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. 



Genus URANIDEA De Kay 



Preopercular spines small; usually no trace of teeth on palatines; ven- 

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

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



URANIDEA KUMLIENII Hoy 



Hoy, 1876, in Nelson, Bull. 111. State Lab. Nat. Hist., I. 1, 41.

Length 23^ inches; body slender, gradually tapering to the rather 

 slender caudal peduncle; depth 5 to 5.2; width slightly less than depth; depth 

 caudal peduncle 2.2 to 2.4 in its length. Color brownish olive, faintly 

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

 blotch on anterior and posterior two or three membranes; membranes of 

 soft dorsal dusky toward base; pectorals reticulated with dusky. Head 

 rather flatfish above, but more convex than in Cottus ricei, 3.1 to 3.4; as wide 

 as long; interorbital space 7.5 to 8.6; nose 3.3 to 3.6; mouth rather narrow, 

 but large, maxillary to middle of orbit, 2.2 to 2.4 in head; preopercular spine 

 about half of eye; lower spines not prominent; isthmus not greater than eye; 

 palatines without exposed teeth. Dorsal VII or VIII, 15-17; first dorsal 

 % height of second; caudal narrow, spatulate; anal 12; pectorals to front of 

 anal. Body nearly smooth; top of head and axils with some prickles; lateral

 pores on caudal peduncle sunken and inconspicuous). 



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, snowing
