of the ventral. Body compressed, elongate ; its depth is equal to the

 Snout rather elongate, longer than the eye, which is more than 

 one-fifth of the length of the head; interorbital space flat, upper 

 jaw overlapping the lower; barbel as long as or slightly longer 

 than the eye. Dorsal considerably lower than the body ; its origin 

 is opposite to that of the ventral, and midway between the end of the 

 snout and the root of the caudal. Anal fin of moderate size ; caudal 

 deeply forked. Light brownish above, silvery below ; the membranes 

 between the scales brownish ; a black spot at the base of the caudal

The osseous dorsal ray is feeble, unserrated, longer than the head, 

 without snout. There are three longitudinal series of scales between 

 the lateral line and the ventral fin. Body compressed, oblong, its 

 depth being contained twice and four-fifths in the total length 

 (without caudal), the length of the head being two-sevenths of the 

 same. Snout moderate, equal to the eye, which is two-sevenths of 

 llie length of the head ; interorbital space convex ; upper jaw 

 slightly overlap{)ing tlie lower ; barbel shorter than the eye. The 

 height of the dorsal fin is only two-thirds of that of the body, its 

 origin opposite to that of the ventral, and midway between the end of 

 the snout and the root of the caudal. Anal fin of moderate size ; 

 caudal forked. Brownish above, silvery beneath ; the membranes 

 between the scales brown. A black spot on ench side at the base 

 of the ca\idal. Dorsal fin with a diffused blackish blotch near the

Valenciennes has evidently overlooked the barbels. Lateral line 

 distinct to the end. This species may be the Systomus carnaticvs of 

 !Mr. Jerdon ; but the description given by this gentleman is so in-
