the Cirrhins ; the remaining species of Cyprinus prop. may be formed into a 
natural group characterised by a long dorsal and the absence of cirri: view the 
subject as we may, however, Cyprinus devario, Buch. is not only different

The depth is almost equal to half the length of the body; the back is 
straight from the snout to the caudal, and the lower margin or abdomen is 
much rounded and protuberant; the head is small, directed obliquely 
upward, the body much compressed, and the sides are marked with several
