348 TELEOSTEI. PHYSOSTOMI. 



This fish shows considerable alterations in colour and form as it 

 gets older, there are likewise individual variations that have been 

 considered species. 



Variety cocsa (Cyprinus cocsa, Ham. Buch.) shows rather a deep 

 third suborbital bone, the eyes a little larger ; the dorsal, pectoral, 

 and ventral not so developed as in the next variety. The size of 

 the axillary process and the presence or absence of bars on the 

 back are subject to individual variation. 



Variety chedra (C. chedra, Ham. Buch.) has the third suborbital 

 less deep than in the preceding form, the dorsal, pectoral, and 

 ventral more developed, and the axillary process larger. The outer 

 pectoral rays are very stiff. 



The ova of this species are large ; I found the fish breeding at 

 Cuttack, in the month of November. 



Hob. Assam and Himalayas, through the continent of India as 

 far as the Western Ghats, not recorded from the coast of Malabar 

 or Canara nor from Sind. Found also in Ceylon, whence Dr. 

 Kelaart brought some specimens to the museum of the East-India 

 Company. The species attains at least 6 inches in length.
