B. spilopholis with those of most other Barbels we must consider them as 

 small, though they are large compared with those of B. j)rogastus. The whole 

 of our Indian Barbels, as well as Cirrhins, will however require much further 

 investigation and revision. 



The scales of Cyprinus chagunio, Buch. are spotted at the base, and the 

 head is compressed, with round tubercles distributed on its fore part. The fin 

 rays are,

Colours above green, below silvery. It was found by Buchanan in the Jumna 

 and the northern rivers of Behar and Bengal, and is said to be an excellent 

 food.

General figure short, head blunt, mouth directed obliquely upwards, 

 suborbitar plates narrow, thirty-four scales along the lateral line, and eleven 

 in an oblique line from the base of the ventrals to the back. Dorsal pre- 

 ceeded by a spine finely serrated behind. Fin rays are,

Colour bluish grey above, but bluish white beneath, with a diffuse golden 

 stain on the operculum. 



The stomach of this species extends the whole length of the abdominal 

 cavity, and contracting slightly terminates in an intestine of moderate length, 

 which is merely reflected once a short way back upon the stomach and thence 

 is extended to the vent. 



The ordinary length of the species is about ten inches. It is found in 

 languid streams on sandy bottoms in Upper Assam, and is considered an 

 article of luxury from its fine sweet flavour, wholesome qualities, and probably 

 also from its comparative scarcity. It is one of those species that might be 

 introduced with advantage, and propagated extensively in fish ponds in Upper 

 India. It seems to approach very nearly to the Perilamps, as well from its
