below ; dorsal and ventrals are opposite. The lobes of the caudal are equal in 

 length. The fin rays are, 



D.ll or 12: P.16: V.9: A.7 or 8: C.19. 



There are thirty-nine scales along the lateral line, and thirteen from the base 

 of the ventrals to the dorsum. 



The liver is situated in the anterior part of the abdomen, immediately 

 behind the diaphragm as usual, in conjunction with the stomach ; the 

 alimentary canal and stomach form a long and narrow tube, equal to eight or 

 nine lengths of the body. The usual size which this species attains is from 

 four to twelve inches in length, it is found in all the fresh waters through- 

 out Bengal and Assam.

This species bears so striking a resemblance to the figure Buchanan has 

 given of Cypr 'mus arim, that I have thought it unnecessary to attempt a bet- 

 ter representation of it, although there is no reason to suppose it to be the 

 Cyjjrimis ari%a which Buchanan has described ; on the contrary, it appears to 

 me to be quite distinct from that species, in which the snout is rough, soft, 

 and perforated by numerous mucous pores, while in this it is smooth, hard, 

 and without pores. It corresponds with G. limnopJiilus in the number of its 

 scales, but in that species there is a distinct tube passing along the middle of 

 every scale on the body, as well as on that row which forms the lateral line, 

 and to which such tubulated scales are usually confined ; so that Gohio 

 limnopMlus has as many lateral lines as there are rows of scales on the sides, 

 Avhile in this species the tubulated scales are confined to the lateral line alone. 



The length of the head is equal to two-thirds of the depth of the body, and 

 a fourth of its lengtli ; the scales are large, and disposed in rows, of wliich there
