INTRODUCTION.

In continuation of the preceding volume of this series, in
which, besides other groups, were treated the. Sz/uroidea,
as first suborder of the Order Ostartophysi, the present or
third volume of the “Indo-australian fishes” contains the remai-
ning suborder of the Ostariophyse: the Cyprinotdea and the
Order Afodes, 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 Synbrancht and some of the Apodes have a wider
distribution in the fresh water of the Archipelago.

The remaining Afodes are inhabitants of the coral reefs, of
the sandy and muddy litoral 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
Synbranchit 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. Popra, 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 Afodes 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 Cyprznoidea 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 Muséum
dhistoire naturelle at Paris and Dr. R. GESTRO, Director of
the Museo Civico of Genova, 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— 4!'/, means, that the length of the head
is contained 4 to 41/, 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 Aye, the length of the Snouz, of the Faws
etc. are compared with the length of the head; thus “eye 4”
means, that its diameter is '/, of the length of the head.

In counting the ‘Scales, under “ZL. 7.” 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.

41
5 Sia he P signifies, that there are 3'/, rows of scales between

6 (7)

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
4th

the lateral line itself is also counted f.i. 2.7. 1 (between
ae

D. and V.), which signifies, that.there are 4'/, 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 2x 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 Gzllmembranes 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,
insthewtext:

In describing the Afodes 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: “nomina 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.

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, Popra, Ph. D.
has called a specimen from river Mahakam, Borneo, He/gia 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.

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.

Te

In the single specimen described by Miss Popra Ph. Dr.
(see note on 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 HZ. ocellata. As also HZ. ocellata is founded
on a single specimen, we think it possible, that A. ocellata
and H/. wassinki belong to one and the same species.

Note. We have included JV. saravacensis in the synonymy
of WV. 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 JV. fasczatus
(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 Mc Clell.
whitout giving any reason for this definition, we believe that
they belong to Nemachilus fasciatus C. V.

Dr. GESTRO, Director of the ,Museo Civico” of Genova has
been kind enough to send us two typical specimens of J/odz-
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 alla regione prae-
orbitale” and otherwise there is no difference from Memachilus
fasciatus.

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 WV. fas-
ceatus (C. V.). The only differences are, that the caudal fin is
feebly notched in WV. olzvaceus, deeply emarginate in WV. fasciatus,
that in the former the ventrals reach the anus, which is not
the case in JV. fasczatus. The latter species has also a series
of black spots on the dorsal rays, which are wanting in
NV. olivaceus.

We have placed this species under the doubtful ones, as
we doubt, that E. vON MARTENS (Preuss. Expedition nach

Note:

BLEEKER described (Nat. Tijdschr. Ned. Ind. II. 1851,
p- 435) a Cobdztis 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 Codztechthys: “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. Codztis barbatuloides Blkr.” This chang-
ement of his opinion about the suborbital spine is explained
im; ichthe Arch; Prodom. Il) Cyprini;, 1660, p.$2. In his) Atl.
ichth. III. 1863, p. 14 the species in question is called J/s-
gurnus barbatuloides Blkr. As also the number of barbels is
uncertain and BLEEKER himself says: “l’espece meérite d’etre
examiné de nouveau,” we only draw attention to it, but dare
not to give a description.

3. Fam. CYPRINIDAE.

Head and body compressed, exceptionally depressed. Pect-
orals and ventrals only in few cases horizontally inserted, only
one of their outer rays simple. No spine before or below eye.
Eyes with a free orbital margin, which may form a gelatinous
eyelid. Dorsal short or long, its origin before, above or behind
that of ventrals; anal short or long, its origin below dorsal
or behind it. Mouth inferior or terminal, its upper border
formed by the intermaxillaries only. Never more than two
pairs of barbels: a rostral and a maxillary pair, one or both
may be absent. Arrangement of lips and jaws and their covering

moderate or small. Lateral line generally complete. Gillopenings
generally wide, but gillmembranes broadly united with isthmus.
Pseudobranchiae present. Pharyngeal teeth in one, two or
three series, absent only in Gyrinocheilus. Airbladder divided
into two portions, the posterior of which may be reduced, the
anterior in indo-australian species not enclosed in bone.
Distribution: Fresh water of Europe, North America,

Length 120 mm. [Type of the species in the zoological Museum

Habitat. Sumatra (Atchin: Lake Tawar!), collected by Mr.
Vv. D. WERFF. We received this new species through the kind
intervention of Lieutenant Colonel Dr. A. J. SALM from Mr.
Vv. D. WERFF, who got them from Laut Tawar, a large lake
situated in the interior of Atchin (Gajo-territory). He had the
kindness to inform us that the natives assured him that this
fish is not known from any other waters. His collection con-
tains 6 specimens of 98—120 mm. which are called by the
natives Ikan l’as. He informs us that they are only caught
during the north eastern trade-winds, which is the wet season.
In the collection are 4 specimens of about 85 mm. which are

65

called by the natives “Ikan depeq’’. They are not seen during
the north eastern tradewinds, but only during the dry season
and even then they appear only in great numbers during the
“depéq”’-winds, which are blowing with great strength during
a few hours. Such depeq-winds, during which the depeéq-fishes
appear, are blowing in the dry season (April—October), about
4—6 times in each month. Nothing is said about 3 other
fishes, 58-66 mm. which carry the name: “Ikan relo”’, from
the same lake, which belong without question to the same
species. Our opinion is that these are the representatives of
three generations of the same species. It may be that they
are living in deeper water and that at least the ikan depeq
is forced to come to the surface in consequence of the depeq-
winds.

Note: We unite with the present species the specimens
described by BOULENGER as R. calliura from Senah, Sarawak,
Borneo. We have seen them in the British Museum as also
identical specimens from river Sebuku, North East Borneo,
belonging to the Museum in Buitenzorg, Java. The only difference
is that in R. ¢rélineata the black blotches on the lobes of the
caudal are subterminal, in 2. calliura they cover also the tips
of the lobes of the caudal. This difference is not a geographical
one, as VAILLANT has described specimens from Borneo with
subterminal black blotches on the caudal lobes.

7. Rasbora dorsiocellata Duncker.

Differs from the preceding species in having only 10 scales
in frout of the dorsal and in wanting the black bands on the
caudal. At the other hand the dorsal is deep black in the
middle of its anterior part. Measurements, position of fins and
colouring are equal for the rest in both species, when specimens
of equal length are compared. In the diagnosis of this species
DUNCKER says: “Lin. lat. unvollstandig’’. This must be a
misprint, as the L.1. in clearly indicated on the figure accom-
panying DUNCKER’s description and as it is’ very distinct in
typical specimens, which Dr. DUNCKER kindly sent us for
examination. Length about 45 mm.

GUNTHER says: (Cat. Brit. Mus. VII. p. 194) “One might
be tempted to regard R. eznthoveniz Blkr., as distinct, if the
figure given of it be alone consulted. However, it appears from
his description that normally the black band is not so much
curved as represented; and the specimen sent to the British
Museum is absolutely identical with 2. danzconzus’. This must
be an error. We have at our disposition a good specimen
which we received through the kindness of Dr. ANNANDALE
from Calcutta under the name of FR. daniconzus and besides some
specimens from Ceylon, kindly sent to us by Dr. G. DUNCKER
from the Museum in Hamburg. These specimens agree with
GUNTHERS description, they differ from ezuthovent by having
9 in stead of 7 rows of scales between the lateral lines,
counted over the back, by having the pectoral equal to head
without snout, whereas the pectoral of ezuthovenz is longer
than the head. There are 14—15 scales between the head and
the dorsal, in ezuthovent 12—13. R. daniconzus has been menti-
oned by different authors from the Archipelago, but as GUNTHER
has united ezuthoveni with it, it is not sure if those authors
have had ezuthovent or a species which could be identified
with R. daniconius from India. Only VAILLANT (Nouv. Arch.
Mus. (3) V. 1893 p. 86) gives a description of two sets of
specimens, which he believed to be R. daniconius. One set,
containing specimens measuring 33—64 mm. belong probably
to R. trilineata. About the other set, containing specimens of
163 mm., we are not sure.

1) The, occurrence of this species in lake Galela in Halmahera (STEINDACHNER
l.c.) is Without question erroneous and a mistake in KiUKENTHAL’s collection or
in using it. KUKENTHAL himself says (Forschungsreise in den Molukken and
Borneo 1896, p. 152), that he found only one species of fish in this lake, which
is, according to STEINDACHNER, Lleotris macrolepidota Bloch. On page 126 he
pretends to have found “ein paar Cyprinoiden”, in the rivers near Oba and Patani,
Halmahera. This must be also erroneous as STEINDACHNER found in the collec-
tion from this rivers, besides some true marine or brackish water species, only
Kuhlia marginata (C.V.), which may be taken for a Cyprinoid.

The specimens, except those from Siboga, which were col-
lected by Mr. ED. JACOBSON, after whom we have taken the
pleasure to name this species, were first described by one of us as
R. daniconius. Our diagnosis shows that it differs from that of
the indian species, which is known, for instance, by the des-
cription of GUNTHER as R. daniconius. For differences see

Q2

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).

2. 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'/, 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

According to our opinion Barynotus lagensis Gthr. does not
belong to this genus, but belongs to Barédus s. lat., where this

The above description is in accordance with that of BLEEKER
given for Rohita vitiata; the description of CUVIER & VALEN-
CIENNES is too superficial to be sure that it is the same as
BLEEKER’s species.

BLEEKER distinguishes from this species as KR. ¢riporus

specimens, which have one scale less beneath the lateral line,
1

thus: a and by having a black spot anteriorly on the base
53
of the dorsal. In our material we find two specimens with the
same characteristics and besides characterized by having only
3'/, series of scales between lateral line and origin of ventrals,
but otherwise identical with vztéatus. If this form from Borneo
and Sumatra is really a good species, its synonymy would be:

In our material of 29 specimens from Djambi, 20 are quite
in accordance with the description of O. vzttatus. Nine others
differ in having a less number of scales between lateral line

42—5

and dorsal, for their linea transversalis is 1 . Besides they

6}
are characterized by a black band on the outer upper and
lower margin of the caudal and by a black spot anteriorly on
the base of the dorsal as is also described for O. ¢riporus.
Two specimens from Putus Sibau on the river Kapuas, Borneo,
are identical with the lastnamed g specimens. We propose
to call them provisionally :

1

their linea transversalis is: a and as they have 3!/,—4 series
52

of scales between ventrals and lateral line. Moreover O. bellus
has a black spot at the end of the lateral line. The 8 series of
small spots, described by Miss POPTA, may sometimes also be
found in small specimens of O. vz¢tatus. O. bellus Popta attains
200 mm. and is found in Borneo (river Bo), where it is
called Piit.

Miss PopTa described a specimen of 189 mm. from the
river Bo, Borneo, as Barbus hampal var. bzfasciata, distinguished
by a second dark band running in the middle of the caudal
peduncle. She observes, that this variety grows to a length of
500 mm. according to the collector Prof. A. W. NIEUWENHUIS.
We suppose that this is the partial retention of an infantile
coloration, for we have a specimen of 36 mm. from Djambi,
Sumatra, which has a very distinct black vertical band between
origin of dorsal and ventrals, a much less distinct one in the
middle of the caudal peduncle, a curved band behind the
opercle, a black band through the eye, a faint one at the base
of the caudal and a faint blotch at the origin of the anal.

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 differenceg 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. valenczennesi, which he himself afterwards con-
sidered to be the same as &. armatus. Principally on account
of the high and short caudal peduncle of our specimens, through
which characteristic they differ from 4. vepasson, 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

165

think this of great importance, as GUNTHER (l.c.) says that
one of the typical specimens of BLEEKER had also only 2 barbels.

1) in the Atl. Ichth. III. plate CXXXVI. (Cypr. XXXV) the figures of
Puntius schwanefeldi and C. macropus are interchanged; this explains the mistake
of Vinciguerra (Ann. Mus. Civ. Genova XIV. 1879, p. 389), who wrongly iden-

Upper profile nearly- straight from tip of snout to origin of
dorsal. Caudal peduncle compressed, its least depth about 1'/,

Head compressed, moderately long, and upper profile hori-
zontally oblique and straight. Snout rather long and obtuse.
Eye large, longer than deep, a little anterior and high. Pupil
large, vertical. Mouth inferior and terminal, upper jaw about

Tongue little free or distinct. Mandible inferior, not extending
forward opposite tip of upper jaw. Upper jaw protractile. A
small pointed maxillary barbel at corner of mouth. Nostrils
adjoining, close in front of upper orbita! rim. Preorbital long,
about ‘/, of length of horizontal orbital diameter. Interorbital
space flattened, a trifle concave medianly.

Gill-opening lateral, not extending quite as far forward as
posterior margin of orbit. Rakers 3 + 5, soft fleshy slender

back for about first fifth of length of ventral. Ventral with
first branched ray longest and reaching anal.

Color in alcohol brown, lower surface paler and with traces

regular in disposition, so that longitudinal series are formed,
and several persisting even below lateral line, but lowest much
paler than those above. 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. szaja. When FOWLER writes: ‘it agrees with
BLEEKER’s description of Capoéta enoplos, but his figure (Atlas
Ichth. 1II. 1863, p. 82, Pl. (27) 128 fig. 2), agrees with Sumatran
examples of Cyclocheilichthys staja, 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
Larbus enoplos Bleeker, which is a quite different species.

and with an other less distinct one in the middle of the root
of the caudal, preceded by a faint dark longitudinal band.
This band develops out of a series of more or less confluent
black spots. In still younger specimens this series is represented
by four or three widely separate black spots, they have besides
a black spot at the base of the anal, which disappears later
on. Large specimens often show no markings at all, they may
also show nuptial epidermoidal pearls or violet spots in the
centre of each scale. Length about 170 mm.

GUNTHER mentions |.c. among the localities of Barbus bino-
tatus “t young Amboyna. From the collection of Mad. Ida
Pfeiffer.’ This is without question erroneous, as no Cyprinid
occurs in Ambon.

Note: We have included Larbus palavanensis Blgr., the
type of which we have seen in the British Museum, in the
above list of synonyms of Punteus dinotatus (C.V.), as we consider
it to be a colour-variety of that species, where the markings
of the immature (see our figure 74, p. 189) have been retained.

it differs by having one scale less between lateral line and

Note. BLEEKER has founded his Puntius (Barbodes) koitlo-
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 17/,—1°/, times in javanicus. Moreover
the body is higher (height about 3 in length with caudal) and
the dorsal profile very much concave at nape. GUNTHER
(Cat. Brit. Mus. VII. 1868, p. 119), who had the two typical
specimens at his disposition, says: “I do not think that B. ko7-
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 GUNTHER 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.

from river Kwantan, Sumatra, Fortunately he gives an ample description of his

single example. This description shows, that he had not a specimen of B. proc-

his description: ,Liange der Brustflosse gleich der gréssten Korperhdhe oder

B. proctozysron Blkr. is also mentioned by v. MARTENS (Preuss. Exped. Ost-
Asien I. Zoologie, 1876, p. 402), from Sintang, Borneo. He puts a query with the
specific name. Now B&B. proctozysron Blkr. is very easy to recognise by its strongly
dentated anal spine, a character unique among Aardini, 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,

Founded on one specimen of 49 mm. length from Java

Tylognathus schwanefeldii Giinther, Cat. Brit. Mus. VII. 1868, p. 66.

If this is really a distinct species, it differs, according to
BLEEKER and GUNTHER, from 7. falcifer by having the height
of the body equal to the length of the head. According to
BLEEKER the height of the head goes 17/,—19/, in its length
in 7. schwanefeldi, and 1'/, 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.

Specimens of both species of BLEEKER’s collection in our
possession, are in too bad state to controle the above statements.

a diffuse dark band, dissolving on the tail in three to four
subsequent large black blotches. Dark brown clouds on back
and base of dorsal and caudal. Lower half of dorsal with an
oblique brown band, a longitudinal one in the middle of the
caudal. Length about 90 mm. [After KNER, not seen by us].

This species was placed by KNER with a query in the
genus Pachystomus. GUNTHER mentions it as a Barbus and
says: ,said to be from Java, but evidently allied to the east-
asiatic types of Barbus.” KNER himself gives as habitat: ,von
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).

Elongate, anteriorly and posteriorly compressed, head depres-
sed and flattened above. Snout bluntly rounded, very prominent.
Mouth inferior, very small and extremely protractile, provided
with a pair of barbels at its corner. Dorsal long, with 16
branched rays, its origin before that of ventrals. Anal short,
far behind end of dorsal. Ventrals and pectorals horizontal ;
only one of the outer pectoral rays simple. Caudal deeply
emarginate. Scales small, multiradiate; lateral line present.
Branchial openings ending below base of pectorals. Gillmembrane
broadly united to isthmus. Pharyngeal teeth unknown.

Distribution: The single known species from fresh water
in Borneo.

Fig. 97. Ellopostoma megalomycter (Vaill.). (After VAILLANT).

Height of anal slightly less than length of head. Ventrals equal
to head, separated by 8 scales from lateral line, surpassing
anus. 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 51 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
Apertoptus Rich. (see p. 238). We think there is no reason to
do so. We therefore use for it the name “//opostoma, which
VAILLANT proposed in case his fish should appear not to be
an Apertoptus.

In the second place VAILLANT brings Aperzoptus and there-
fore also Ellopostoma in the family Codztzdae. We doubt the
correctness of this view, although we are not able to say, to
which family of Cyprznzdae these probably young fish belong.

VALENCIENNES mentions this species from ‘la riviére 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 Ladeo.

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

»Spirits, they were thrown out and lost. The general aspect
»of the fish is that of a slender Ga/axias, but there are no
,yteeth on the jaws. The orifice of the mouth is a narrow
yvertical oval, which is restricted on the sides by membranous
»processes. The figure is of the natural size.

eit a Ditalt<.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 El/opostoma
megalomycter (Vaillant) on pag. 237.

2.4—4 in head, reaching in young specimens nearly to hind-
border of eye, in older ones to the hindborder of the eye or half
diameter of eye behind it. Head shorter than its distance from
dorsal, shorter than or equal to half its distance from anus and a
little longer or shorter than the distance between origin of
dorsal and anal. Pectorals 2.7—4 in head. Breadth of snout at
base equal to or a little more than its length. Tail longer than
head and trunk. The intermaxillary and vomerine teeth forming
a band, which — so far as it is in reach of the maxillary teeth —
gradually tapers posteriorly from 17—18 rows of teeth ante-
riorly to about 7 rows posteriorly. There upon it often tapers
abruptly and ends lancet-shaped, at a distance of '/, of its
length or less from the level of the end of the maxillary band
of teeth. These teeth form a band of 10—16 rows anteriorly,
which only slightly tapers posteriorly. It is narrower than the
vomerine band and separated from it by a groove. The mandi-
bulary band of teeth is alike. Colour of alcohol specimens light

Only one specimen known, which when BLEEKER received
it, was in a very bad state and is now preserved in the British
Museum. 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. GUNTHER says l.c. 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. hadbenata.” But OGILBy rightly
remarked l.c. p. 286: “Dr. GUNTHER’s suggestion that this
species “ “may be identical with C. hadbenata’’” cannot be ac-
cepted if BLEEKER is correct in describing the jaws as of equal
length, the snout as 4'/, 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.”

snout damaged, where from its anterior nostrils are not visible.

specimen of BLEEKER in the Leiden Museum this is certainly not the case; they
are acicular as also GUNTHER calls them in his diagnosis of the genus.

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.

situated above the second third of cleft of mouth. Posterior
nostrils a long slit, longer than eye and situated below its
hindmost third and behind it; anterior nostrils a short tube
directed backward, at the edge of the upper lip, below front-
border of eye. 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—91 M. depth!.

1) 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.

1) It is possible that the curve upward formed by the snout and downward
by the lower jaw is only a consequence of the manner in which the specimens
died or were preserved. We offer this opinion with regard to the specimen of
Nemichthys scolopaceus, which was taken alive and has been described and figured
by Rouse (Ann. Inst. océanogr. I. fasc. 6, 1910). In this specimen the jaws
are straight (see p. 329).

that this species is identical with Serrivomer beani Gill & Ryder,
(Proc. U.S. Nat. Mus. VI. (1883) 1884, p. 260). But S. deani
has only 138 rays in the anal and its height is only 29.7 in
the length according to GILL & RybDeEr. If this difference
from S. sector is constant, we are of opinion that both species
are valid. Otherwise the name deanz has preference as being
the older.

compressed; the pointed snout at its apex with a barbel-like
filamentous appendage and 3 similar ones on the symphysis
of the lower jaw. Eye small, covered by skin. Anterior nostrils
produced into tubes ending with a foliaceous appendage, the
margin of which is slit; posterior nostrils a rounded opening
shortly before eye in the level of its upper border. Cleft of
mouth reaching far behind eye, closing completely. Pectorals
absent. Dorsal, anal and caudal confluent, well developed,
covered by thin skin only. Origin of dorsal on top of head
far before gillopenings. Tail extremely elongate, more than

1) This description is not in accordance with that of BLEEKER, who says,
that in the maxillary the teeth are in 3 series and on the vomer anteriorly
in 2 and posteriorly in one series. His figure gives clear representation of this
statement.

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 witha few
round or irregular spots. Length 750 mm.

In the maxillaries a row of 12—20 compressed teeth, the ante-
rior ones the largest. In young specimens anteriorly an inner
row of 3—1 large, depressible teeth. Intermaxillary plate with
a peripheral series of 10—16 teeth, which are larger than
those of the maxillaries and with a median series of 3 fang-
like teeth. Vomer with 10 or less smali teeth in an irregular
series. Mandibulary teeth 18—30, compressed, pointed, the
anterior ones longer and more irregularly placed, the posterior
ones in a single row. In the variety fimérzata the colour is
reddish brown, with several irregular longitudinal rows of black
round or irregularly oval spots, which are generally not much

378

larger than the eye; those on the head are smaller and may
be wanting. On the tail they are often also arranged in trans-
verse rows, giving a more or less striped appearance to this
part. Dorsal and anal often with a light border. These spots
may partly be confluent, in which case the fish is yellowish,
densely reticulated and marmorated with brown (JZ. agassizz).
In the variety wxdulata the spots have still more gained in
extension and the groundcolour is blackish, lighter on the
belly, with a wide network of more or less dendritic white
or yellowish lines, which are more numerous on the head,
giving to this part a mottled appearance. Length 1500 mm.

Note. GUNTHER (Cat. Brit. Mus. VIII, p. 117) united this
species with M7, nudzla Kich., but afterwards (Siidseefische, l.c.) he
separated it again, as no transitions between the typical colo-
ration of the head of JZ. chzlospilus and that of AW. nudila 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 MW. zonzpectis (Seale), 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.

in length of head. Tube of anterior nostrils nearly thrice in
length of snout. Dorsal rather low, commencing above gill-
openings. Teeth conical, acute, 14—16 small ones in maxillaries,

maxillary plate a peripheral series of about 15 teeth, most of
them much longer than those of the maxillaries and mesially
a series of 2 or 3 fang-like ones. A single series of 5 or more
small teeth on vomer. Mandibles with a series of closely set,
rather short compressed teeth, about 22 on each side; near

Note. Only four specimens, all of small size, are known of
this strikingly coloured species. GUNTHER (Fische der Siidsee,
Heft IX. Ig9g10, p. 413) united it with JZ. 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.

Habitat: Waigeu and Island Rawak [QUoy & GAIMARD]. —
Samoa, Tahiti, Raiatea, Hawaii.

Note: JORDAN & SEALE (l.s.c.) have united AMWuraena canina
of Quoy & GAIMARD (I. s.c.) with Euchelynassa 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
tubulées’”’. 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 ‘uniformément noiratre’” makes it plausible,
that the opinion of JORDAN & SEALE is right.

Note. 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. t2grina
(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

1) BLEEKER has shown (Versl. Akad. Amsterdam XV. 1863, p. 462) that
Kaup has confounded Gymnomuraena marmorata and Gymnothorax polyuranodon
under this name.

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.

of G. concolor, but its tail is shorter than head and body; the
measurements are: head Ig, trunk 63, tail 76. We are not
sure where to place this specimen, the dentition of which agrees
with that of G. concolor or of the young of G. marmorata.

LARVAL STAGES OF APODES.
LEPTOCEPHALI.

We know, at least of a number of genera of Apodes (Anguilla,
Conger, Congromuraena, Muraena, Chlopsis, Ophisurus, Ophich-
thys, Nettastoma, Synaphobranchus), that they undergo during
their development a metamorphosis passing through different
larval stages known as Leptocephalus, Tilurus, Hyoprorus.

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 Anguzlla.

The interesting development of these species, first made

oo

known by GRASSI and CALANDRUCCIO, has further been studied
by EIGENMANN, 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 Lepéocephali in different stages of development
were collected, some of which belong probably to the genus

the development of the olfactory pit and the loss of larval
teeth show that the specimen belongs to the last metamor-
phosing stage before becoming a glass-eel.

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
present. Dorsal part of anterior myomeres
very high, making the trunk anteriorly and

407

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

We suppose that this specimen is a further advanced stage
of the Leptocephalus 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 Leptocephal
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.
Leptocephalus dentex Cantor, Journ. Asiat. Soc. Bengal XVIII. (1849) 1850, p. 1315.

Described after a specimen of 41/, inches length from Pinang,
found in the stomach of Fohnius diacanthus.

Helmichthys oculus Peters, Monatsber. Akad. d. Wissensch. Berlin, 1866, p. 525.
Helmichthys oculus Max Weber, Siboga-Exp. Fische, 1913, p. 65.

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 Gunther.

“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
fang as trom the: posterior nostril. The cleft of the mouth: 1s
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:

teeth, which they equal in size. Man-
dibulary teeth still stronger, arranged
in a single series, which broadens near
symphysis into a pluriserial triangular
figure. Gillmembranes united, free from
isthmus. Gillopenings forming a single

1) As in Java the three languages: javanese, sundanese and malay are spoken,
we have accordingly placed behind the indigenous names (Malay.), (Sundan.) or
(Javan.). In naming a fish the malay people use as a rule “ikan” = fish before
the special name. In most cases we have omitted “ikan”.
