This species, which is common in Lake Huron, where it is highly prized as food, and is 

 called Slieepshead, also occurs, as I am informed, in Lake Erie. A fish has been described 

 to me at Buffalo and Barcelona, where it is called Black Slieepshead, which agrees well in its 

 savory qualities, color and other characters, with the above species. Feeds on crayfish, etc.
