blackish; 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 flows into Lake Michigan." (Cope.) 

 A little-known species apparently close to Coitus leldingii. On the types 

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

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

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

 hooked. The spots on the body are less sharply denned than in Coitus 

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

 Fish. N. A., 111.) (6Tti\ooTO^ spotted.)

Head 3* ; depth 5$. D. VII-17 ; A. 12 ; P. 13 ; V. I, 4. Eye 4J ; snout 3J- ; 

 interorbital width 7. Least depth of caudal peduncle about equaling 

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

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

 wide strip visible laterally in the closed mouth. Preopercular spines 

 entirely absent, the preopercular margin evenly rounded throughout, 

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

 a very narrow band of teeth; palatines naked; skin wholly naked; lat- 

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

 low, the pectorals barely 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) If 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 C.philonips; dorsal bars indistinct; 2 narrow black lines 

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

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

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

 Coitus philonips, but remarkably distinguished by the lack of preopercular 

 spines. (Gilbert & Evermann.) (Ao, smooth; rt&jua, opercle.)

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

 greatest width of head but j- or $ more than its depth at occiput. Mouth

 crossing eye in front of pupil, 2 to 3 in head. Eye equaling snout, 41 in
