Tlie length from the operculum to the base of the caudal is four and a 

 half lengths of the head, which is small and fleshy. The posterior margin of 

 the operculum is equally rounded forming part of a circle, and the eyes are 

 placed intermediate between the branchial aperture and the snout. The dorsal 

 is placed somewhat nearer to the caudal than to the head, and forty-two scales 

 are ranged along the lateral line, which is but slightly depressed over the 

 pectorals ; fifteen scales form each oblique line extending from the base of the 

 ventrals to the dorsum on either side ; the ventrals are placed a little behind 

 the dorsal. The fin rays are,

It is observed by Buchanan that in some places, as at Moonghyr where 

 the Ganges is clear, passing over a pure sandy or rocky bottom, many of the 

 scales assume a ferruginous colour, and the fish is supposed by the Natives to 

 be a different species, which they call KundJma, though he has no doubt this 

 difference of colour is accidental. Buchanan farther remarks, that this species 

 is very common in all the rivers and ponds of Bengal, and that it is also found 

 in the Western Provinces about a foot and half in length, and sometimes even 

 twice that size, and is a well flavoured light food, but contains many small 

 bones. In general, Buchanan observes, it is of dark colour with a silvery gloss, 

 inclining to yellow, and the scales are covered with numerous black dots. It is 

 a very common fish in the Calcutta market.

The head of this species is a third longer than that of C. calba.su, and is 



equal to the depth of the body, while in the latter species the length of the 



liead is little more than about half that depth. Before I was aware of the
