INTRODUCTION.
The present volume is the fourth of the series of volumes
devoted to the knowledge of the fishes of the indo-australian
Archipelago and the third in which we endeavour to give a
concise description of all the fishes at present known to inhabit
the seas and freshwater of that Archipelago and also to show
their distribution through this area. We have already defined
the character and geographical limits of this area in the
Introduction to the second volume.
In the present volume the orders of Heteromt, Solenichthyes,
Synentognathi, Percesoces, Labyrinthici and Microcyprini are
treated.
The material at our disposal has already been mentioned
in the Introduction to the former volumes, so that we have
only to add the following new additions.
_ In acknowledging our obligations to contributors of valuable
material, we have to mention the following collections:
From Sumatra a collection made by Jonkheer F. C. VAN
HEURN at Deli.
From New Guinea an extensive collection made by Jonkheer
W. C. VAN HEURN in the Mamberamo-river and its tributaries.
In former volumes we had the opportunity to thank Dr. J.
C. KONINGSBERGER for his interest and collaboration in the
present work which was published with his aid.
Dr. W. M. DOCTERS VAN LEEUWEN, his successor as Director
of ’sLands Plantentuin at Buitenzorg, Java, has shown the
VI
same interest. We are under particular obligations to him and
to Dr. A. L. J. SUNIER, Head of the Government Laboratory
for Marine Investigation at Batavia and to Dr. K. W. DAm-
MERMAN, Director of the Zoological Museum at Buitenzorg,
for sending us for study the fishes in the institutions under
their control.
We are also indebted to Mr. B. A. BEAN (Washington),
A. R. Mc CuLiocuH (Sydney), Dr. G. DUNCKER (Hamburg),
H. W. FOWLER (Philadelphia), Dr. J. PELLEGRIN (Paris), Dr.
F. SARASIN and Dr. J. ROUX (Basel) for valuable informations
concerning species in the collections under their charge.
Again we have to thank Prof. Dr. E. D. VAN OOkT and
Miss Dr. C. Popra for giving us every facility to study the
fishes in the Leiden Museum, especially the specimens of
BLEEKER’s collection,
We beg to express our hearty thanks to Mr. C. TATE REGAN
for his kind help in studying some fishes in the British Museum
during the preparation of this volume. Also to Dr. V. PIETSCH-
MANN when comparing some types in the Vienna Museum.
For the benefit of those who make use of this volume we
repeat the technical informations, given in the Introduction to
the former volumes of this series.
“In describing the fishes we understand by Length, in the
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 4'/, times in the length.
Fleight 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 Hye, the length of the Snout, 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 ‘Z./.” is given the number
of scales, with or without sensory organs, between the head
Vil
and the caudal fin or, in most cases, between that fin and
the upper corner of the opercle.
1
Et 1G signifies, that there are 3'/, 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
43
the lateral line itself is also counted f.i. Z.z. 1 (between D. and V.),
I
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 Fz 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 G7llmembranes 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.
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 quoted as the
author of the species and his paper is quoted in the first place,
when there is no stringent reason to do otherwise.
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-Aus-
tralian 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
Vill
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.”
Finally there remains for us the pleasing duty of expressing
our sincere thanks to Mr. J. F. OBBES, to whom we are indebted
for most of the figures, which illustrate this volume and to
Mr.-C. PELTENBURG, ~head, of. the: firme =H. J. BRILE@ised au
Leiden for his interest in publishing this volume.

tropical’ America (California, Mexico) and to Japan and Australia.
Remark. Of this species, which is often confounded with
the preceding one, larger specimens are better represented
in collections from our region than of /. vz/losa Klunz. One
gets the impression, that, when young, both are living in the
shore water, where F. petzmba Lac. grows to a large size, and
is easily captured, while /. vz//osa Klunz., when growing larger,
lives outside the shore water and seems therefore to be rarer.
2. Fam. MACRORHAMPHOSIDAE.
Physoclists. Body oblong or elevated, compressed. Head
produced into a long tube formed by the prolonged bones of
the mandibulary suspensorium and the anterior prolongation
of the praeoperculum. The other opercular bones are well
developed. Of the true mouthparts the intermaxillaries are weak,
the maxillaries fairly broad, the mandibles well. developed, all

the bones are without teeth as also vomer, palatines and
pterygoids. The parietals are wanting. No lateral line; lateral
line canals on head present. Head and body all over covered
by small, rough scales, formed by a scaly plate in the epidermis,
with the hindborder more or less toothed and with one or
more keels on its surface. Each scale is connected by a stalk
with a bony plate imbedded in the cutis. Besides the trunk
is armoured with large bony plates, which make it stiff and
immoveable and which are partly hidden by the scales (see Fig. 6).

The ventral part of this armour, reaching from the isthmus to the
anus, broken only by the groove for the ventrals, produces the
sharp ventral keel. The dorsal cuirass is formed by 2 rows of
bony plates, the lower of which are partly connected with the
transverse processes of the vertebrae. The 5 anterior vertebrae
are elongated and much stouter than the others. Spinous and
soft dorsal continuous with or separated from each other, or both
are connected by a series of short, isolated spines. Anal as
also the soft dorsal are of moderate extent. Ventrals small,
abdominal, without spine. Pectorals inserted more or less midway
the height of the body. Their 4 pterygials are stout but short.
The cleithrum is suspended from the posttemporal, which forms
part of the skull. Four branchiostegals. Four complete pecti-
nate gills; pseudobranchia large; gillopening wide.
Small fishes living in temperate and tropical part of Atlantic,
Indo-Pacific and Mediterranean.

Habitat: Ambon. — Samoa, Hawaii and according to
REGAN East Africa, Indian Ocean, China and the Mediterranean.
Note: GUNTHER doubted very much that this fish came from
the East indian Archipelago as asserted by PALLAS, as it had not
been recognized again after his description. But PALLAS says
that he received the fish from J. A. SCHLOSSER, who commu-
nicated it to him together with Cadlonymus sagitta Pall. and
Fistularia paradoxa Pall. (Solenostomus paradoxus Pall.).
SCHLOSSER got these fishes from Ambon and it is quite well
known, that the two last-named species really occur near that
island. So it may be allowed to conclude, that also the Cen-
triscus velitarts of PALLAS came from that locality. This con-
clusion is strengthened by the fact that Macrorhamphosus
velitaris is now also known from China, Samoa and Hawaii.

3. Fam. CENTRISCIDAE.
Physoclists. Body elongate, extremely compressed with scharp
ventral edge. Head produced into a long tube with the mouth
terminal, small and toothless. Trunk ending posteriorly in a
long strong spine with or without a movable spine at its end.
Below it are situated 2 dorsal fins, a spinous dorsal, close to
the strong spine and a soft one directed downward. The
longitudinal axis of the short, movable tail is deflected at an
obtuse angle from that of the trunk and terminates in a short
caudal. The anal lies close before it. Body for its greater part
transparent and encased in a dorsal and ventral exoskeletal
unflexible cuirass. The former is composed of two alternating

rows of 5 bony plates, each connected by suture. The lower
(or lateral) row of plates, across which runs the lateral line, is
connected with the vertebral column. Behind the fourth plates
of the upper row and wedged in between the fifth plates of
that row is situated an unpaired plate covering the base of
the terminating strong spine. In Agolzscus there is another
small, unpaired endoskeletal plate anteriorly in the middle line
of the back between the posterior ends of the first pair and
the anterior ends of the second pair of plates of upper row.
The ventral cuirass consists of a row of 13—15 exoskeletal
plates. Anterior 5—6 vertebrae elongated, the transverse pro-
cesses of the second to fourth or fifth connected with the
dermal plates. In the skull the parietals are wanting; the true
mouthparts are small. The prolongation of the snout is pro-
duced by the prolonged mandibulary suspensorium and by
the praeoperculum developed into a thin, transparent plate,
anteriorly attached to the prolonged quadrate. Other opercular
bones well developed. The ventrals are abdominal, more or
19
less rudimentary, inserted on the 8th plate and coalesced along
their inner margin; they have a spinous and 4 soft, but un-
articulated and unbranched rays, which may be prolonged in
males (of dAeoliscus stri- —— eit

1) In the list of fishes collected by Semon (MAX WEBER in Semon, Zool. For-
schungsreise Australien etc. V. 1895, p. 268) one of us named also Amphisile
scutata (L.) from Thursday Island. A. R. Mc CuLiocnu (Biol. Results “Endeavour”
III. 1915, p. 105) has quoted this statement under the synonyms of Cendriscus
cristatus de Vis, without having seen the specimen. The distinguished australian
ichthyologist was probably under the impression that a specimen of Cev¢riscus
from Thursday Island must belong to the australian species C. cristatus de Vis.
This is an error, the Thursday Island-specimen is Centriscus scutatus L. Never-
theless we thought it advisable to enlist C. cvis¢atus de Vis as it is not impro-
bable that this species will be found along the south coast of New Guinea.

5. Fam. SYNGNATHIDAE.
Physoclists. Body elongated, angular or laterally compressed
or rounded; tail long; head slender,generally with a produced
tube-like snout, with a terminal, oblique mouth, bordered by
the small intermawxillaries, maxillaries and mandibles. All these
bones withouth teeth as also the vomer, palatines and ptery-
goids. Posttemporal suturally united to the skull. No supra-
cleithrum; cleithrum firmly united with the transverse processes
of the two anterior vertebrae. Of the 4 pterygials the distal
parts are fixed between dermal scutes. Pectorals and scapular
arch may be wanting. The skin is completely armoured by bony
scutes (shields or plates), arranged regularly in series, and forming
rings (annuli) round the body, which, with exception of the
first, correspond to the vertebrae. Of the vertebrae the three
anterior are immovably jointed together. One dorsal (by
exception absent) of soft rays only, generally opposite to the
minute anal, which usually is present. Caudal small, when
absent the tail is more or less prehensile. Pectorals small or
wanting; ventrals none. Two nasal openings. Opercular bones
present, operculum large. One branchiostegal, distally divided.
Four complete lobate gills, pseudobranchiae well developed.
Gillopenings reduced to small dorsal apertures, the margin of
the gillmembranes being fused with the isthmus and the body.
The male takes charge of the eggs. They are united into
a plate loosely attached to the abdominal skin of the male,
31
or the single eggs are fixed to the skin of the abdomen or
to the ventral surface of the tail and isolated in cutaneous
cells from their neighbours. The egg-plate is uncovered or the
eggs are enclosed in a pouch on the abdomen or on the tail,
formed by two folds of the skin, the free borders of which
remain at some distance from each other or meet in the median
line and may even coalesce. In the last case they open some
time after hatching, when the young are released. These folds
are reduced after the breeding season or they are permanently
closed to a sac with an anterior small opening (Hzppocampus).
The skin-folds often also contain bony plates derived from
the body-rings, or these plates alone form the pouch-folds.

from outside, s superior, 7z median, 7 inferior lateral plates, sc scutellum,
pm praenuchale, 7 nuchale, c/ cleithrum, # pectoral, 7 jugular plates,
¢ cover plate. (After JUNGERSEN).
Specialised fishes of small size living in the shore-water of
tropical and temperate seas; many species entering fresh water.
They are bad swimmers, moving about in a vertical position
by undulating movements of the dorsal. Those who are wanting
a caudal, are able to bend the end of the tail and to attach
themself by it to seaweed or other objects.
Remarks: The discrimination of genera and species is in
the first place based on differences in the dermal armour,
constituted by bony scutes (shields or plates), arranged into
succeeding rings (annuli).
In the praedorsal region each ring is composed of 7 plates:
33
Ohe unpaired: the ventral plate (scutum abdominale) and 4
paired, the superior, median and inferior lateral plates (scuta
lateralia superiora, media et inferiora); in most genera there
are small zutermedial scutes (scutella) between the lateral scutes.
Only the first or scapular ring of DUNCKER is more compli-
cated. The first ring consists of the “Skapularschild’” of
DUNCKER = “dermal part of the clavicle and the coverplate”’
of JUNGERSEN and DUNCKER’s ‘Axillarschild” = JUNGERSEN’s
median lateral plate of the second ring and in the third place
of JUNGERSEN’s “jugular plate” = “Infrascapulare”’ of DUNCKER.
The praenuchal plate (shield), between the occipital crest of
the skull and the first spinous process and the nucha/ plate
(shield) between the spinous process of the first and second
vertebrae are possibly modified interspinous bones.
The scapular ring of DUNCKER consists, according to JUN-
GERSEN, in reality of the elements of two rings. But as the
second ring, that behind the pectorals, is the first ring of typical
conposition, we follow DUNCKER and count both, for conve-
nience sake, as the first ring of the trunk (cfr. Fig. 16).
The postdorsal or tail rings contain only the paired scuta
lateralia superiora et inferiora.
The scuta of the same name are antero-posteriorly linked
together by a kind of articulation. Each scutum (shield) is
provided with a median longitudinal keel, and as the keels of
the succeeding scuta fit together, the succeeding keels produce
the longitudinal cristae of trunk and tail, the number of which
corresponds with the arrangement of scutes in trunk and tail.
We distinguish therefore on the trunk the unpaired crista abdo-
minalis trunci, which terminates on the last or forelast trunk-
ring, the paired cristae laterales superiores, mediae et inferiores
trunci and on the tail the cristae laterales superiores et inferiores
caudae. In the subdorsal region, where generally the last
trunk-rings and the foremost tail-rings carry the dorsal fin, the
paired keels of trunk and tail are continuous or they are in
different way discontinuous. There exist, according to DUNCKER,
the following modifications:
I. Superior cristae of trunk and tail continuous.

cristae of trunk and inferior cristae of tail continuous... fig. 17, n® ft.

Of much taxonomical value are the modifications how the
parental care is executed in the males. We have indicated
above that the eggs are carried open or in pouches of different
construction on the ventral surface of the abdomen (Gastro-
phort DUNCKER) or subcaudal (Uropherz DUNCKER).
DUMERIL (Hist. nat. Poissons 1870, p. 585) has already
expressed the opinion, that ‘le véritable classement” of the
Syngnathidae must be based on the brood organ of the male;
GUNTHER (Cat. Brit. Mus. VIII, 1870, p. 135) made use of it
in his “Synopsis of Genera’, but DUNCKER (Mitt. a. d. naturh.
Mus. Hamburg tgt2 and 1915) made a profound study of
this organ and gave an arrangement of the Synxgnathidae essen-
tially corresponding with the groups higher than genera in
the following:

1) THUNBERG’s article was published as N°. 30 in
the first volume of the Physiograph. Selsk. Hanp-
LINGAR which was edited between 1776 and 1786.
Prof. E. LONNBERG of Stockholm was kind enough
to inform us, that part 4 of the first volume contained
the articles 28—33 and was ready May 1786. It is
therefore probable, that THUNBERG’s article (N°. 30)
appeared already in 1785 or even earlier and that
therefore his name S. ¢etragonus is prior to S, biacu-
featus of Bloch, as one is inclined to suppose in
accordance with the nomenclature and synonymy of
Linné-Gmelin. But this can not be proved as, according
to the kind information of the present secretary of
the Physiographic Society of Lund, the “Protocols”
of the Society contain nothing about the article
of THUNBERG.

D. 29; A. 4; Rings 18-—19 + 32; subdorsal rings 3—4 + 4—5.
Much elongate. Height about 18—1g in total length. Character
of cristae and operculum unknown. Head about 6°/, times in
length. Eye 6—7 times in head. Snout much longer (but less
than twice) than postorbital part of head. Tail, the caudal
included, slightly longer than trunk and head, but less than
twice longer than trunk alone. Colour greenish. Length 139 mm.
Habitat: Java (Batavia, in fresh water).
Note: This species is only known from the description of
BLEEKER, made after an inedited figure of VAN HASSELT. It
has never been found again and is therefore rather dubious;
perhaps it is identical with D. deokhatotdes (Blkr.).
In the Leiden Museum is a specimen (N°. 3852) collected
56
by KUHL and VAN HASSELT in Java, with the label Syngnathus
fluviatilis K. & v. H., written in their time. This specimen,
186 mm. long, is evidently a MMicrophis brachyurus Blkr. and
therefore quite different from the above named species.

female much compressed. The superior cristae only are conspi-
cuous, the remaining cristae rounded, smooth and nearly incon-
spicuous. Head without or with very feeble ridges. Superior

praenuchal and two nuchal shields. Operculum without keel
or with the indication of a keel at its base, but with radial
furrows and lines. Snout short, equal to or shorter than post-
orbital part of head. Tail longer than head and trunk. Dorsal
long, with more than 4o rays, situated above at least 12 rings
belonging for their largest part to the tail; anal before middle
of length. Pectorals present; caudal well developed or small.
Eggs rather large, in isolated cells, formed by the skin of the
abdomen and laterally protected by ventrally converging plates,
which belong. to the lower lateral edges of the trunk, the
posterior ends of which are connected by a fold of the skin.
Distribution: Living in fresh water of brooks and rivers
from East Africa, Madagascar and neighbouring islands through
the indo-australian Archipelago to the Philippines, Japan and
West-Pacific islands.

1) We agree with the opinion of DuNCKER, that the name D. excisus Kaup
ought to be reserved for the species known from the Red Sea. KAup mentions in
his first paper (Arch. f. Naturgesch. XXI. 1, 1853, p. 233) only the Red Sea
as locality. The specimens, which he quotes, belong to the Museum of Berlin
and Paris. Those of the Berlin Museum were collected by Hempricn and
EHRENBERG and belong to D. excisus Kaup emend. DuUNCKER. This is also the
case with the specimens from the Paris Museum, which were afterwards described
by DuMErIL.

The only reai difference seems to be that its snout is still
more slender and conspicuously less than half the length of
the head. -It:iseems-_to be: restricted “to the /Pacific- Islands
whereas C. fasciatus is a more western form. Perhaps DUNCKER
is right when he supposes that C. conspicillatus Jenyns is only
a local variety of C. fasctatus.
2. Corythoichthys crenulatus (M. Web.) |Fig. 30, p. 69].
Syugnathus crenulatus Max Weber, Siboga-Expeditie, Fische. 1913, p. 100.
D. 27—30; P. 14; Rings 15—17 + 35—40; subdorsal rings
I + 5—6.
Extremely slender; trunk nearly four-sided, its height slightly
more than its breadth; all the edges finely serrated, ending
on each ring with a prominent tooth, the fish therefore strongly
adhering. Head 7—8 times in length, more than twice in
length of trunk. Snout. nearly equal to half length of head,
somewhat compressed; its dorsal profile gently rising to the
orbits; its median crest ends in the narrow orbital space,
which is limited on both sides by a sharp supraorbital crest,
which is continued in a curve to the occiput. The occiput
with a sharp crest, which is continued on the nape. All crests
and edges on the head are serrated. Operculum with a rather
high, sharply serrated, complete longitudinal keel. Superior
cristae of trunk are continued nearly to the end of the dorsal
or not so far. Superior cristae of tail reach nearly to the
commencement of the dorsal; the median cristae of the trunk
reach as far. Caudal equal to postorbital part of head. Tail
somewhat more than twice the length of trunk. Colour diffuse
grayish with somewhat light cross-bars on the tail. Snout
vs oom
are
ie
darker with a blackish longitudinal streak or the colour is
light yellow with black points on the snout, a blackish net-
work on the head and faint cross-bars on about each second
ring formed by blackish rings between each pair of edges.
Length 61 mm.
Habitat: Java (Samarang!); Island Binongka!; Timor
(Kupang!).
All the specimens were caught on the surface of the sea.
Note. The above description is based on young specimens
of which the fullgrown form is not yet known. They cannot:
belong to Corythoichthys fasciatus (Gray) as DUNCKER (Mitt.
-a. d. naturh. Mus. Hamburg XXXII. 1915, p. 73) thought
probable. We had the opportunity to compare with the above
described specimens about thirty juvenile specimens of C. fas-
ctatus of the same or somewhat smaller or larger size. They
show the same form of snout, the dorsal profile of which does not
yet rises abruptely, but gently, to the orbital region. This is
therefore indeed a juvenile character, but the young ones of
C. fasciatus do not show the slightest trace of the sharp
serrature of all the edges of head and body and operculum,
which is so characteristic of C. crenulatus. Besides C. crenulatus
seems to be a true pelagic species. At least, all known speci-
mens were caught in surface nets partly with the help of
electric light.

nued as a low crest on the concave, very narrow interorbital
space ; a low somewhat scalloped crest
on occiput and nape. In front of each
nostril a prominence with about four
spines. Orbital borders denticulated ;
from their dorsal middle a curved,
denticulated ridge runs to end of

only anteriorly visible, reaching not farther than
to its middle. Superior cristae of trunk and tail
discontinuous as also the inferior cristae of trunk
and tail. Median cristae of trunk and inferior cristae
of tail continuous. Intermedial shields (scutella) large ;
a praenuchal and a nuchal shield present. Tail
equal to or somewhat more or less than twice the
length of the trunk. Dorsal short with 17—23
rays, its basé not elevated, situated on one or two
of the last body-rings or on none and on 3—5 tail-
rings. Pectorals, anal and caudal present. Eggs
rather large, isolated in cutaneous cells on the
anterior 14 or 15 rings of the tail; they are late-
rally protected by thin cutaneous folds which begin
behind anal and converge posteriorly; they coalesce
temporarely in the median line. These skin-folds
may contain feebly developed bony plates.

Shields with the edges, especially the dorsal ones, serrated.
Median cristae of trunk reach to last ring of trunk and are
subcontinuous with the superior cristae of tail. Head 10 times
in total length. Eyes large, the orbits rise suddenly and are
closely pressed together so that the forehead is very narrow.
Snout short, thick, equal to postorbital part of head, thrice
the diameter of the eye; it carries laterally on its upper profile
irregular rows of small spines. The conspicuous occipito-nuchal
crest divided in three portions and finely denticulated; similar
denticulations round the orbits and on the keel running from
the orbits to the occiput. Operculum roundish, bulging, rough
and divided into two dissimilar parts by a prominent keel.
Tail twice the length of the trunk. Colour brown, with a
yellowish brown crossbar and speckling on each ring. Length
of the single specimen known 80 mm. [Not seen by us].
Habitat: Java (according to KAUP (1853) and to DUMERIL),
whence it came by KUHL & VAN HASSELT in the Museum
at Paris. Evidently by mistake, KAuP states later on (1856),
about the same specimen, that it was found at Wahai on Ceram °).

differences in the slenderness of the body, the length of the snout, the subcon-
tinuity or continuity of the median cristae of trunk and superior cristae of tail,
according to the locality of this widely spread species.

specimens from Java in the Leiden Museum were collected by KUHL & VAN HASSELT
and are named on their label Sywgnathus varicgatus KK. v.H., a name previously
(1811) used by Pallas for specimens of S. acuzs L. from the Black Sea. The other speci-
mens from Java Sea and Pulu Weh were recently collectedby Dr. P. BUITENDIJK,
that from Palabuan ratu, South coast of Java by Major Ouwens. The Amsterdam
Museum contains some specimens of the same species given by VAN DER HuGT
and said to be collected in the Moluccos. They agree in every detail with the
above description, but we are not quite sure about the locality, as we are not
free of the suspicion, that VAN DER HucT collected also on his homeward voyage

generally belong for the largest part to the tail;
caudal short. Eggs isolated in cutaneous cells on

edges increasing in height posteriorly and ending in a sharp tooth. We draw
attention to this fact also on account of the following reasons. In the first place
because DUNCKER erroneously unites /. kampeni M. Web. with JZ. dedcheri Kaup
(see also note on p. 94); in the second place because Kaup (Cat. Lophobr. fish, p. 30)
says, that in the Leiden Museum are specimens of /. ée/cheri Kaup brought
from Borneo by Dr. MULLER. At present that Museum contains of Syngnathidae
brought by S. MULLER from Borneo only Doryichthys spinosus Kaup = Microphis
boaja Blkr. and Syngnathus micrognathus K. & v. H. (Museum name!) = Coe/o-
notus liaspis (Blkr.). We presume that /. dedcheri Kaup is a species not repre-
sented in the indo-australian Archipelago but confined to the shore waters of
continental Asia and Japan.

Halicampus conspicillatus Kp. 1856 on the following grounds: “Kaup zitiert
(l.c.) als Synonyme ‘ Syngnathus conspicillatus Jenyns” und einen von ihm
selbst im Mus. Brit. angewandten Ms.-Namen ‘“/Hadicampus Grayi.” Da er
jedoch in seine Beschreibung von Hadicampus conspicillatus auch JENYNS’ Diag-
nose von Corythoichthys conspicillatus mit einbezieht, betrachte ich BLEEKER’s
Bezeichnung Syxgnathus koilomatodon als erste eindeutige der vorliegenden Art.”
We follow the opinion of DUNCKER,

Note. GUNTHER separated (loc. supra cit.) some specimens
from Ambon and Australia from this species under the name
of B. caudimaculata, on account of their larger eye, longer
head and somewhat longer pectoral fins. Among the numerous
specimens from the Indo-australian Archipelago, examined by
us, we find only one in which the eye goes less than 3 times
in the postorbital part of the head, what would be in accor-
dance with GUNTHER’s &. caudimaculata. But in this specimen
the head and the pectoral fins are not longer than in the
other ones. The length of the pectoral fin seems to be rather
variable, being sometimes shorter, sometimes even longer than
the postorbital part of the head, without being accompanied
by other constant differences. We see therefore no reason to
follow GUNTHER and have included &. caudimaculata Giinther
in the synonymy of 7. strongylurus.

end of the very short description we read: “Arab. Chaerman
vel Choram.”
RUPPELL was the first to use the word choram as a specific
name, and he correctly called the species “Selone Choram
Riippell’. But on the same page he introduced the mistake,
which has been made over and over again by all later authors —
excepting VALENCIENNES — when he said of the species
that it is: “bereits von FORSKaL as -sox Choram angedeutet
worden”.

Note: We have compared our specimens from the indo-
australian Archipelago with an Atlantic specimen from Curagao
and cannot find any difference. This species is rather a variable
one, but this variability is independant from the geographical
distribution. Specimens from the indo-australian Archipelago
for instance show all the differences, which OGILBY (I. c.)
supposes to exist between the atlantic, the east pacific and
the australian specimens.

Species of doubtinl occurrence:
I. Xenentodon cancila H. B.
MACLEAY (Proc. Linn. Soc. New South Wales, VII. 1883,
p- 592) records this species from Port Moresby, New Guinea.
As this species has only been found in freshwater of the
Asiatic continent and its near relative X. canczloides is only
known from Sumatra and Borneo, we agree with OGILBY
(Mem. Queensland Mus. V. 1916, p. 128) when he says: ‘1
am inclined to doubt the correctness of the identification of
this Indo-Burmese fish so far east”’.
It is not improbable that MACLEAY’s specimens belong to-
Lylosurus kreffti, which species lives in the rivers of New
Guinea and has a superficial likeness with . cancz/a.

Very elongate, slender, cylindrical or compressed. Maxil-
laries firmly united to intermaxillaries, which form a flat
horizontal, triangular expansion. The symphysis of the lower
jaw is always prolonged, sometimes only very little so, but
generally much, so that the lower jaw forms a long, slender
beak. Teeth rather small, often tricuspid, the part of the lower
jaw in front of the intermaxillaries generally without teeth.
No teeth on palate or on tongue. Pectorals inserted rather
high up, of moderate length, by exception very long. Dorsal long
or short, far back, beginning before, above or behind origin
of anal. Anal long or short, in the males of viviparous species

Note. Day described (Fishes of India 4°, p. 515) under the
name of //7. Georgi a species, which is not identical with the
one described by CUVIER & VALENCIENNES. Day did evidently
so after examination of what be believed to be the type of
georgu. He says: “DUSSUMIER’s specimen of //. Georgi from
Mahé is stili preserved at Paris; it has D.15” etc. At the
end of the description of 7. georgz in the Histoire Naturelle
des Poissons we read however: “L’ individu que nous venons
de décrire est long de dix pouces et demi. I] vient de la
rade de Bombay. Nous en avons un second exemplaire de
méme taille, péché dans la baie de Mahé, de Coromandel.”
Evidently the french authors made thus a mistake in labelling
this second specimen as georgiz. DAY gives under the syno-
nymy of his species also Hemirhamphus marginatus. This is
however still an other species, differing in the number of
dorsal and anal rays, in the form of the triangular part of
the upper jaw etc.

Note. GUNTHER (Cat. Brit. Mus. VI. 1866, p. 265) described
quite another species from Hongkong as Hemirhamphus mela-
nurus C.V. The description in the “Histoire naturelle des
Poissons’ is too short to state with absolute certainty if
BLEEKER’s or GUNTHER’s A. melanurus is that of C. V. As
C.V.’s specimen came from Celebes and as the description of
the colour agrees exactly with that of BLEEKER’s specimens,
we think that BLEEKER’s species has to be called melanurus C.V.
That of GUNTHER’ has to be called Giintherz, which name
was proposed by BLEEKER (Atl. ichth. VI. p. 59). KNER
(Novara Exp. I. p. 324) mentions melanurus C.V. from Madras,
SEALE (Occas. Papers B. P. Bishop Mus. IV. rgo6, p. 13) from

‘Note. Very young specimens are characterized by having
a row of about 15 partly alternating black points on each side
of the back, between the end of the dorsal and the head
(see MAX WEBER l.c.).
Besides these specimens we have 7 specimens from Pulu
Babi, West Coast of Sumatra, which are less compressed
(breadth 1.1—1.2 in height), have a comparatively somewhat
larger eye and have the origin of ventrals conspicuously
nearer to base of caudal than to head. The triangular part
of the upper jaw is somewhat longer, nearly as long as broad.
In every other point they are like HY. dalinensis.
We propose to call them H/. dalinensis var. occidentalis.

- Note. We have united 4. fasciatus Blkr. with H. margi-
natus Forsk. BLEEKER described this species after one specimen
of 64 mm. One of us described afterwards other specimens
159
of 55—S8o mm. We have now a series of specimens, which
show the transgression from typical 47. fasczatus to H. margt-
natus. In specimens of 35—85 mm. length the body is cross-
barred, in two specimens of 133 and 135 mm. and in another
of 164 mm. there are still a few traces of these bars. The
ventrals are extremely developed in very young stadia. In
specimens of 35—50 mm. the ventrals are even longer than
the pectorals and reach far on anal. In a specimen of 62 mm.
the ventrals, although still reaching on anal, are shorter than
the pectorals. One of the principal features of BLEEKER’s
H. fasciatus is the form of the dorsal, which is not concave,
the first rays being the shortest, the fin is gaining in height
posteriorly. In our specimens from 35—86 mm. this is distinctly
the case, the last dorsal rays reaching on caudal. In a specimen
of 133 mm. these last dorsal rays are still somewhat longer
than the anterior ones, but don’t reach the caudal, while in
a specimen of 162 mm. the first dorsal rays are longer than
the rest. In the young stages (H. fasciatus), the fins, especially
the ventrals, which are nearly black, are much more densely
pigmented than in the adults.

Entire head 2.9, 3.4—3.5 in length with caudal. Length of
lower jaw beyond extremity of upper jaw 7—8 in length,

of head and about equal to the interorbital space, which is
convex. Triangular part of upper jaw, formed by intermaxil-
laries, very short, about thrice as broad as long. Praeorbital
almost quadratic, much shorter than eye. Origin of anal about
opposite to 5th ray of dorsal. Origin of dorsal separated by
about 32 scales from occiput and by 5—6 scales from lateral
line. Dorsal concave, the rays increasing in length posteriorly;
free border of anal straight. Pectorals as long as head from tip
of upper jaw to branchial opening. Ventrals about half as long
as pectorals, the inner ray the longest. Base of ventrals some-
what nearer to base of caudal than to end of pectorals. Caudal

lateral narrow violet band. Tips of ventrals, pectorals, and
posterior part of dorsal and anal black. Length 76 mm.
Habitat: Timor!; between Gebe and Fau!. — Pelagic.
Note. We have three specimens of this species, two of
which have already been described by one of us from material
of the Siboga Expedition, and one from the anchorage of
Kupang, Timor, collected at night by the late Dr. v. D. SANDE.
It is possible that they represent only a young stage of an
unknown species and
that the form of the
dorsal f.i. will change
afterwards, as is the
case in 7, marginatus ;
but the fact that we
did not find such a
form among the very
Fig. 57. Hemiramphus spec. juv. ' :
Head of a young specimen with black dermal extensive material of
appendages on the chin, Hemurhamphus from
the indo-australian Ar-
chipelago at our disposition, makes this supposition improbable.
The great length of the pectoral and the convex interorbital
space distinguish it from all species known to us, even from
their young stages. Perhaps it is nearest to Hemirhamphus
cuspidatus C.V. (Hist. Nat. Poissons XIX. 1846, p. 56), only
imperfectly known from the description of the french authors.
This species has also a long pectoral, short intermaxillaries
and — according to the figure — a convex interorbital space
and a dorsal, the upperborder of which is not concave. It
has however a much shorter lower jaw ('/,, of the total) and
other fin formulae: D. 18, A. 12.
GILL (Proc. Acad. Nat.Sc. Philadelphia, 1863, p. 273) separated
the lastnamed species from /lemirhamphus and created the genus
Oxyporhamphus for it. We think it better for the moment to
keep our species under Hemirhamphus, although it stands
somewhat apart in this genus, as the genus Oxyporhamphus
is still so imperfectly known. The fish described by SEALE
from the Philippines as Oxyporhamphus brevis (Philippine
Journ. of Science IV. 1909, p. 495) is quite different and
belongs to the genus Arrhamphus (see p. 171).
i6t
A small specimen of 51 mm. length, from the Island Binongka
belongs probably also to AH. convexus. It is however disting-
uished by two black dermal appendages of 2.5 mm. length,
situated on a common base on the chin (Fig. 57 after M. WEBER,
Siboga Exp. Fische 1913, p. 133).

“The length of the head from the apex of the intermaxillaries
is '/, of the total measured to the point of the lower, longer,
caudal lobe. The length of the lower jaw, from the apex to
the angle of the mouth, slightly exceeds the length of the
head, varying in different individuals from '/, to '/, of the
distance to the point of the lower caudal lobe. The horizontal
diameter of the eye is '/, of the length of the head; the
distance across the forehead equals 1'/, diameter. The depth
at occiput slightly exceeds !/, of the length of the head, and

the lower caudal lobe. The upper caudal lobe is ?/, of the
lower. The ventrals are placed opposite the posterior third of
the distance between the apex of the intermaxillaries and the
root of the caudal. Head above and back bluish black; lighter,
silvery on the sides above the lateral line; rest of the sides,

Habitat: Singapore (KAROLI). — Pinang, Pondicherry.
Note. Nothing is said about the shape of the triangular
part of the upper jaw, nor of the position of dorsal and anal
fins. It was therefore impossible to give this species a place
in our key.

BLEEKER mentions this fish 3 times (Journ. Ind. Arch. III

Celebes, p. 47) each time from Makassar, but in his later publi-
cations as well as in the ,Atlas ichthyologique” no mention
whatever is made of this species, which is ranged amongst
the doubtful species by GUNTHER and has been — witha
query — very briefly and insufficiently described by KNER
(Fische Novara Exp. 1865—1867, p. 324) from Ceylon. Weare
at a loss which species was meant by BLEEKER. LESUEUR
has described a variety of his erythrorhynchus too (l.c.) and
this variety has been united by CUVIER & VALENCIENNES (Hist.
nat. Poissons XIX. 1846, p. 35) with “7. dussumzerz (not with
HI. gaimardi as the authors themself state by mistake on p. 41).
It is thus possible that BLEEKER meant 7. dussumiert by his
erythrorhynchus.
We have examined, in the Vienna Museum, the specimens
mentioned above and described by KNER as ff. erythror-
hynchus Less.?. They seem to us to belong to 1. xanthopterus C.V.
as described by Day.

Very elongate, body more or less compressed. Mandibles

prolonged into a long beak, which has no teeth, except in
the part opposite to the intermaxillaries. This beak is bordered
by 3 more or less conspicuous folds of the skin, one along
each edge and a median one, beginning on the chin. Inter-
maxillaries forming a triangular plate, which has a band of
teeth, similar to that of the lower jaw. The teeth are small
and conical. Origin of dorsal far backwards, somewhat before
that of anal, which is much shorter than the well developed
dorsal. In males some of the dorsal rays are often prolonged
and some of the anal rays much enlarged. The articulations
of lastnamed have increased in number and are much broadened.
From their posterior side a great number of very fine secun-
dary rays take origin, giving to the whole ray the appearance
of a bird’s feather from which one half of the vexillum has
been removed (see fig. 58c). Pectorals inserted high up, not longer

than the head. Ventrals small, nearer to caudal than to head.
Caudal rounded or more or less truncate, never forked. Scales
moderate, deciduous. The scales on the back overlap each
other in two directions. In the anterior part each scale covers
with its anterior (cranial) border, part of the scale in front of
it, while in the posterior part just the opposite takes place,
and the posterior (caudal) border of the scales covers part of
the scale behind it, as is usually the case. At the point where
these two systems of overlapping meet, there is a central
scale, which overlaps the scale in front as well as that behind
it and remains uncovered itself. Lateral line running low down.
Gillrakers well developed. Third upper pharyngeals ankylosed.
Viviparous.

2. Fam. EXOCOETIDAE.
Elongate, more or less compressed. Maxillaries free from or
merely adherent to intermaxillaries, which do not form a
triangular expansion, but have a straight transverse anterior
margin. The symphysis of the lower jaw is sometimes prolonged
into a small knob, which projects somewhat before the upper
jaw, but generally the jaws are subequal. Teeth rather small
or minute, rarely tricuspid, in the jaws and sometimes on
palatines, by exception also on vomer, pterygoids and tongue.
Pectorals inserted rather high up, very long, forming an organ
of flight and consisting of many rays, the first or the first and
second of which are undivided. Ventrals short, moderate or
long, in the last case assisting the pectorals in suspending the
fish in the air. Dorsal far back, beginning above, or behind
origin of anal; both fins of about equal length or the dorsal
longer than the anal. Caudal deeply forked, the lower lobe
the longer. Scales large or moderate. Lateral line running low
down. Gillopenings wide, gillmembranes not united with isthmus.
Third upper pharyngeals simply coalescent, the plate readily
separating into its two components.

Note. We have examined specimens of £. oligolepis, bra-
chysoma and neglectus of BLEEKER’s collection in the Leiden
Museum. We can’t find any difference between specimens of
the two first named species, while the specimen of F£. neglectus
is a little more elongate and has 28 rows of scales between
occiput and dorsal, while the others have only 22 or 23. One
of us [I.s.c.] has already mentioned a specimen from Obi, which
has the measurements of drachysoma but the high number of
scales between occiput and dorsal of neglectus. The differences
between £. negléctus and the other two species are thus bridged
over. There is no difference in the number of dorsal rays
between the three species of BLEEKER, as mentioned by
the author.

Note. This species is allied to C. dahzensis and C. oligolepis,
from both of which it differs through the absence of teeth
on the palate. It is moreover distinguished from C. éahiensis
by its greater height, smaller teeth, less blunt profile of snout,
and from C. olzgolepis by its simple, not tricuspid teeth and
smaller scales.

Note. LUTKEN l.s.c. examined specimens from Java, from
which the author says, that they did differ in details from
Exocoetus brachycephalus Gthr. It is possible that these speci-
mens, the only ones recorded with certainty from the indo-
australian Archipelago, belonged to the allied C. g7/bert2 Snyder
(Bull. U.S. Fish Comm: XX. 1904, pis 22).
We examined a specimen of C. rondeleti (C.V.) in the collec-
tion of the Zoological Museum of Amsterdam, without locality,
but probably from the indo-australian Archipelago.

Note. The brief description given by BLEEKER of his
Polynemus diagrammicus gives no clue as to the exact position
of this species. It is possibly identical with P. pfecfferz, the
differences given by BLEEKER in his description of lastnamed
species being easily explained by differences of age. The last
mention made by BLEEKER of P. diagrammicus is in his
“Enumeratio piscium’”’ etc. (Act. Soc. Sc. Indo-Neerl. VI. 1859,
p- 39). This makes us suppose, that the specimens were lost.
They are neither in the British, nor in the Leiden Museum.
In these circumstance we think it safest to place P. dia-
grammicus as a doubtful synonym of P. pfezfferz.

Origin of first dorsal almost above that of ventrals. First spine
of first dorsal minute, hidden below the scales. Third spine
longest, not weaker than second one and about as long as
head. Spine of second dorsal somewhat longer or shorter than

Doubtiul species:
VON MARTENS mentions (Arch. f. Naturgesch. 34. Jahrg.
Bd. I. 1868, p. 13) Polynemus paradiseus L., a species from
the Indian Ocean, with the name of-the species between brackets
and with a query from Borneo. It is probable, that VON
MARTENS’ specimen belongs to a related species, as P. para-
diseus has never been found in the indo-australian Archipelago,
although DUNCKER (Mitth. Naturh. Mus. XXI. 1904, p. 155)
mentions it from the Malay Peninsula (fishmarket of Klang).
2. Fam. SPHYRAENIDAE.
Body much elongate, subcylindrical, covered with small
cycloid scales. Lateral line well developed, straight. Head very
long, with prolonged snout, scaly on top and on sides. Cleft
219
of mouth horizontal, wide, bordered by the intermaxillaries
which are not protractile, behind which are situated the broad
maxillaries, with a supplemental bone. Lower jaw considerably
projecting. Teeth large, unequal, fang-like, implanted in sockets,
in both jaws and on palatines, none on vomer. First dorsal
with 5 strong spines above ventrals, which are before middle
of body. Second dorsal far behind first, similar to anal and
opposite to it. Caudal forked. Pectorals short, placed rather low.
Pelvic bones not connected with the pectoral arch. Third and
fourth superior pharyngeals separate as also lower pharyngeals.
Gillopenings wide. Gillmembranes not united, free from isthmus.
Branchiostegals seven. Gillrakers very short or obsolete. Verte-
brae 24.
Carnivorous, very rapacious and active pike-like fishes, often
of large size and therefore dreaded by fishermen, living in
tropical and subtropical seas, often near mouth of rivers.
By sailors known as Barracuda.

3. Fam. MUGILIDAE.
Oblong, cylindrical anteriorly, more or less compressed poste-
_tiorly. Head usually broad and flattened. Head and body
covered with rather large cycloid or ciliated scales. No lateral
line, but lateral scales eften with a pit or streak, Eyes mode-

rate or large, lateral. Mouth terminal or subinferior, usually
transverse, laterally not extended, or longitudinally cleft and
reaching even to below eye. Jaws equal or the lower included ;
intermaxillaries protractile. Maxillaries, which are often hidden
in a groove between intermaxillary and praeorbital, have no
supplemental bone. Teeth absent, or minute dermal, ciliiform
ones on lips, or true small teeth at least in upper jaw. First
dorsal with four stiff spines, second dorsal well separated from
first, longer than it and similar to anal, which has three weak
spines. Ventral fins abdominal, more or less approximated to
pectorals, which are situated in or above middle of height.
Pelvic bones not attached to cleithra, but firmly connected
with postclavicles. Caudal emarginate. Fins, except first dorsal,
usually more or less covered by scales. Third and fourth supe-
rior pharyngeals at each side anchylosed, not bearing teeth,
forming a complicated structure, which narrows the oesophageal
opening. Lower pharyngeals separate. Gillopenings wide. Gill-
membranes separate, free from isthmus. Branchiostegals 5 or 6.
Gillrakers long and slender, forming a filtering apparatus.
Vertebrae 24—206.
Fishes of moderate size, living along the coasts and in
estuaries and freshwater of tropic and temperate regions.
Feeding on organic matter contained in mud and sand, which
is filtered by the gillrakers and swallowed, while larger and
indigestable parts are dejected.

1. Mugil Linne.
(LINNE, Syst. nat. edit. Xa. 1758, p. 316).
Body oblong, more or less compressed, sometimes anteriorly
depressed." Head rather large, convex or depressed, scaly
above and on sides. Cleft of mouth more or less transverse,
its lateral extension short and ending far distant from orbit.
Mouth usually subinferior, formed by intermaxillaries, the maxil-
laries being small, only their end visible or concealed by the
well developed praeorbitals. Mandibles with a sharp margin.
Upperlip fleshy or narrow, with or without papillae. Lips some-

times ciliated by minute, flexible dermal teeth; no teeth on
palate. Eye large, with or without an anterior and posterior
gelatinous eyelid, covering part of the iris.
For other characters see those of the family.
The numerous species are living in shoals in sea along the
shores, in brackish estuaries entering freshwater of rivers, oc-
curing in all tropical and temperate regions, forming a common
food-fish of considerable importance. Some species have a very
wide, Mugil cephalus L. even a nearly world-wide distribution.
Remark: We use as primary distinguishing characters the
number of scales counted in a lateral line from gillopening to
the small scales on root of caudal; the position of the median
fins opposite to these scales; the number of the soft rays of
the anal; the length of the pectorals and their extension along
the “lateral line’; the development of a gelatinous eyelid;
the character of the upperlip and if the maxillaries are visible
or not. Discrepancies between our statement about the number
of lateral scales and those of BLEEKER are explained by the
fact, that BLEEKER also counted the small scales on base
of caudal.

Note. BLEEKER mentions this species under the name of
Mugil cephalotus C.V. from Java (Samarang, Surabaya, Besuki,
Batavia) and Madura, but only in lists of fishes published in
1845, 1849 and 1850. We are not sure, that these determina-
tions were correct, as in later lists this species is mentioned
only from Madagascar and China, but not more from the Ar-
chipelago. We can’t make out if KNER (l.s.c.) really disposed
of specimens of this species from Java or if he mentions it
from Java in his article on the authority of BLEEKER.
It is an extraordinary fact, that JZ. cephalus L., known from
so many localities in tropical and temperate seas all over the
world, is very rare in the Archipelago and with any certainty
only represented in New Guinea and Borneo. Lastnamed loca-
lity is based on a specimen examined by us and preserved
in the Leiden Museum under N°. 1671. On the label is written

with caudal'). Eye 3 or more in length of head, nearly 1'/, in
its postorbital part; no gelatinous membrane. Interorbital space
only slightly convex, nearly as broad as half length of head.
Snout slightly convex, shorter than eye. Praeorbital somewhat
emarginate, squamate, only its posterior border finely denti-
culate. Maxillary invisible or nearly so when mouth is closed.
Upper lip very thick, high, forming frontborder of snout, infe-
riorly with an indistinct series of obtuse low papillae which
may be wanting’); lower lips not papillate, emarginate at
symphysis. Symphysial knob double. Origin of first dorsal
separated from snout by 20 praedorsal scales, about midway
between end of snout and base of caudal or somewhat nearer
to caudal, opposite to 12th—1 3th Jateral scale. Dorsal spines rather
weak, longer than postorbital part of head, but lower than
second dorsal and anal, which are concave and scaly. Origin
of second dorsal opposite to 24th—25th lateral scale and somewhat
behind origin of anal. Caudal emarginate, its base scaly. Pec-
torals equal to or somewhat longer (in small specimens shorter)
than head, not reaching origin of first dorsal; an axillary
scale on pectorals is wanting or small, but present on axil of
ventrals and at base of first dorsal. Least height of caudal
peduncle less than 1'/, times in its length, nearly twice the
length of head. Silvery, olivaceous above, generally a dark
spot superiorly at base of pectorals. Fins yellowish. Length
228 mm.
1) The valuation of height and head is taken from BLEEKER’s description as
we dispose of small specimens only, less than 100 mm.
2) Their presence depends perhaps on sex or on season of rut.

Of this australian and pacific genus
Myxus cf. elongatus Gthr.
is quoted by E. VON MARTENS (Preuss. Exp. Ost-Asien, 1876,
p. 310) from Singapore.
We suppose that this is erroneus, though it may be possible,
that Myxus elongatus Gthr. may be found in New Guinea or
the Aru Islands.

She has been so kind to give us also valuable information about the specimens
of BLEEKER in the Leiden Museum. The seven examples are contained in two
bottles. By examining them one example of 220 mm. length showed the characters
of C. goldiei, as remarked on page 263.

A. III, 8; scales 26—2g in horizontal series, the specimens being a ayy,
in such condition that it is practically impossible to make an cia
accurate count. Teeth in a villiform patch in each jaw, the
outer row considerably enlarged. The teeth in the inner rows
are so small that they can not be detected by the use of a
dissecting needle but are plainly visible under the microscope.
Looking directly down on their ends they look like minute
papillae. Papillae of similar appearance are visible in all parts
of the roof of the mouth of the cotype, being especially crowded
on the head of the vomer. The teeth of the outer row are
strong, conical abruptly recurved and, perhaps, slightly flattened
at the tip. In Agonostomus monticola the teeth in the jaws are
all recurved, with the tip flattened, spoon-shaped, bicuspid or
tricuspid. A careful inspection will show all types in the same jaw.
“Mouth very small, oblique, the lower jaw strongly pro--
jecting. The maxillary does not reach front of eye.
“Caudal rounded; soft dorsal opposite anal and similar to
it but with slightly shorter base.
“Scales ctenoid, a single row of teeth on the edge of each.
In Agonostomus monticola there are from three to six rows of
fine teeth on the outer edge of each scale. An unidentified
specimen of ¥oturus has the entire exposed surface of the
scale closely covered with fairly strong teeth.
“This species differs from all other species of Agonostomus
of which we can find any description in the small number of
266
scales. The mouth, also, is smaller and directed more upward
than in others. The teeth are apparently larger than A. monticola.
“Color in alcohol uniform pale brownish.
“The dorsal fins were apparently black in life.’” UA
In their last sentence the authors themself draw already
the attention on the characters in which this species, of which
they give a figure, differs from all other species of Agonostoma.
We doubt the correctness, that it is an Agonostoma, as in
that genus, at least in the indo-pacific species, the upper lip
is thick, the mandible covered with a thick, callous, trenchant
lower lip, the mouth is nearly horizontal, the lower jaw is
never projecting but more or less included. The ventrals
are more abdominal than in the figure; the pectorals falci-
form, inserted much higher; the caudal emarginate. We even
doubt that the described species belongs to the Mugzlidae
at all, as the first dorsal has five spines instead of four, as
in all Mugilidae; as the ventrals have, according to the figure,
one spine and 4 rays, while in all M/ugzlzdae the ventrals have
J. 5. Further on account of the character of the caudal peduncle,
of the pectorals and their base, of the construction of the
operculum, which are different from those of the Mugzlidae.
We suppose that some mistake must have taken place. The
figure has a superficial likeness with Carasszops.

1) We have changed the original specific name e2drachtensis in een drach-
fensis, as it is derived from the old dutch name “het land Eendracht” for Australia;
endrachtensis does not belong to any language.
2) The type of this species is lost and the diagnosis very incomplete, but it
contains characters, which make it possible, that it was based on a specimen or
specimens of 4. eendrachtensis (Q.G. (see M. Weber, Revision etc. I. s.c. p. 46).

Compressed, height about 5 to 5.5 times in total length.
Head and anterior part of back stout, flattened, broad, its
breadth above pectorals about ?/,, shorter than height on that
place. Head 4.2 to 4.5 in total length, 3.2 to 3.7 times in
length without caudal; its upper surface broad, flat, even slightly
concave, rectilinear to broad, blunt snout, which is shorter
than half length of eye; mouth small, upper jaw somewhat
prominent, maxillary obliquely ascending, nearly reaching verti-
cal through frontborder of pupil. Eye about 2.3 to 2.5 in head,
equal to interorbital space but longer than postorbital part
of head. Origin of first dorsal opposite to 12th, usually 13th
scale, in small specimens midway between root of caudal and
anterior part of pupil. With increasing length the anterior end
of that measurement is shifted backward to hindborder of eye,
so that finally the origin of the first dorsal is midway between
hindborder of eye and root of caudal’). The vertical through
that origin is much nearer to anal than to base of ventrals.
Origin of second dorsal opposite to 20th scale and to anterior
third of anal. Anus opposite to gth, usually 1oth scale, 3 scales

1) The authors unite under this species a number of specimens from Fiji,
Caroline and Marshall Islands. Of some of them a few characteristics are notified ;
these specimens certainly do not belong to evdrachtensis Q.G. but possibly to
A, temminchi Blkr. But the descriptions are too incomplete to settle this question.

1.8 times in length of head. Both fins are separated by §
(by exception 6) interdorsal scales. There are 16 scales between
first dorsal and occiput. Distance of origin of second dorsal
from dorsal root of caudal shorter than head. Pectorals falcate,
4.5 to 4.8 in total length; their tip reaching gth to 12th, usually
‘roth scale. Caudal peduncle, measured behind dorsal, about
equal to half length of head. Scales entire, in old specimens
somewhat crenulated. About 23 gillrakers on lower limb of
first arch, the longest about '/, the length of the eye. Teeth
in jaws in a rather broad band, its breadth increasing with
age, they are relatively strong on vomer, palatines and ptery-
goids. Silvery lateral band usually rather narrow and dorsally
bordered with black, which may be as broad as the silvery
band below it. In the middle of the lateral band a longitudinal
series of diffuse dark brown dots, one on each succeeding
scale; a second series in the ventral border of the silvery
band or somewhat below it and reaching lower surface of
caudal peduncle; a third series, still shorter, about one scale
below the second series. Scales above the lateral band dusky
and more or less edged with dark brown, more pronounced
on median and anterior part of back and on upper surface
of head; tip of snout and of mandible dusky. Base of pectorals
and their upper half dusky as also the other fins, especially
the caudal. Length 116 mm.

Note. This species is widely distributed through the Ar-
chipelago. It was therefore remarkable that BLEEKER had not
received it from one of the many places wherefrom he got
collections. Apparently he did not recognise it; for the Museum
of Amsterdam possesses two badly preserved specimens from
BLEEKER’s collection named by him Azh. duodecimalis C. V.
which really belong to Ach. eendrachtensis.

Note. One of us draw already attention to the fact, that
the specimens called dontz by the inhabitants at lake Towuti,
differ by having less anal rays from typical 7. celebensis. We
find some other differences (lateral line, length of pectorals)
which seem us sufficient to describe them here as a separate
species.

Note. The indo-australian genera and species of Melano-
taeniinae are also treated by JORDAN & Husss (A mono-
graph. review of the family of Atherinzdae, Stanford University
Publications 191g). As the authors had not the benefit to see
the species themself, their treatement of them is a replica of
that of C. T. REGAN. His descriptions are quoted under the
genera and species named on the following pages. We there-
fore did not think it necessary to quote also the identical
names used again by JORDAN & HUBBS.

Note. TATE REGAN, who examined a specimen of this
species, united it with JZ. nzgrans Rich. As however REGAN
unites a number of species under this name, which according
to us have the value of separate species, we don't know where
to place it, as PERUGIA’S description is too short. If there
were really only 28 scales in the L.l., the species would easily
be distinguishable, but we suppose this is a misprint, as other-
wise REGAN would not have united it with J. nigrans, for
which he gives: L.l. 33—37.

“Length of head 4'/,, of caudal fin 5, height of body 3?/,
in the total a Eyes large, their diameter -2°/, in the length
of the head, */, of a diameter from the end of the snout, and
one diameter apart. Upper jaw slightly overhanging the lower;
maxilla does not reach to the front margin of the eye. Profile
in front of the first dorsal straight, or if anything slightly
convex. Both jaws entirely covered with closely set short sharp
recurved teeth; a similar patch on the head of the vomer.
The rays of the second dorsal are equal in height to those
of the first which are not filamentous: the anal commences
behind the origin of the first dorsal fin. Ventrals inserted far
behind the base of the pectorals: caudal forked. Scales with
crenulated edges, covering the cheeks, opercles and upper part
of the head to the middle of the interorbital space; the ante-
rior occipital scales large and prominent; there are 15 scales
in front of the first dorsal fin. Colors, silvery, with nine broad
red longitudinal bands: the dorsals and anal dusky washed
with red, the second dorsal having a basal row of brilliant
crimson spots. The specimen measures + 69 mm.” [After

Note. It is impossible to give this species even its correct
generic position after the short description of the authors. As
OGILBY, one of the authors, placed the species later on (vide
syn.) in the genus Rhombatractus, we don’t know why TATE
REGAN united it with JZ. dumasi under the name of Azzso-
centrus rubrostriatus. He did not see typical specimens and
based his description on two co-types of JZ. dumasz and on
5 specimens from the Setakwa-River. Moreover he gives as —
habitat: Aru-Islands; we don’t know on whose authority. Later
on (Proc. Zool. Soc. 1914, p. 339) TATE REGAN got informa-
tions about the type of the species from McC CULLOCH and
writes: “the type of VV. rubrostriatus Rams. & Ogilb. is damaged
about the mouthparts; a figure of the upper jaw is sufficient
to indicate that examples Lhave recently described as belonging
to this species, are correctly determined.” As the origin of the
dorsal is situated above or somewhat behind that of anal in
M. dumasi, whereas it is — according to the authors — be-
fore that of anal in WV. rubrostriatus, we think it safer to keep
them apart, till lastnamed species is better known.

Distribution: Freshwater of New Guinea, Waigeu and
Aru Islands.
Note: The genus Rhombosoma Tate Regan (Trans. Zool.
Soc. London XX. prt 6, 1914, p. 283) is synonymous with
Rhombatractus as described by M. WEBER (Nova Guinea V.
Livr. 2, 1908, p. 233). REGAN substituted the new name on
the following reasons: GILL created the name Ahombatractus
to replace CASTELNAU’s name Arzsteuws, which was preoccupied.
The species described by CASTELNAU, and which is the type
of Arzsteus Castelnau, is Aristeus fitzroyensis. According to
REGAN A. fitzroyensis is a Melanotaenia; Rhombatractus is there-
fore synonymous with MWelanotaenta, which name is the older.
DOUGLAS OGILBY (Proc. Linn. Soc. N.S. Wales 1896, p. 125)
is of the same opinion. GILL however (Amer. Naturalist 1894,
p- 709), in creating the name Rhombatractus, does not mention
a type, but says that it is a substitute for the group called
Aristeus by CASTELNAU. The diagnosis of Rhombatractus: “Mela-
notaeniines with a much compressed rhombofusiform body,
emarginate dorsal-rostral contour, and no distinct lateral band”
is appliable as well to older specimens of JZelanotaenia as of
Rhombatractus. There is therefore in our diagnosis, giving above,
nothing against the use of the genus name ARhombatractus in
the sense of M. WEBER for those species, which later are
called Rhombosoma by REGAN.

Physoclistic. Cylindrical and elongate or compressed and
oblong. Mouth large or small. Intermaxillaries protractile, exclud-
ing the edentulous maxillaries from the oral border. The jaws
with fixed, conical teeth; in one case (//e/ostoma) only movable
ones on lips. Vomer and palatines with or without teeth. Teeth
on parasphenoid present. Scales large or moderate, cycloid or
ctenoid. Lateral line present and continuous, or interrupted,
or vestigial, or absent. The single dorsal fin long, inserted above
base of pectorals, longer than anal fin, or shorter than it and
beginning behind base of pectorals. Dorsal and anal with or
without spines, the rays branched or not. Pectorals situated
below middle of height. Ventrals thoracic, subabdominal or
absent, composed of six rays, the outer of which is unbranched
or spine-like; the rays may be reduced to one. Pelvic bones
remote from cleithra or attached to them. Parietal bones are
separated by the supraoccipital, an orbitosphenoid wanting.
Four gills. Pseudobranchiae none or rudimentary. A supra-
branchial organ constituted by a system of labyrinthic lamellar
processes from the outside of the epibranchial of the first
branchial arch, enclosed in an accessory cavity, separate from
the pharyngeal cavity, but in communication with the branchial
cavity, by an opening above the two anterior gillslits. In
Ophiocephalidae the suprabranchial cavity is more like a diver-
ticulum of the pharyngeal cavity, as it is in open communi-
cation with it. It is also without a labyrinthiform organ but
covered by a mucous membran fit for accessory respiration.

on upper surface of head. Lateral line present, with a more
or less developed curve in its anterior half or interrupted. Air-
bladder present, continued into a prolongation of the abdominal
cavity in the tail. Anterior ribs sessile, the remainder inserted

1) According. to ‘BEAN &- WEED (Proc. U.S. Nat. Mus. 42, 1912, p. 607),
this species is also found on Java (Buitenzorg, Palabuan Ratu). We suppose
that some mistake is made, as it is hardly believable that BLEEKER and so many
other ichthyologist after him, who collected at Buitenzorg, would have over-
looked this species.

hindborder of praeoperculum. Greenish or brownish above to
almost black, white or silvery or light brown below. Upper
parts with dark streaks and blotches, more or less arranged
in oblique bars running forwards, lower parts with similar
blotches and streaks, at right angles with those of the upper
parts. In older specimens the upper parts are generally so
dark as to make these markings obsolete. Lower surface of
head and belly white, more or less freckled with brown. A
dark band running from corner of mouth to suboperculum,
sometimes very faint or absent in old specimens. Pectorals
brownish to dark brown. Ventrals white, generally freckled
with brown. Dorsal and anal generally freckled or streaked
with brown and white. In young individuals there is sometimes
a black ocellus at the end of the dorsal fin. Caudal brownish,
with obsolete dark bands. Length over 900 mm.

pines, Pinang, Malay Peninsula, Siam, China, British India and

Note: Numerous specimens of this very common food fish
seen by us. According to SUNDARA RAJ (l.c. p. 271): “the nest
consists of a circular clearing in grassy swamps or in the
weedy edges of ponds and rivers. Both parents, the male in
319
particular, keep guard. The eggs, which are large (1.25 mm.)
and float at the surface, are never numerous but vary from
a few hundreds to a few thousands according to the size of
the fish. Dr. A. WILLEY gives a full description of the nest,
egg and young of this species in Spolia Zeylanica, vol. VI,
pp. 108—123.”
Ophiocephalus cyanospilus is known from the type specimen
only, when we except 2 specimens mentioned by VOLZ (Revue
Suisse de Zoologie XII. 1904, p. 460) with a? behind that name.
This type specimen is a young fish of 102 mm. and differs
according to BLEEKER, from O. sérzatus by the presence of
small bluish or mother-of-pearl coloured ocelli on the ventral
side of the trunk. The origin of the dorsal is situated “circiter”
above that of the pectorals and the maxillary reaches only
to below hindborder of eye. Lastnamed character is due to
the young age of the specimen, the other differences from
O. striatus are so slight, that it seems to us justified to range
O. cyanospilus — although with a? — under the synonyms
of O. striatus.
The type of O. cyanospilus, which came from Telokbetong,
Sumatra, is apparently lost, as it is neither in the Leiden nor
in the British Museum.

length with caudal. Head depressed, its upper profile straight,
interorbital space flat. Eye 5.7 (in specimen of 168 mm.) — 7
(in spec. of 285 mm.), about twice or a little less, in small
420
specimens, in interorbital space. Snout less than twice diameter
of eye, its tip in the horizontal through lower half of eye. Cleft.
of mouth rather oblique. Maxillary reaching far behind eye
or to hindborder of eye in small specimens. Lower jaw slightly
prominent. A rather broad villiform band of teeth in the inter-
maxillaries, teeth coarser in the symphysial part, especially
the hindermost. In the lower jaw several rows of teeth near
the symphysis, laterally only one row, behind which equi-
distant strong canines. A A-formed patch of moderate strong
teeth on vomer and an elongate band of strong teeth on the
palatines, the innermost row the largest and caninoid. All the
teeth curved backwards. There are 5 or 6 scales in a row
between the eye and the hindborder of the praeoperculum
and 3-—4 rows on the operculum. Lateral line with an abrupt
curve downwards of 3 scales at about the 14th or 15th perfo-
rated scale. Dorsal beginning behind base of pectorals and
ending somewhat behind end of anal. Its origin separated by
15—16 scales from tip of snout. Origin of anal below 14th
dorsal ray. Pectorals about as long as postorbital part of head.
Ventrals originating about below origin of dorsal, about equal
to distance between hindborder of eye and hindborder of
praeoperculum. Colour of alcohol specimens dark greenish or
bluish above, yellowish or reddish brown below. A rather in-
conspicuous dark oblique stripe behind corner of mouth. Under-
parts of head sometimes with yellow spots. Pectorals and dorsal
and caudal dark, ventrals of the colour of the lower parts,
sometimes striped in their hinderpart. Anal light, with a sub-
terminal dark band. In young specimens (always?) a red lateral
band from snout to caudal. Length 285 mm. [Type of O. dara-
mensts Steind. in the Vienna Museum seen by us].

N ote. Ophiocephalus rhodotaenza is based on a single specimen
of 59 mm. long. A second one, still smaller (41 mm.) has
been recorded by STEINDACHNER. The differences from O. me/a-
nosoma (the presence of a lateral red band and the maxillaries
reaching only below hinderpart of eye) are referable to the
young age of the specimens. We unite O. rhodotaenia there-
fore with O. melanosoma. |

In rivers,
1) O. spiritalis Fowler, from Padang, is intermediate in many respects between
O. pleurophthalmus and O. ducius. The number of scales in the Ll. (55), the
fin formula (D. 29, A. 28) do not give any definite clue to which of the two
species O. spiritalis belongs, although the low number of scales points to O. pleu-
rophthalmus, According to the figure the profile of the head issomewhat concave,
but not so much as in O, decius. The blotches on opercle and body correspond
fairly well with the ocelli of O. pleurophthalmus, but they miss the light rings
of the latter. The bars on the pectorals are again exactly what we see in speci-
mens of OQ. /ucius. O. spiritalis may be a hybrid of the two species, although we
are not aware that hybridisation is known in Ophiocephalus.

considerably shorter than postorbital part of head. Ventrals
not much shorter than pectorals, originating behind origin of
dorsal. Colour variable. In young specimens brownish above,
yellowish below, with a black lateral interrupted band running
from the hindborder of the eye to base of caudal and forming
327
a series of large spots along the side of the body. In the
interspaces between those spots there is more dorsally a
similar row of less dark spots, these two alternating rows of
spots covering almost the whole sides of the body and leaving
a light zic-zac lateral line between them. The centre of each
spot of the upper row is formed by a darker oblique streak,
which is at right angles with similar streaks on the ventral
half of the body. In older specimens the whole fish is much
darker and the markings on the body are more or less obso-
lete, the oblique streaks on the belly, which is lighter, remaining
more conspicuous, but often completely vanishing in old
specimens. Sometimes there are round black spots, irregularly
arranged, on upper part of head and body. Dorsal, anal and
caudal spotted or streaked with rows of blackish or whitish
spots. Similar spots are often conspicuous on the ventral
side of the head. Pectorals white, barred with brown; ventrals
freckled or indistinctly barred with brown. Length 360 mm.

Note. Ophiocephalus polylepis Blkr. is based on a single
young specimen of I14 mm., now preserved in the Leiden
Museum and in such a bad state, that it is impossible to des-
cribe it properly. According to BLEEKER’s description, the
only difference of importance between O. folylepis and luctus
would be that lastnamed species has one row of scales more
above the lateral line than O. poly/epis. In his diagnosis however
BLEEKER states of the scales in the l.tr. “quarum 4 vel 5?
supra lineam lateralem.” All the specimens afterwards labelled
by different authors as O. polylepis and which we examined,
turned out to be O. ductus. We have not seen the specimens
328
of O. polylepis mentioned by VOLZ (Revue Suisse Zool. XII.
1904, p. 460) which is a pity, as VOLZ records O. luctus on
the same page, from the same locality. Probably the last ones
are large specimens, with concave profile, which differ consi-
derably in aspect from the young ones, which he therefore
referred to O. polylepis.

Cylindrical, compressed posteriorly. Height 5.1—5.5, 6.1—6.7
in length with caudal. Head 2.6—2.8, 3.1—3.4 in length with
caudal. Head depressed, rather pointed, flat above, the profile
from occiput to snout sloping in a straight line. Eye 6'/,—7'),,
twice to 2.5 in the interorbital space and about 4.5 in the
postorbital part of the head. Snout longer than, but not twice
as long as eye, its tip in the horizontal through middle of
eye. Cleft of mouth oblique. Maxillary reaching to behind eye.
Lower jaw somewhat prominent. In the upper jaw a pluri-
serial band of small teeth. On the palatines and the anterior
part of the vomer a continuous row of small teeth and imme-
diately behind this a row of distant strong canines. Small
teeth in several rows near the symphysis in the lower jaw,
329
laterally in one or two rows. Immediately behind these a row
of distant strong canines. There are 15—17 rows of scales
between the eye and the hindborder of the praeoperculum
and about 8 rows on the operculum. Lateral line without abrupt
curve, but sloping down in a more or less regular way in
the fore part of its course. Dorsal beginning above or even
somewhat before base of pectorals and ending scarcely behind
end of anal; its origin separated by about 28 scales from snout.
None of those scales on the head very much larger than the
others. Origin of anal below 16th—r18th dorsal ray. Pectorals
about 1.5 or somewhat more in postorbital part of head. Ven-
trals originating at some distance behind pectorals and only
a little shorter than lastnamed fins. Dark brown or bluish
above, whitish below; two black parallel longitudinal bands,
the upper one running from point of snout through eye to

end of caudal, the lower one beginning somewhat above corner
of mouth, running through base of pectoral and also continued
to end of caudal, the interspace between these bands brick-red
in living specimens, but generally faded in preserved ones.
In older specimens the black bands break up into irregular
blotches and quite disappear in old specimens. Dorsal fin dusky
or with irregular longitudinal bands in older specimens. Caudal
dusky, with exception of the two dark bands and the red
interspace in younger specimens. Pectorals, ventrals and anal
whitish, the lastnamed fin with a black longitudinal band in
old specimens. Length 640 mm.

Dion bitfuls peeves:
Ophiocephalus punctatus Bl. a species from British India, but
not known from Siam or Malakka, has been recorded by
KNER from Java (Fische Novara Exp. I. 1865—1867, p. 233).
BLEEKER (Verh. Akad. Amsterdam XIX 1879, Poissons pharyng.
labyr. p. 36) supposes, that the locality “Java” is erroneous.
We agree with BLEEKER, as KNER often made mistakes in
the records of localities. KAROLI (Termesz. Fiizetek V. 1882,
p- 25) records O. punctatus besides from Ceylon, from Borneo
(Matang, Sarawak), Java (Palabuan, Sindanglaja) and under the
name of O. affinis Gthr., which is according to DAY asynonym
of O. punctatus, also from Singapore. Already the fact, that
KAROLI mentions this species from so many localities in the
Indo-australian Archipelago, whereas it has never been recorded
by other authors from there, makes it probable that KAROLI
made a mistake.
We don’t think that O. punctatus ought to have a place on
the list of Indo-australian species.

Note. Although we examined a great many specimens, we
are still in doubt if they all belong to one species or that
more species must be recognized. As the result of our study
we can state, that among the specimens trom the western part
of the Archipelago there occur more individuals with seventeen
dorsal spines and less than 28 scales in the lateral line than
amongst those of the eastern part. We did not find any speci-
mens from the indo-australian Archipelago with sixteen dorsal
spines. BLEEKER however records sixteen spines in A. ol/zgolepis
from Borneo. In three specimens from British India (Calcutta
and Orissa) we find XVI, XVI, XVII, but according to DAY l.c.
the number of spines is XVII—XVIII, so it may be that our
three specimens from British India have incidentally less spines.
DAy seems never to have met specimens with nineteen spines,
but these are rather frequent in the indo-australian Archi-
pelago, especially in material from Celebes and Rotti.
Resuming we may say, that the relative number of speci-
337
mens with more dorsal spines and more scales in the L. 1.
increases from West to East.
Since the times of DALDORFF (1797) this fish, living
in ponds and ditches, is renowned as the ‘Climbing Perch”,
according to its supposed ability to ascend trees, the highly
mobile suboperculum with its strong spines being the chief
organ of climbing. This may happen accidentally, as the fish
is able to leave the water and migrate long distance on land
in search of other ponds, offering better biological conditions.
The progress on land by erecting its fins, scales and oper-
cles lying flat on one side or by keeping its erect position, is
described by Day (Fishes of Malabar, p. 133). The extra-
ordinary air-breathing power by retaining water in the super-
branchial organ, to keep its thin laminae wet, and its creat
tenacity of life enable Anadbas to live even for six days out
of the water or to be buried in exsiccated mud and to bear
transport well, even when exposed for some time to the sun.
Its development is recorded by B. SUNDARA Raj (Records
Indian Mus. XII. I916, p. 276).

An excellent foodfish introduced and naturalized in various
345
tropical countries. Able to live in rivers and ponds, even in
somewhat brackish water, but thriving best in shallow, weedy
ponds; rising to the surface to respire air. When breeding,
the fish takes care of its young. The eggs are attached to
water plants or received in a nest, composed of plants. The
gourami is essentially a vegetable feeder, but he feeds also
on insects, fish and decomposed matter.

Note: There is much uncertainty about the occurrence
of this species in the Archipelago. It was for the first time
recorded from there by one of us, who acquired 8 specimens,
together with Osphromenus goramy and Trichopodus trichopterus
in West Java or more probably in the Highlands of Padang,
Sumatra. Unfortunately this was the only batch of fishes of
the extensive collection, made there, of which the label was
lost (see M. WEBER l.s.c. p. 418). MWacropodus opercularis has
since then (1888) never been rediscovered, neither in Sumatra,
nor in Java, nor elswhere in the Archipelago. We doubt there-
fore more than ever its occurrence in a free state in the
348
Archipelago. Possibly the specimens collected in 1888, most
probably in Sumatra, were introduced as this species is kept
in captivity f.i. in Singapore.

its correctness, as he found the fin-formulé D. VII. 7; A. XI. 18,
thus quite different from the anal of Cv. nodz/zis, though the
total number of spines and rays is about equal. An other
difference in his description aré "une dizaine de raies trans-

_ Note. The species of this genus are difficult to distinguish
even after the valuable revision of it by TATE REGAN, which
was the first attempt to bring order in the former chaotic
state of species. Most of them show a confusing variability of
characters according to size, sex and locality and seem partly
not yet to be fixed. The following key to distinguish them is
therefore not very satisfactory.

dorsal scales from snout. The 5th to 7th or 8th dorsal ray
strongly produced and reaching on caudal. Anal with a basal
sheath of one row of small scales, which may increase to 1'/,
or 2 irregular rows, by interpolation of smaller ones. Anal
rays, before the 2 or 3 last short ones, increasingly produced,
so that they even may reach nearly to end of caudal. Caudal
large, its central rays produced. The filamentous lengthening
of the median fins varies individually (with sex?) and increases

darker, otherwise light brown with numerous more or less
distinct dark lines, corresponding with the transverse series of
scales above anal sheath, usually more accentuated by a series
of corresponding dark spots. In small specimens the successive
4th or 5th transverse line may be fainter, what gives the im-
pression of broad, not pronounced dark crossbars; small spe-
cimens may also have a broad dark longitudinal band from
snout to caudal in the middle of the side. A black spot behind
chin. Branchiostegal membrane blackish or isthmus with a
blackish patch, which may increase to a band from eye to
eye. Fins dusky, but the dorsal may have series of dark spots
or longitudinal bands. Length 115 mm. [Specimens of 4. anaba-

Note: A collection of about 150 specimens in the Museums
of Leiden and Amsterdam from BLEEKER’s collection and
359
named by him ‘4. picta Blkr.”, with the colour faded and
mostly in a bad state of preservation, contains specimens
belonging without question to 4. picta C. V. = B&B. trifasciata Blkr.
More numerous are the specimens belonging to B. anabatoides
Blkr. A few of them show still the markings of the dorsal as
drawn in the otherwise rather bad figure in BLEEKER’s Atl.
ichth. on which TATE REGAN founded 2. Bleeker?. REGAN
in his valuable revision of the genus Zefta not having had
the opportunity of seeing the original specimens of BLEEKER,
was misled by BLEEKER’s figure and his very insufficient
description in his last paper (Verh. Akad. Amsterdam XIX.
1879, Poiss. pharyng. labyrinth. p. 26), in which he united
his former 4. anabatoides and trifasciata under the name &. picta.
His diagnosis, taken from 2 different species, was of course
erroneous and misleading.

shorter than the flat interorbital space. Maxillary extending
about to vertical through posterior nostril. Origin of dorsal
usually nearer to head than to base of caudal, opposite to
14th—r5th lateral scale and separated by 20—24 praedorsal
scales from snout. Second or third penultimate rays more or
less produced and then reaching root of caudal. Anal with a
low basal sheath of one series or two irregular series of scales; its
posterior rays preceding the last more or less produced, reaching
on anterior third of caudal. Caudal rounded or pointed, the
middle rays being produced. Pectorals rounded, 1.6—1.7 in
length of head. Height of caudal peduncle at base of caudal
1.7—2 in length of head. Colour variable. Yeilowish to lighter
or darker brown. Back darker. Belly often reddish. According
to state of preservation, sexual maturity and probably also
locality the colouration is influenced. There are always present
3 dark longitudinal stripes, sometimes produced by black edges

of the scales, on one continuous series of scales. The middle one
runs from base of caudal, where it often begins with a round patch,
through eye to snout, from where it is usually continued as
a dark band along the chin to the other side. The superior
band commences on operculum and runs to caudal, the inferior
from below base of pectoral to caudal, anteriorly usually
continued as a series of a few black points to hindborder of
eye. A transverse band crosses the isthmus and connects the
lower border of the eyes, it may be missing or obsolete. In
Sumatran species the underside of head is more or less blackish.
Pectorals near base with or without a transverse band. Inner
rays of ventrals blackish, anal and caudal with or without a
black margin, sometimes with one or more series of elongate
spots. Dorsal with or without dark longitudinal points, which

Rostro-dorsal profile straight from dorsal to nape, from there
to snout slightly declivous. Height 3.5—4.2; head 3.6—4.5 in
length. Eye 3—4 in head, conspicuously longer than snout,
1.6 to twice in postorbital part of head and less than 1'/, times
in convex interorbital space, which goes 2.6—3 times in length
of head. Maxillary extending somewhat before or behind vertical

to head, opposite to 18th or rgth lateral scale and separated
by 28—30 praedorsal scales from snout. Fifth to 7th dorsal
ray produced, reaching caudal or on it. Anal with a low sheath
of one series of scales at its base; its 2 or 3 prepenultimate
rays produced, even to last third of caudal. Caudal large, spoon-
shaped, its central rays produced. Pectorals round, rather large,
not much shorter than head. Height of caudal peduncle at
base of caudal about 1.3 in length of head, much longer than
its postorbital part. Lighter or darker brown, with about 6,
more or less distinct, often faint, darker crossbars. Fins dusky,

Note. We found in the collection of BLEEKER in the Leiden
Museum in a bottle containing numerous specimens of Letta
and named by BLEEKER JZ. picta the above described species.
We are not sure that it is really &. dellica Sauv. as its des-
cription by SAUVAGE is very short and the accompanying
figure probably not very good, but our specimen comes nearest
to this species.
Doubtful species.
Betta pugnax (Cant.).
Macropodus pugnax Cantor, Cat. Malayan Fishes, Journ. Asiat. Soc. Bengal

This species is mentioned by the following authors from
different localities in the Archipelago: by VON MARTENS ')
(Borneo: Seminis); KAROLI?) (Borneo: Palandok, Matang);
BOULENGER #) (Sumatra: Deli); VAILLANT +) (Borneo: rivers
Kapuas, Knapei, Sebruang, Mahakam); VOLZ”°) (Sumatra:
Palembang, Benakat, Lahat, rivers Mahé, Kwantan, Si Russi
and at Indragiri, Tandjung Butus and Upper and Lower Langkat);
FOWLER °) (Borneo: Baram river).
All the quoted authors give no description and as their
publications appeared before the valuable revision of the genus
Betta by TATE REGAN, who mentions as habitat for B. pugnax
only Pinang, it is impossible to make out what species is meant
by the quoted authors, PERUGIA ‘) gives a very short description
of specimens found in Sumatra and named by him 4. pugnax,

Note. Mr. A.C. KRuyT informs us, that this fish is caught
by hooks in November, December and January, when great
shoals of it are living in depths of 12 to 15 m. This is the
season of propagation as the caught fishes immediately discharge
their eggs. As soon as the eggs are extruded, the young fry
is hatched and swims with the mother. In the period of
spawning, the broken eggmembranes, rising to the surface, cover
extensive stretches of it and are called by the Toradjas
“momosonja’’.

1) The arrangement of these parts of the upper jaw was only clear to us, after
we had examined Xenopoecilus. This explains the different interpretation by one
of us, when describing the genus. We believe now, that the bone described
there (see fig. 98) as intermaxillary, is an artefact, caused by two symmetrical
cracks in the real intermaxillaries.

(either right or left) the anus opens. The genital papilla opens
on the opposite side. The priapium is supported by one or
both cleithra and the first pair of ribs or one of them, these
bones being modified. Moreover the priapium is provided with
a complicated structure of bones, with special muscles. Of
382
these bones one or two curved rod-like ones (ctenactinium)
are situated outside the priapium, at the aproctal side, and
attached to it posteriorly. An other bone (toxactinium) in front
of the priapium, may be present ').
Distribution: Two genera with three species are known
from brackish water of Malacca and Singapore.
I. Neostethus Tate Regan.
(C. TATE REGAN, Proc. Zool. Soc. London 1916, p. 2).
Elongate, strongly compressed. Head rather small. Mouth
terminal, strongly oblique. One or two series of conical teeth
in the jaws. Dorsal fin with 5 or 6 rays, above the end of
the rather long anal, which has 13—16 rays. Pectorals placed
rather high. Ventrals wanting, perhaps represented by a pair
of papillae just behind the anus in the female. Caudal emar-
ginate. Anus, genital aperture and urinary opening behind
each other in the middle line below base of pectoral fins in
the female; behind them the abdomen is compressed into an
edge bearing a rayless fringe. In males the priapium is attached
for the greater part of its length to the head and anterior part
of body, only the posterior end being free. One or two ctenac-
tinia present. No toxactinium. A glandular longitudinal groove
along the upper part of the priapium, at its aproctal side and
continued behind into an efferent groove. Seminal papilla
opening into the glandular groove or into the efferent groove.
Distribution: Two species known, from the Malay Penin-
sula and Singapore.

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”’.
