_Felis oregonensis oregonensis_ Miller, U. S. Nat. Mus. Bull., 128:158, April 29, 1924. _Felis concolor oregonensis_ Nelson and Goldman, Jour. Mamm., 10:347, November 11, 1929. _Type locality._--"Oregon Mountains, or east or west of them." _Racial characters._--Light, rounded skull, dark color, extensive black on tip of tail and short, rather coarse fur. _Distribution._--From the eastern base of the Cascade Mountains westward to the Pacific. Marginal records are (trappers' specimens): Ruby, Leavenworth, and Goldendale. =Felis concolor missoulensis= Goldman _Felis concolor missoulensis_ Goldman, Jour. Mamm., 24:229, June 8, 1943. _Type._--Obtained 10 miles southwest of Missoula, Missoula County, Montana, by R. and C. Thompson, on December 30, 1936; type in United States National Museum. _Racial characters._--A large cougar with heavy, wide skull, pale color and rather long, soft fur. _Distribution._--Northeastern Washington west at least to Republic (W.W.D.) and the Blue Mountains of southeastern Washington. _Remarks._--Goldman (1943: 229) states "Between the Rocky Mountains and the Cascade Range _missoulensis_ intergrades with _oregonensis_." My own comparison of specimens reveals differences of considerable magnitude between the cougars of western and northeastern Washington. I suppose that intergradation takes place in a limited area in, and west of, the Okanogan River Valley in Washington. [Illustration: FIG. 75.
