last is divided to the root. The fin behind the vent has seven- 

 teen rays, of which the three first are undivided, the second 

 being longer than the first, and shorter than the third. The 

 tail fin ends in a small sinus, and contains twenty distinct rays, 

 besides four short compacted ones on each side, in all twenty- 

 eight. 



58th Species. — Cyprinus berio. 



A Cyprinus of the Danio kind, with several blue and silver 

 stripes on each side ; with the body much compressed, and 

 with four tendrils, of which two are a little longer than the 

 head. 



This beautiful fish I found in the Kosi river, where it grows 

 to about two inches in length. The form is oblong, projecting 

 more below than above. The colour above inclines to olive, 

 and below to silver, with several longitudinal blue and silver 

 stripes alternating on each side. The fin behind the vent is 

 barred, and that of the tail striped with blue. The eyes are 

 silver. 



The head is small and half oval. The mouth descends ob- 

 liquely backward, and is of moderate size. The jaws protrude 

 in opening, the under one being rather the longest. The two 

 tendrils before the nostrils are very short ; the two from the 

 corners of the mouth are a little longer than the head. The 

 eyes, placed on the sides of the head, are of moderate size, 

 with circular pupils. The gill-covers do not conceal their mem- 

 branes. 



The back, from the fin to the head, is straight, and the breast 

 convex. The lateral line is scarcely observable. The scales are 

 of moderate size. The vent is rather behind the middle. There 

 are no scale-like appendants above the lower fins. 



The fin of the back is behind the middle, and is rounded. It
