caudal. — Teeth, : pharyngeal, curved, pointed, 5, 3, 2/2, 3, 5. Colours, silvery 

 with a lateral band which fades after death. 



Sab. — Bowany river at the base of the Neilgherries, attaining 6 inches 

 in length. 



Dr. Jerdon gives about 50 scales in C. diffusa, along the side, and 

 observes that his species is found in the Cauvery and all its tributaries. 

 I did not obtain it in the lower portions of the Cauvery, but C. argentea 

 was likewise absent, and I suspect the two are identical.
