between them. Thus, the snout of the Dace is less sharp, and 
the lower jaw not so much protruded. The dorsal fin is 
somewhat nearer the tail in the Bleak, and when laid down 
the end of the dorsal is over the middle of the anal, where, 
as in the Dace, this fin reaches only to the root of the first 
ray of the anal. The upper rays of the pectoral fin reach 
almost to the vcntrals, which is not the case in the Dace; and 
the ends of the divisions of the tail are much pointed. The 
colour of the Bleak is light brown or greenish, the sides and 
below brilliant white; the fins dusky. In the dorsal fin are 
ten or eleven rays, in the anal eighteen to twenty, pectoral 
sixteen, and in the ventral nine.
