This is a large wholesome fish, much resembling the European Carp, but 

 without the dorsal spine of that species. It is very nearly allied to Buchanan's 

 Cyp. nanclina, but has three rays less in the dorsal fin, and other slight pecu- 

 liarities, which may however be mere variations arising from artificial pro- 

 pagation, or other causes. 



The length of the head to that of the body, exclusive of the head and 

 caudal fin, is as one to four, and the greatest depth is equal to one-third of the 

 length. The dorsal fin commences at the most prominent part of the back, 

 at a distance from the head equal to about a third length of the body, and 

 extends to within half such distance from the caudal. 



The ventrals are placed in the middle of the body, somewhat behind the 

 commencement of the dorsal and the anal, on the posterior third of the space 

 between the ventrals and the insertion of the caudal. The base of the dorsal 

 fin is equal to nearly twice the length of the head ; the first of its rays is 

 scarcely half the length of the second, but all the rays are comparatively shorty 

 and the membrane of the fin thick and strong. The fin rays are,

There are forty-one scales along the lateral line, and thirteen in an oblique 

 row from the base of the ventrals to the back. The head is larger in every 

 respect than that of C. calbasu, Buch., but shorter and blunter, as well as more 

 bulky, than that of C. rohita, Buch. The posterior margin of the operculum is 

 the segment of a circle whose centre is situated on the lower and posterior
