56. Perea flavescens Mitcbill. Abuiidaut. at Fort QTi’Ai)pelJe; Brandon. 
57. Stizostedion vitreum (Mitchill). Wintiipeg, Moose .Jaw, Fort Qii’Appelle. A single sjieoimen 
from Moose Jaw lias tlieside.s and upper parts all (piite dark with few yellow siiots in streaks. 
Spinous dorsal dusky with the usual black spots. Soft dorsal, caudal, and pectoral colored 
like the sides; anal and veutrals yellow with many dark s^iot.s. D. xv-1, 21. 
58. Stizostedion canadense griseum DeKay. Wiuuijieg, Brandon, Poy)lar. 
59. Aplodiiiotus gruaniens Rafinesque. Winnipeg, almudant. 
60. Cottu.s asper (Richardson). Mission, Sicaiuous, Kamloops, Grittiu Lake, and Umatilla. Very 
abundant in the Fraser system from tidewater to an altitude of 1,900 feet. This species 
varies greatly in color in dllfereut localities. At ^Mission I obtained a number iu the turbid 
water of the Fraser. These are gray with the usual dark markings; I obtained two specimens 
from a little brook of clear water which were very much darker, the gray remaining as but 
narrow’streaks and spots among the general ground color of black both on the sides and fins. 
61. Cottus bairdi punctulatus Gill. Craig, Montana. 
62. Cottus rliotheus (R. Smith). Two tine specimens of this species, 120 mm long, and a number of 
smaller ones were obtained at La Grande. Lateral line complete. D. > ii or viii, 17; A. 121 
or 131. Soft dorsal adnate behind, the membrane extending to near caudal. Color of largest 
sioecimens: soft dorsal with oliliijue bars, most marked on the rays; caudal with about three 
large bars. The species is quite common at Idaho Falls. 
63. Cottus philonip.s Eigeumaun & Eigenmaun. 
Cottus philonips Eigenmaun A Eigenmann, Am. Nat. 963, 1892. Field. 
Seventeen sx>ecimens of a Coitus were taken in the icy waters of the Kicking Horse at Field, 
B. C. Head, about l|-4 in head. D. viii or ix-16 to 18 ; A. ii, 13; V. i, 1. Pectoral reaching 
anal or past vent even in largest specimens. Anal equidistant from tip of snout and base 
of caudal or nearer tip of snout. Ashy gray with blackish blotches. Nowell-defined crossbars 
except sometimes near the tail. Frequently a dusky blotch on anterior part of spinous dorsal 
and another near its posterior end; the fin sometimes wholly dusky, margined with white. 
Pectorals, soft dorsal, and caudal more or less barred. 
64. Cottus onychus Eigenmaun & Eigeumanu. 
Cottus oiit/cluis I^igenmann &. Eigenmann, Am. Nat., 963, 1892. Calgary. 
A single specimen 82 mm. long from Calgary. This species is evidently closely related to 
C. poUicaris (.1. & G.), from which it differs chiefly iu having manj’ prickles. Head, 3f ; depth, 
51; D. VIII, 17; A. 13; veutrals, i, 4; pectorals, 13. Teeth on vomer, none on palatin.es. 
Width of head equals its length to end of preopercular spine, its depth 2 in its length. Pre- 
operclo with an upturned claw-like spine, below which are two others, much smaller, the 
anterior one having its point turned downward and forward. Eye 1^ in snout, 1 in inter- 
orbital, 5 in head. Maxillary not reaching orbit. Sides above the lateral line, which is 
complete, with stiff prickles from below first spine to below the last dorsal ray ; prickles below 
the lateral line confined to the abdominal jiart of the sides. Dorsals connected by a low 
membrane, the rays much higher than the spines, 3| in head. Pectorals reaching past vent, 
its rays not branched. A dusky spot on breast just behind anterior end of .gill -slits; ventral 
surface, including the veutrals, otherwise jilaiu. Anal with a few dusky specks on its rays; 
other fins barred; sides and upper surfaces olive with darker spots. Three dark bands below 
soft dorsal; a dark baud just in front of the caudal. 
65. Lota lota maculosa (LeSueur). Winnipeg, Craig. Abundant at Winnijieg. A single specimen 
was taken in the Missouri with hook and line. This species was reported to me at Calgary, 
where it is said to ascend the streams south of Calgary iu great numbers. A species of 
“ling” was also reported to me at Golden* and again at Sicamous. From the descrijjtion 
given it must be closely related to the sj>ecies under consideration. It is said to reach a 
length of 1.50 m. At Sicamous they had this species for dinner just before I arrived, which 
is the nearest I came to securing it on the Pacific slope. 
* I have recently received a specimen from this place through Mr. Green. It is identical with the Atlantic slope form.
