306 Fishes of the Ohio 



Cleveland, where it never attains a greater size than is repre- 

 sented in the plate, but it abounds in some of the small lakes 

 in Portage and Summit counties in this state, and there fre- 

 quently is as large as those found in the waters of the Atlantic 

 states. 



It is a matter of uncertainty what fish Rafinesque had in 

 view when he described his Luxulus crysohucas. His de- 

 scription does not apply to this species nor to any with which 

 I am acquainted. 



In strict conformity to Rafinesque's arrangement, this spe- 

 cies should, perhaps, have been placed under his genus Rutilus.

 behind the base of the head, thence rectilinear to the dorsal

Observations. This species in its contour resembles some- 

 what the Leuciscus crysohucas of Mitch, but its color, the num- 

 ber of rays in the caudal fin, and its more compressed form, 

 will readily distinguish it.
