322 INDIAN CYPRINID. Peonomine. 
existence of several varieties of this species, I thought Buchanan’s figure the 
very worst imaginable, in as much as it does not correspond with his descrip- 
tion; in proof of which it is only necessary to mention that although he 
correctly says the mouth extends straight backwards, i.e. horizontally, yet the 
figure places its orifice under the head half way between the snout and the 
eyes, as in the Gonorhynchs; but when the mouth of C. rohita is closed, the 
upper lip, which is rather thick and muscular, is drawn in front of the orifice 
of the mouth like a projecting snout. There is, however, a small sized variety 
very common in Calcutta, which corresponds very accurately in every respect 
with Buchanan’s figure, while his description agrees with a larger fish, probably 
the one I have figured, though there are still other varieties, but they may all 
be considered as one species. The different characters which it presents are no 
doubt the result of domestication. The variety figured by Buchanan is con- 
stant in its characters, and may be described as having two minute cirri, one at 
either angle of the mouth; the length of the head is rather less than the depth 
of the body, which is almost equal to a third of the length. The back is green 
and gold coloured, diminishing on the sides; the upper part of the head, the 
dorsal, caudal, and anal are dark olive, the pectorals pale, ventrals red. There 
are forty-three scales on the lateral line, and twelve from the base of the ven- 
trals to the dorsum. The fin rays are,

This is the Ruee figured by Buchanan. The following description refers to 
the one I have figured which is much larger, and very common in Assam; and 
it seems to me that Buchanan’s description applies more to the latter than the 
former variety. I have stated the rays of the anal to be eight, while Buchanan 
makes them seven; the last ray of that fin is usually double, and sometimes 
it is difficult to say whether there be one ray more or less than a given 
number.
