Observations. A full description of this species has been 

 furnished by Dr. Storer, in vol. ii. page 429 of this journal, 

 to which we would refer the reader. 



The specimen before us was taken in the Sault St. Marie. 

 Among half a dozen from that locality there is considerable 

 difference in the size and colors. 



The only localities in which it is found in the state of Ohio, 

 is Chagrin river, in Geauga county, and a small stream that 

 enters Lake Erie at Kingsville, in Ashtabula county. It abounds 

 in the Sault St. Marie in such abundance, that it is taken for 

 exportation. We are indebted to Charles M. Giddings, Esq., 

 of Cleveland, for a number of fine specimens from St. Marys.

 been amply described by Dr. Storer, vol. ii. p. 405 of this 

 journal. 1 shall not attempt to make any additions to his 

 description, but would observe that our western fish is usually 

 of a deep pea-green on its back, and not black. The specimen 

 before me was taken in a bayou of the Cuyahoga river, near
