INDIAN CYPRINID^. 



II. Gen.—ABRAMIS. 



Char. Body short and elevated, a short dorsal is placed opposite to the 

 ventrals, colours plain, anal long. 



Obs. One species only has hitherto been discovered in India. 



Spec. Cyp. cotis, Buch. P. G. PI. 59- f. 93. 



Body silvery white, scales very small, a small black spot is 

 situated at the base of the dorsal. The fin rays are D.IO : 

 P.13 : V.iO: A.32 : C.19.* 



III. Gen.— PERILAMPUS,! J M. 



Char. Head small, obliquely raised above the axis of the body ; dorsal 

 placed opposite to a larger anal ; apices of the jaws raised to a line with the 

 dorsum, which is straight ; the ventral margin is much arched ; sides usually 

 streaked with blue ; fins without spinous rays. 



Obs. In this genus the intestine is small, and very little longer than 

 the body. The species all subsist exclusively on insects, which they seize 

 by leaping above the surface. They vary from two to four inches in length. 



In the first two species, the altitude of the body is equal to half its 

 length. 



S'pec. Cyp. devario, Buch. P. G. t. 6. f. 94. 



Back arched, sides marked with a single interrupted blue 

 streak. D.18 : P.IO : V.8 : A. 18 : C.19. 

 Hab. Bengal and Assam. 



* Buchanan makes the fin rays D.IO : P.16 : V.12 : A.36 : C.I9. the discrepancy depends on the 

 difficulty of counting the rays in some of the fins of this small species.
