head without snout, its spine somewhat shorter, denticulated 

 at its hind border 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). 



In rivers and lakes.

Moderately elongate, compressed, head conical, profile sloping 

 down from dorsal to snout, nearly straight. Height 4 ] / 5 4 4 / 5 , 

 head about 4 3 / 5 . 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,
