blaikisli; large lateral round spots of the same color sometimes in 7 

 or fewer cross-bars. Length 3 inches. Several specimens from Grand 

 Rapids, on the Grand River, which ilows into Lake Michigan." (Cope.) 

 A little-known species apparently close to Cottus hdd'mgii. On the types 

 of this species we have the following notes : It has now no evident teeth 

 on the palatines and the ventral rays are I, 3.* The skin is smooth, and 

 the preopercnlar spine, although prominent and directed upward, is not 

 hooked. The spots on the body are less sharply detined than iu Cottus 

 ricei, with which Jordan & Gilbert first identified it. (Jordan, Cat. 

 Fish. N. A., 111.) {dTtiAcoTOi, spotted.)

2334. COTTUS LEIOPOJIUS, Gilbert & Evermann. 



Head Si ; depth .54 . D. YII-17 ; A. 12 ; P. 13 ; V. I, 4. Eye 4* ; snout ^^ ; 

 iuterorbital width 7i. Least depth of caudal peduncle about equaling 

 length of snout; iuterorbital space very narrow, much less than diameter 

 of eye; mouth small, maxillary reaching vertical from middle of eye, a 

 wide- strip visil)le laterally in the closed mouth. Preopercnlar spines 

 entirely absent, the preopercnlar }nargin evenly rounded throughout, 

 without prominence, and without the least trace of a spine. Vomer with 

 a very narroAV l)and of teeth; palatines naked; skin wholly naked; lat- 

 eral line complete. Dorsal fins not joined unless at extreme base; fins all 

 low^, the pectorals liarely reaching front of anal under third ray of second 

 dorsal, its last ray under fourth from last ray of latter. Free portion of 

 caudal peduncle (behind last anal ray) 1| in head; portion behind base of 

 last dorsal ray 3 in head; neither dorsal nor anal reaching base of caudal 

 when depressed. Color in alcohol, head on sides rather finely vermicu- 

 lated with light and dark; plain whitish below; not coarsely spotted or 

 blotched as in Cphilonlps; dorsal bars indistinct; 2 narrow black lines 

 dowuAvard and backward from eye ; an evenly convex dark bar at base of 

 caudal ; dorsals, pectorals, and caudal faintly cross-barred. Length about 

 3i inches. Upper Little Wood River, Shoshone, Idaho. Closely related to 

 Cottus pJiUonips, but remarkably distinguished by the lack of preopercular 

 spines. (Gilbert & Evermann.) (A£?o?, smooth ; TC&jita, o-percle.) 



Vottus leiopomus, Gilbeet & Evermann, Bull. U. S. Fisli Comm. 1894, 203, pi. 20, Upper

2335. ( OTTUS PBIMEPS, Gilbert. 



Head 3i to 3| in length ; depth 5 to 5*. D. VI or VII, 21 to 23. A. 16 to 

 18 ; V. I, 4 ; P. 15. A slender form with small, narrow head, which is nearly 

 qviadrate in cross section, the opercles and cheeks being subvertical, the 

 greatest width of head but k ov ^ moie than its depth at occiput. Mouth 

 small, oblique, the gape slightly curved, the maxillary reaching a vertical 

 crossing eye in front of pupil, 2* to 3 in head. Eye equaling snout, 4J in

perhaps an error iu our notes. The type can not now be found in the collec-
