not much hooked up and not very sharp, a shallow concave space between 

 it and the second, scarcely a notch; the second small and sharp, the third 

 hut slightly developed ; pectoral reaching to below the fourth ray of soft 

 dorsal; ventral not reaching the vent; dorsals scarcely connected, the 

 soft dorsal high, the highest rays equal to eye and snout; vent slightly 

 nearer tail than tip of snout. Skin smooth, except a few scattered prickles 

 under pectorals. Color very dark brown or blackish; sides mottled; top 

 of head uniform blackish ; all the fins more or less mottled, ventrals white 

 or dusky. The following is the fin formula of 4 specimens : Dorsal, IX, 17 ; 

 VIII, 18; IX, 17; IX, 18. Anal, 14; 15; 15; 13. Upper Sacramento Basin 

 about Mount Shasta. Here described from 4 specimens from McCloud 

 River, at Baird, Shasta County, California, about 4 inches in length. The 

 species is very close to Coitus semiscaber, but it has a longer anal, which in 

 turn is shorter than in Coitus yulosus. (Named for Mount Shasta.)

2319. COTTUS PUNCTULATUS (Gill). 



Head 3 ; depth 4f. D. YII or VIII, 17 or 18 ; A. 11 or 12 ; eye 6 in head ; 

 maxillary If; third dorsal spine 3; highest ray of soft dorsal 2|; highest 

 anal ray 2J ; pectoral 1 ; ventral If ; caudal If. Body tapering into a 

 slender caudal peduncle which is not much wider than eye ; teeth in wide 

 bands on jaws, vomers, and palatines; interorbital space rather wide, 

 about equal to eye; maxillary reaching to posterior margin of eye; pre- 

 opercular spine rather sharp ; vent slightly nearer tail than tip of snout. 

 Pectoral reaching to below base of fourth ray of soft dorsal; ventrals not 

 reaching vent ; dorsals scarcely connected, the soft dorsal extending far- 

 ther back than anal; skin in these specimens entirely smooth. Color oli- 

 vaceous, everywhere punctulate with black spots, more conspicuous on 

 top of head; tip of snout and lower jaw dark, dusky with dark points 

 under lower jaw; dorsals, pectorals, and caudal with wavy streaks and 

 series of spots; anal and ventrals white, anal sometimes dusky; 4 or 5 

 dark blotches on back indicating cross bars; a dark bar at base of caudal. 

 Length 4 or 5 inches. Headwaters of Green River, Wyoming. Here 

 described from many specimens from Green River, Wyoming, collected by 

 Evermann & Rutter. This species will prove to be a local or desert vari- 

 ation of the widely distributed Cottus semiscaber, from which it differs 

 only in the slender caudal peduncle and the speckled coloration. The 

 name punctulatus has priority over semiscaber, if the forms are to be united, 

 but in this case it would hardly be worth while to separate either from 

 Cottus ictalops. 



Gilbert & Evermann refer to the specimens here described as 

 Numerous specimens from Green River, Wyoming. Comparing these 

 with typical semiscaber from the vicinity of Pocatello, Idaho, we can appre- 

 ciate no difference whatever, except in the matter of armature. None of 

 our Green River specimens shows any prickles whatever. About half the 

 Pocatello specimens are also naked and are indistinguishable from typical
