jaw overlapping the lower. The posterior barbels are longer than 

 the anterior, which are as long as the eye. Dorsal fin considerably 

 lower than the body ; its origin is opposite that of the ventral, and 

 midway between the end of the snout and the root of the caudal. 

 Anal fin of moderate depth, the rays not reaching to the caudal, if 

 laid backwards. Fork of the caudal fin of moderate depth. Uni- 

 formly coloured; a small round black spot on the termination of 

 the lateral line.

No osseous dorsal ray. There are two longitudinal series of 

 scales between the lateral line and the root of the ventral. Body 

 oblong, its height being contained thrice and two-thirds in the total 

 length (without caudal), the length of the head four times. The 

 diameter of the ej^e' equals the width of the interorbital space, is 

 one-third of the length of the head, and more than that of the 

 snout, which is obtuse. Moixth inferior, small ; the lower barbel is 

 longer than the upper, about as long as the eye. The dorsal fin is 

 elevated in front, about as high as the body ; it commences nearly 

 opposite the origin of the ventrals, and its first ray is equidistant 

 from the end of the snout and the root of the caudal. Anal fin not 

 very narrow ; fork of the caudal fin moderately deep. The pectoral 

 fin extends nearly to the ventral. Sides with about twelve narrow 

 blackish-blue vertical streaks, none of which extends to the back or 

 belly ; the second, midway between the gill-opening and the dorsal, 

 is dilated into a spot ; a small round spot on the middle of the base 

 of the caudal. Base of the anal fin bluish black.

D. 11. A. 8. L. lat. 26-27. L. transv. 4/5. 

 No osseous dorsal ray. There are three longitudinal series of 

 scales between the lateral line and the root of the ventral. The 

 height of the body is contained from thrice and two-fifths to thrice 

 and one-fourth in the total length (without caudal), the length of 

 the head four times or four times and one-fourth. The diameter of 

 the eye is one-third, or somewhat less than one-third, of the length 

 of the head, and not quite equal to the width of the interorbital 

 space. Snout rather shorter than the eye, somewhat obtuse ; barbels 

 scarcely longer than the eye. The origin of the dorsal fitn is opposite 

 to that of the ventrals, and somewhat nearer to the end of the snout
