_Sorex obscurus permiliensis_ Jackson, Proc. Biol. Soc. Washington, 31:128, November 29, 1918.
_Type._--Adult male, skin and skull; No. 91048, U. S. Biol. Surv. Coll.; obtained on October 2, 1897, by J. A. Loring from Permilia Lake, W base Mt. Jefferson, Cascade Range, Marion Co., Oregon.
_Range._--The Cascade Mountains of Oregon from Mt. Jefferson north to the Columbia River.
_Diagnosis._--Size medium for the species; average and extreme measurements of 14 specimens from the type locality are: total length, 117.7 (110-124); tail, 51.9 (45-58); hind foot, 14.0 (14-15). Pale reddish in summer, darker and brownish in winter.
_Comparisons._--For comparison with _S. v. bairdi_ see account of that subspecies. Larger than _S. v. setosus_ except tail relatively shorter. More reddish in summer pelage than _setosus_.
_Remarks._--_S. v. bairdi_ is larger in the southern part of its range than elsewhere. Specimens from McKenzie Bridge, herein referred to _yaquinae_, are intermediate in character between _yaquinae_ and _bairdi_ or between _yaquinae_ and _permiliensis_. The transition between _yaquinae_ and _bairdi_ is much more gradual than between _yaquinae_ and _permiliensis_.
