Fius. — The height of the dorsal fin equals the length of the head, 

 its upper margin is very concave, it commences before the ventrals 

 and midway between the snout and the posterior extremity of the 

 base of the anal fin. Caudal deeply forked, lower lobe the shortest. 



Teeth, pharyngeal, plough-shaped 5, 4, 2/2, 4, 5. 



Scales : — 1\ rows between the lateral line and the base of the 

 ventral fin. 



Colours : — silvery, darkest in the upper half of the body ; some- 

 times the scales are spotted with red. 



Habitat. — N. W. Provinces, and Assam in clear streams. It is 

 termed Mohaylee and Gaywah in Hiudoostanee at Hurdwar and 

 Saharunpore. 



It appears to strongly resemble Gobio anisurm, McClelland, 

 which, however, is said to have 39 scales in the lateral line, a 

 rough porous snout, and the lower lobe of the caudal to be the 

 longest; see Cirrhim anisura, p. 136.
