328 FISHES OF ILLINOIS 



the fish a buffalo-like appearance; isthmus twice eye; palatine teeth obscure 

 (present in Nelson's type). Dorsal VII, 16, the first % height of second; 

 caudal spatulate; anal rays 13; pectorals to front of anal. Body scaleless, 

 axils and top of head with prominent spinules: lateral line continuous. 



Here described from a single specimen taken by the senior 

 author in 1881, from a depth of 600 feet in Grand Traverse Bay, 

 off Old Mission, Mich. Lacking access to Mr. Nelson's type, 

 we refer the present specimen to C. ricei, notwithstanding 

 disagreement with Nelson's description in one or two particu- 

 lars, our specimen lacking the dorsal carination described by 

 Nelson, and having the head smooth.

 trals reduced to a concealed spine and 3 soft rays; otherwise as in Coitus.

 mottled (in preserved specimens); spinous dorsal with a prominent dusky

Described from 3 specimens, taken in deep water in Traverse 

 Bay, off Old Mission, Mich., by the senior author in 1881. 

 Our specimens have not the lower jaw projecting, as called for 

 in original description. Careful comparison with examples of 

 U. gradlis from McLean, New York,* has been made, showing
