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 ventrals, 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.
