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 vertebras, 

 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, i860, 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" (/. c, p. 60). 



The Common Shrew is found throughout Illinois and Wisconsin. 

 Kennicott reports it from Murphy sboro, Jackson County, in southern 

 Illinois, and states it is not uncommon in the northern part of the 

 state (/. c, 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
