Sorex vagrans bairdi Merriam
Sorex bairdi Merriam, N. Amer. Fauna, 10:77, December 31, 1895.
Sorex obscurus bairdi, Jackson, Proc. Biol. Soc. Washington, 31:127, November 29, 1918.
Type.—Adult female, skin and skull; No. 17414/24318, U. S. Biol. Surv. Coll.; obtained on August 2, 1889, by T. S. Palmer, from Astoria, Clatsop Co., Oregon.
Range.—Northwestern Oregon, south to Otis and east to Portland.
Diagnosis.—Size medium for the species; average and extreme external measurements of 6 specimens from the type locality are: total length, 126.3 (124-130); tail, 55.0 (52-57); hind foot, 15.0 (14-15). Color Fuscous to Sepia in summer, darker in winter, underparts buffy.
Comparisons.—For comparisons with yaquinae see account of that subspecies. More reddish and larger than permiliensis with which bairdi intergrades to the east; specimens from Portland show evidence of such intergradation. Some specimens from southern Tillamook County show an approach to yaquinae.
Remarks.—S. v. bairdi lives primarily in forests as do yaquinae and pacificus.
