head without snout, its spine somewhat shorter, denticulated 
at its hindborder and at the top of its frontborder. Height 
of adipose fin a little less than diameter of eye, opposite to 
end of anal, the length of which goes more than thrice in 
length of body. Ventrals extending to anal, about equal to 
postorbital part of head. Pectorals a little shorter than dorsal, 
their spine still shorter, very strong and strongly denticulated 
at its inner border. Minute teeth in narrow bands on the jaws; 
on the vomer in two small patches connected by an angular line 
of teeth. Yellowish, a blackish band in the lateral line, a less 
distinct but broader band below and above it, the latter more or 
less confluent with a dark median band on the back. A distinct 
black blotch at the origin of dorsal. Upper surface of head, 
mandibles, caudal, margin of anal and part of the remaining 
fins darkish. Length 115 mm. 
Habitat: Sumatra (Palembang, Djambi!); Borneo (Danau 
Sriang).

Moderately elongate, compressed, head conical, profile sloping 
down from dorsal to snout, nearly straight. Height 4'/,—4"*/,, 
head about 4°/,. A median groove running from the snout to 
the end of the occipital process, but separated in two on the 
vertex by a transverse constriction. Occipital process separated 
from the first interspinal bone. Jaws equal. Eye 3—4, situated 
behind the corner of the mouth and partly below it, about 
equal to the flattish interorbital space. The nasal barbels 
reach as far as the depressed dorsal. Maxillary barbels near 
the corner of the mouth, extending to the anterior part of 
the anal, as is also the case with the mandibulary and mental 
barbels which originate in approximated pairs immediately be- 
hind the border of the upperlip. Dorsal a little longer than head 
without snout, its weekly denticulated spine distinctly shorter. 
Height of adipose fin equal to the diameter of the eye, situated 
before the end of the anal, the length of which goes more 
than twice in the length of the body. Ventrals about equal 
to postorbital part of head, reaching anal; their origin just 
behind dorsal. Pectorals about equal to head without snout,
