Barhus. INDIAN CYPRINID^. 341 



The colour is green above, below silvery ; scales large. Such are the only- 

 characters of value given of this species by Buchanan, who supposed it to be 

 probably identical with Cij'p. Jmnamoo, Russ., though the dorsal of that species 

 contained only nine, and the anal only seven rays.

Length of the head to that of the body is as one to three, head much 

 compressed, eyes equidistant between the snout and the branchial aperture, 

 suborbitar plates narrow, cheeks and snout porous, the latter abrupt, depressed, 

 and projecting in front of the mouth which is low, narrow, and horizontal ; 

 dorsal margin sharp in front of - the fin ; the third ray of the dorsal finely 

 serrated behind, the last is double. The fin rays are,

Forty-seven or forty-eight scales are placed along the lateral line, and 

 sixteen or seventeen in an oblique line from the base of the ventrals 

 to the dorsum, with a black diffuse spot at the base of each scale ; colour 

 blackish grey along the back, changing to bluish white below. The specimen 

 from Avhich the description and drawing were taken, was presented to the 

 Society by Mr. Hodgson, and had the two last rays of the anal prolonged to 

 extended filaments ; the species is probably the same as the following, which 

 like C. sarana is said to have large scales,* but if we compare the scales of 



* The fin rays of Cyprinm chagunio, Buch. correspond witli those of Cyprimis pitutora, id. ; 

 but in tlie former, the dorsal spine is serrated, and in tlie latter it is sniootiier beliind ; in the former 

 tliere are but twenty-six scales along each lateral line, in the latter forty-eight. The Indian Barbels 

 may be conveniently divided into t« o sections, namely — species with large scales and sniootli dorsal 

 spine, and species witli smaller scales and serrated dorsal spine. This group as well as the Cirrliins 

 requires to bo made the subject of a distinct monograph.
