LEUCISCUS. 185 



GEN. LEUCISCUS. 



Roach, — Leuciscus Rutilus. This fish inhab-

 rivers in the interior of New Hampshire, Vermont, 

 and Massachusetts, this side of Connecticut river. 

 Prof. Hitchcock, of Amherst College, has polite-

 dace, which appear to be very common in that 

 vicinity. 



We have not been able to procure any that ex- 

 ceed eight inches. Small as they are, they are

Bleak, — Leuciscus Alhurnus. This, too, is
