with rolled oats, peanuts, bacon, or fresh meat. Their stomachs gen- 

 erally show insect remains and their food habits are probably as 

 varied as those of other shrews. 



SOREX PACIFICUS YAQUINAE JACKSON 

 YAQUINA SHBEW 



Sorex yaquinae Jackson, Biol. Soc. Wash. Proc. 31 : 127, 1918. 



Type. Collected at Yaquina Bay, Lincoln County, Oreg., July 18, 1895, by 

 B. J. Bretherton. 



General characters. Slightly smaller than pacificus, colors slightly darker 

 brown, but general appearance much the same. 



Measurements. Type : Total length, 137 mm ; tail, 59 ; foot, 16. Adult male 

 from Philomath: 145; 60; 15. 



Distribution and habitat. Coast section of central Oregon (fig. 

 88). There are specimens from Yaquina Bay, Newport, Mercer, 

 Elk Head, Mapleton, Philomath, Eugene, and Yida, all in the low 

 humid Transition Zone. 



At Philomath Cantwell reports a pair of these large brown shrews 

 taken near a creek on low ground strewn with rotten logs. At 

 Mapleton, Luther Goldman found them along streams in timbered 

 canyons, and at Gardiner, McLellan caught one in a cool ravine 

 and another on the dyke along the river front. 



So far as our limited information goes there seems to be no 

 difference in the habits of yaquinae, pacificus, and ~bairdi from this 

 low, humid coast section of the State. 



SOREX VAGRANS VAGRANS BAIRD 

 VAGRANT SHREW 



Sorex vagrans Buird, Mamin. North Ainer., p. 15, 1857. 



Type. Collected at Shoalwater Bay, Pacific County, Wash., by J. G. Cooper; 

 date of collection unknown, but cataloged October 23, 1856. 



General characters. Very small, general appearance as in the obscurus 

 group. Color, upper parts tobacco brown in summer pelage with distinctly 

 grayish belly and bicolored tail. In winter pelage seal brown above and silvery 

 gray below, tail dark brown above and buffy below. 



Measurements. Average of typical adults : Total length, 104 mm ; tail, 42 ; 

 foot, 12. Adult female from Eugene, Oreg.: 102; 41; 12. Weight about 7 g. 



Distribution and habitat. Southwestern British Columbia, west- 

 ern Washington and Oregon and northwestern California, south 

 along the coast to Point Reyes. In Oregon they range east to the 

 Yamsay and Paulina Mountains, well beyond the east base of the 

 Cascades, but not across the sagebrush plains (fig. 89). Over much 

 of western Oregon these are the commonest small shrews and often 

 the commonest small mammal found in the woods, dry uplands, 

 meadows, and marshes. They occur mainly in Transition Zone, but 

 to some extent also in Canadian Zone. 



General habits. These little brown shrews are generally caught in 

 traps set under old logs, around loose rocks, or under the fallen grass 

 or other vegetation, which affords a shady cover and protection 

 from light and enemies. To some extent they burrow in the mellow 

 woods earth but more commonly push up little tunnels between the
