The height of the body is one-fifth of the total length (without 

 caudal), the length of the head one-sixth ; head rather higher than 

 broad, its greatest width being two-thirds of its length ; the upper 

 jaw prominent ; teeth on the palate minute, forming a short sub- 

 crescentic band. Barbels slender, shorter than the head. Dorsal 

 fin as high as the body ; its spine is of moderate strength, striated, 

 about as long as the head. The adipose fin commences at a short 

 distance from, and is more than four times as long as, the dorsal. 

 Pectorals rather longer than the head ; their spine is stronger than, 

 and about as long as, that of the dorsal fin, and strongly serrated in- 

 teriorly ; ventrals shorter than pectorals.

Nape of the neck elevated. The height of the body is contained 

 rather more than four times in Hie total length (without caudal), the 

 length of the head five times and a half; head rather higher than 

 broad, its width being two- thirds of its length. The upper jaw 

 prominent ; the teeth on the palate are very conspicuous. Barbel 

 slender, shorter than the head. Dorsal fin rather higher than the 

 body ; its spine is of moderate strength and much longer than the 

 head. The adipose fin commences at a very short distance from, and 

 is about four times as long as, the dorsal. Pectorals about as long as 

 the head, their spine being as strong as, but much shorter than, that 

 of the dorsal fin, serrated interiorly. Ventrals shorter than pectorals.
