1S, pi. 18, figs. 5, 6. 

 Type locality. — Shoalwater Bay, Pacific Count}', Washington. 

 Coloration. — Above uniform Vandyke brown (darker, approaching bistre, 



in winter pelage) ; lower surface grayish brown approaching drab in 



tone; fur at base everywhere slate black; feet and tail dull drab above, 



slightly paler beneath. 

 Cranium. — In lateral outline high; braincase inflated, with height great 



in proportion to width. See figure 1 and table of cranial measurements. 

 Measurements. — Nine specimens, from Humboldt County, California,

 Areata, Perndale, and Cuddeback. Humboldt County; Novati 

 Point, Marin County. Merriam (1895, p. 68) records specimens 

 from Crescent City, Del Norte County ; Monterey, Monterey 

 County; and San Mateo, San Mateo County. The latter is a 

 Ideality close to the known range of the form here named »S'.

 belonged to this form.
