The dorsal profile in this fish rises from the tip of the snout 

 to the base of the dorsal fin beyond which it runs straight to 

 the base of the caudal fin ; the ventral is somewhat convex. 

 The head is flattened on the under surface and is i'2 times as 

 long as broad ; its length is contained 4-9 times in the length of 

 the fish without the caudal. The depth of the body near the 

 origin of the dorsal fin is equal to the length of the head. The 

 eyes are almost in the posterior half of the head and look out- 

 wards and upwards ; their diameter is contained 4 times in the 

 length of the head, 2"i times in the length of the snout and 2 times 

 ill the interorbital width. The snout is broad and semicircular and 

 the nostrils are situated in its posterior third. There are two pairs 

 of short barbels, shorter than the diameter of the eye in length. 

 The mouth is on the under surface considerably behind the anterior 

 end of the snout and is provided with well-developed upper and lower 

 labial folds. The mental disc is oval, its longitudinal diameter 

 being half the transverse diameter. The origin of the dorsal finis
