equal to its length, without snout. The diameter of the eye is 

 about one-fourth of the length of the head, and equal to, or in old 

 individuals a little less than, that of the snout. Barbels very small. 

 Height of dorsal fin not much less than the depth of the body ; its 

 commencement is a little anterior to the ventral, and midway be- 

 tween the end of the snout and the root of the caudal. Caudal fin 

 deeply forked ; the pectoral extends to the root of the ventral. 

 Coloration uniform.

Osseous dorsal ray ■^ery strong and serrated, followed by eight 

 soft rays ; the length of its stiff portion equals that of the head. 

 Four longitudinal series of scales between the lateral line and the 

 root of the ventral. Body oblong, compressed, its height being con- 

 tained twice and three-fifths or twice and four-fifths in the total 

 length (Tvdthout caudal) ; the length of the head is one-fourth of the 

 same. The diameter of the large eye is a Kttle less than the length 

 of the snout, and more than one-fourth of that of the head. Mouth 

 small, with the upper jaw overlapping the lower ; barbels minute. 

 The height of the dorsal fin is conspicuously less than the depth of 

 the body ; its commencement is distinctly behind that of the ven- 

 tral, and midway between the root of the caudal and the end of the 

 snout. Caudal deeply forked; the pectoral reaches to the root of 

 the ventral. The least depth of the tail is a little more than one- 

 half of the length of the head. Coloration uniform.

This fish is so similar to Barbus siaja, that many ichthyologists 

 may be inclined to regard them merely as varieties. The number 

 of barbels is a character without value for establishing genera. One 

 of the two specimens just mentioned has two barbels only, and con- 

 sequently would belong to the BJeekerian genus Siaja.
