Abundant in the great rivers of the State and their larger tributaries, and 

 also in Lake Miehiirau and the smaller lakes of Northern Illinois. Extremely 

 common in tlie lakes and ponds of the river bottom. 



After prolonged study of the so-called species of native carp represented in 

 our collections, I have been compelled to merge them all in one, ander 

 the oldest specific natue.
