Remarks.—This richly-colored coastal race barely enters Washington. It is abundant near Goldrun Pass and Tomyhoi Lake, Whatcom County, just south of the international boundary.

Eutamias ludibundus Hollister, Smithsonian Misc. Coll., 56 (no. 26):1, December 5, 1911.

Tamias amoenus ludibundus [Ellerman], Fam. and Genera of Living Rodents, British Mus. Nat. Hist., p. 432, June 8, 1940.
Type.—Obtained at Yellowhead Lake, 3,700 ft., British Columbia, by N. Hollister on August 29, 1911; type in United States National Museum.
Racial characters.—Moderate size, brownish rump, ochraceous sides.
Measurements.—Five males and 4 females from the higher parts of the Cascades average, respectively: total length 210, 217; length of tail 89, 90; hind foot 33, 33; ear 17.4, 16.7; weight 50, 59.7 grams.
Distribution.—The higher Cascade Mountains. Marginal records are: Barron ([Howell], 1929:75), Lyman Lake ([Howell], 1929:75), Cascade Tunnel (W. W. D.), Mt. Stuart (W. W. D.), Lake Kachees (W. W. D.), Boulder Cave (W. W. D.), and Mt. St. Helens ([Howell], 1929:75).
Remarks.—At the higher altitudes this race seems to be the equivalent of affinis. The latter race lives in relatively arid yellow pine forests and ludibundus occupies more moist and varied habitats higher in the mountains.
