4.7 4-9> 5-6 5-8 in length with caudal, its breadth about 

 5 / 7 of its length. Eye about 5, twice in interorbital space, 

 more than twice in the snout. Barbels subequal, slightly longer 

 than eye. Origin of dorsal behind origin of ventrals, much 

 nearer to snout than to base of caudal, corresponding to the 

 28th perforated scale of lateral line, separated by more than 

 50 scales from the occiput. Dorsal truncate, its height about 

 equal to that of body. Origin of anal about in the middle 

 between base of caudal and end of base of ventrals, below 

 the 46 th to 5 2nd perforated scale of lateral line. Ventrals not 

 reaching anus, about equal to pectorals. Pectorals much shorter 

 than head, not reaching ventrals. Caudal nearly truncate, about 

 equal to head. Scales on the upper anterior part of trunk 

 much smaller than the posterior ones. Scales on abdomen only 

 behind ventrals. About 12 pharyngeal teeth. Greyish with
