A. H. Howell (N. Amer. Fauna, 52:111, November 30, 1929) referred specimens of the Townsend Chipmunk from the lower elevations on the Olympic Peninsula to _Eutamias townsendii townsendii_ but referred specimens from the central mountains on that peninsula to _Eutamias townsendii cooperi_. The subspecies _T. t. cooperi_ thus is represented as having a geographic range of two separate parts: (1) The Cascade Mountains from southern British Columbia into southern Oregon, and (2) the area of the Olympic Mountains, the latter area being entirely surrounded by the geographic range of _T. t. townsendii_. Dalquest (Univ. Kansas Publ. Mus. Nat. Hist., 2:261 and 262, April 9, 1948) employed Howell's arrangement. We have examined the specimens, in the Biological Surveys Collection of the United States National Museum, from the Olympic Peninsula and fail to find significant differences in external measurements or in size or shape of skulls between specimens from the mountains (alleged _T. t. cooperi_) and those from other parts of the Peninsula (assigned to _T. t. townsendii_). Nevertheless, the specimens from the higher parts of the Olympic Mountains resemble _T. t. cooperi_ in being less ochraceous than are specimens of _T. t. townsendii_ from elsewhere on the Olympic Peninsula, and in this one respect, in series, they more closely resemble _T. t. cooperi_. Even so, the upper parts of the specimens from the mountains are darker than in _T. t. cooperi_ of the Cascades. In dark color of the superciliary stripe the specimens in question are referable to _T. t. townsendii_. The over-all gray tone, resembling that of _T. t. cooperi_, upon close inspection is found to be in considerable degree the result of wear, and the difference in grayness from _T. t. townsendii_, when specimens in comparable pelage are compared, is slight. This tendency to lighter color in specimens from higher elevations is seen in other places in Washington within the geographic range of _Tamias townsendii_. We feel, therefore, that the mentioned resemblance in color between specimens from the Olympic Mountains and those of _T. t. cooperi_ from the Cascade Mountains is not significant taxonomically. To us, all of the animals of the species _Tamias townsendii_ from the Olympic Peninsula seem best referred to the subspecies _Tamias townsendii townsendii_ Bachman. ~Tamias striatus ohionensis~ Bole and Moulthrop
