cleft of the mouth is horizontal, reaching back to the middle of the lower margin of the eye. The mandible projects a little beyond the upper jaw; its lower profile is straight, retreating with a slightly prominent angle. Teeth in both jaws. Pectoral fins none. The vertical fins show but slight development; the dorsal fin has its origin a little in front of the vent; the caudal fin is pointed. The vent is in front ot the body's "middle, approximately at one third of the length from the fore part. There are some series of closely packed pigmentary spots grouped along the sides of the body immediately above the alimentary canal. There are moreover a few scattered ones on the head in the region of the gillopenings and the snout- extremity. In the collection there is one example of this species, obtained by CAPTAIN VON SCHEELE in 1885 in the Bali Straits. Its measurements are als follows: i) As STROMMAN'S publication is rather rare, we thought it convenient for those who use our book, to reprint his description. 4io Length of body 44 mm.
