older specimens from the same place
would be paler by a slight degree. This suspicion, and more especially
the light color of an older specimen from nearby White Salmon,
Washington, and the light color of two older specimens from Parkdale,
Oregon, which seem to us to be referable to _T. t. cooperi_, influence
us to refer the specimen from Hood River to _Tamias townsendii cooperi_
Baird.

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 t
