The Bleak is one of the smaller Cyprinoids. Its 

 ordinary length, including the caudal tin, is 13 — 15 

 cm. In Sweden it seldom measures 18 cm.; hut Be- 

 NECKE states that in Prussia it attains a length of 20 cm.' 



The bodj' is rather elongated and laterally com- 

 pressed, the greatest depth being occasionally ^ ^, lint 

 generally between ISV, and 23 %, of the length to tlie 

 end of tlie middle caudal rays, and the greatest thick- 

 ness at most about '/^ the greatest depth. The least 

 depth of the tail measures on an average about 8 * 

 (7-4— 8'2 %) of the length of the body. The dorsal 

 margin is convex throughout its length. The belly is 

 flat in front, carinated from the ventral fins to the 

 anal apei'ture. The dorsal line is "ften nearly straight, 

 being, at least in front, much less curved than the 

 ventral.
