Cyprinus gohama, Buch. Cyprinus dyangra. id. Coll. 



This species I have not met with, but it has been found by Buchanan 

 in the Kosi river, in the north-western parts of Bengal, as well as in the 

 Ganges. It appears to differ from the former in being of shorter proportions, 

 and by having one ray more in the anal fin, which with the ventrals and 

 pectorals are thin and pelucid ; only that Buchanan states that it contains two 

 cirri, his description might be referred to G. gohioides. 



In his collection of figures, however, Buchanan seems clearly enough to 

 point out the species to which he alludes in his description, although he has 

 there given it a different name.

This species has the under surface of the head flat, with a cartilaginous disk 

 or sucker behind the mouth ; snout broad, smooth, depressed, with a row of 

 open pores extending round the snout between the nostrils, and another row be- 

 tween the eyes; mouth very small, vertical, and fleshy; pectorals round; fin rays 

 short, soft, and the membrane in which they are enveloped thick and opaque.

Colour yellowish white below, and dark brown above, without spots. Thirty- 

 five scales along the lateral line, and nine rows on either side between the dorsal 

 and ventrals. The specimen from which this description has been taken -vvas 

 found by Mr. Griffith in the Laeeh river a few miles beyond Bramacund, at an 

 elevation of 1000 feet in the Mishmee mountains, lat. 27° 45' N. long. 96° 20' E. 



The abdominal canal is very narrow, and about eight lengths of the body.
