_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_. =Sorex obscurus= Merriam Dusky shrew _Description._--The dusky shrew is similar in form of body to the cinereous shrew. The length of head and body is about 2-1/4 inches. The tail is about 2-1/2 inches. The upper parts are rusty or reddish brown. The underparts are brownish gray. The dusky shrew differs from the wandering shrew in possessing a slightly longer body and longer tail, but in eastern Washington the two species are almost indistinguishable. Dusky shrews range from northern Alaska to southern New Mexico, and from the Rocky Mountains to the Pacific Ocean. Thirteen subspecies are recognized by Jackson (1928: 115), of which two occur in Washington. Records of the dusky shrew are not available from the arid subdivision of the Transition or the Upper Sonoran life-zones. It occurs sparingly in the humid subdivision of the Transition and is common in the Canadian and Hudsonian life-zones. The habitat of the dusky shrew is varied. Near Seattle, King County, several specimens were trapped in marshes where _Sorex vagrans_ was abundant. Near Stevens Pass, King County, two were taken in a marsh; two others were trapped in a dry, coniferous forest; one was taken in a small bed of heather on a barren mountain top; and another was found dead in a pan of pancake batter in camp. Two specimens were trapped along a small stream at Dewey Lake, Mt. Rainier, Yakima County. Four specimens were caught in traps set in a talus slope on a dry hillside at the North Fork of the Quinault River, Jefferson County. Three others were trapped in dense, rain-forest thickets along the ocean at La Push, Jefferson County. These records indicate that the dusky shrew has a wider environmental range than other Washington shrews. Despite this wide range of tolerance the dusky shrew is common only locally, except in the Hudsonian Life-zone.
