Type locality — Eastern United States. 
Distribution — Northern North America, from about the latitude of 
Virginia north to Hudson Bay and Alaska. 
Description — Upper parts approaching sepia brown (rarely. chestnut) ; 
under parts ashy gray or brownish ash; upper surface of tail and 
tip blackish; under surface of tail whitish; 3rd unicuspid tooth 
not smaller than the 4th. (See illustration, page 408.) 
Measurements — Total length, about 3.95 in. (100 mm.); tail vertebre, 
1.50 in. (38 mm.); hind foot, .50 in. (12.5 mm.). 
Remarks — The chestnut phase of pelage, which occasionally occurs, 
is apparently rare. There are two specimens in this Museum in 
brown pelage from Sumner, Wisconsin; one taken by L. Kumlien 
in May, 1860, and the other by T. Kumlien in June, 1880; the 
former was found impaled on a thorn by a shrike. According to 
Dr. Merriam, ‘‘Out of 20 specimens from Roan Mountain, North 
Carolina, only 2 are chestnut” (J. c., p. 60). 
The Common Shrew is found throughout Illinois and Wisconsin. 
Kennicott reports it from Murphysboro, Jackson County, in southern 
Illinois, and states it is not uncommon in the northern part of the 
state (J. ¢., p. 96). Wood reports specimens from McLean and Mc- 
Henry counties and there are specimens in the Field Museum from 
Lake County. 
Jackson considers it common in most parts of Wisconsin, as it 
doubtless is. I have examined specimens from various localities in
