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.; but Be- 
necke states that in Prussia it attains a length of 20 cm3 
The body is rather elongated and laterally com- 
pressed, the greatest depth being occasionally 1 / i , but 
generally between 1 8 x / 2 and 23 %, of the length to the 
end of the middle caudal rays, and the greatest thick- 
ness at most about Vs 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 tins to the 
anal aperture. The dorsal line is often nearly straight, 
being, at least in front, much less curved than the 
ventral.
