The above described species I discovered in Lake Erie, 

 on the 14th of July, 1814. It is an esteemed fish, and is 

 commonly known under the name of the Dog-fish, and Eel- 

 pout. My specimen was two feet four inches in length." 



Observations. Le Sueur is incorrect in giving this species 

 the common name of Dog-fish — that term is exclusively ap- 

 plied to the Amia calva. 



The Eel-pout is an eatable fish, but is far from being es- 

 teemed, its flesh being dry, tough, and not highly flavored. 

 It is taken in considerable numbers about the harbor of 

 Cleaveland, by hooks and seines.
