Distribution.—This is the common marsh shrew of western Washington and occurs from the Pacific Ocean east to the Cascades at Lake Keechelus (W.S.M.) and 15 mi. NW White Salmon ([Jackson], 1928: 106).
Sorex vagrans monticola [Merriam]
Sorex monticolus [Merriam], N. Amer. Fauna, 3:43, September 11, 1896.
Sorex vagrans monticola [Merriam], N. Amer. Fauna, 10:69, December 31, 1895.
Type.—Obtained on San Francisco Mountain, 1150 ft. altitude, Coconino County, Arizona, by C. H. [Merriam] and V. [Bailey] on August 28, 1889; type in United States National Museum.
Racial characters.—Pale color.
Measurements.—Five males and 5 females from Selah, Yakima County, average, respectively: total length 100, 98.4; length of tail 40.6, 39.2; hind foot 12.2, 12.
Distribution.—Eastern Washington. The range of this shrew extends west to Bauerman Ridge ([Jackson], 1928: 113), Merritt (W.W.D.) and Maryhill (M.V.Z.).
Remarks.—A series of shrews from Moses Lake, Grant County, differs from monticola in larger size and darker color. They agree rather closely with Sorex r. amoenus from California and Nevada. Because they are isolated from that subspecies it seems best to consider them a microgeographic race referable to monticola.
