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.
