each are undivided. The anal fin is near the vent, and slopes 

 behind : the first of its rays is very short, and is closely joined 

 to the two following, which, like it, are undivided ; the others 

 are branched, and the last of them is divided to the root. The 

 tail fin contains nineteen distinct rays, besides short compact- 

 ed ones. 



25th Species. — Cyprinus acra. 



A Cyprinus of the Bangana kind, without tendrils ; with 

 eleven rays in the fin of the back, and eight in that behind the

26th Species. — Cyprinus cura. 



A Cyprinus of the Bangana kind, without tendrils ; with 

 twelve rays in the fin of the back, and seven in that behind 

 the vent ; with the under lip smooth-edged, and erect ; and 

 with the lobes of the tail fin equal in length. 



The Cura is another fish so nearly allied to the Bata, that I 

 have only noted the circumstances in which it differs from the 

 account before given. It is found in the rivers of Bengal, and 

 scarcely exceeds the finger in length. The fins are of a yellow- 

 ish colour, and very little dotted. In the fin behind the vent the
