328 FISHES OF ILLINOIS 



ance; isthmus twice eye; palatine, teeth obscure (present in Nelson's 

 type). Dorsal VII, 16, the first § height of second; caudal spatulate; anal 

 ravs 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 particulars, our specimen lacking 

 the dorsal carination described by Nelson, and having the head 

 smooth.

 Coitus. Cold streams and springs of the United States; species 9 or 10; 

 size small.

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. gracilis from 

 McLean, New York,* has been made, showing that our specimens
