FEB., 1912. MAMMALS OF ILLINOIS AND WISCONSIN CORY. 415 



Description Color of back noticeably different from the sides ; upper 

 parts very dark brown; sides of body fulvous brown; under parts 

 ashy plumbeous, more or less faintly washed with brownish; tail 

 dark brown above, paler brown on under surface, the end blackish; 

 3rd unicuspid tooth decidedly larger than the 4th. All unicuspid 

 teeth larger than in S. fumeus and brain-case and rostrum heavier. 



In summer a nearly concolor brown pelage occurs hardly dis- 

 tinguishable from the brown pelage of S. fumeus. 



Measurements Total length, about 4.50 in. (114 mm.) ; tail vertebrae, 

 i. 60 in. (41 mm.); hind foot, .56 in. (14 mm.). 



Richardson's Shrew probably occurs throughout Wisconsin, but it 

 is doubtful if its range extends quite so far south as Illinois. There 

 are specimens in the Field Museum from Solon Springs, Douglas Co. ; 

 Sayner and Conover, Vilas Co.; and Pelican Lake, Oneida Co.; Jackson 

 records 5 specimens taken southeast of Rhineland in Oneida Co. (/. c., 

 p. 30); Synder secured a specimen near Beaver Dam, Dodge Co. (/. c., 

 p. 123); and Mr. W. H. Osgood secured a specimen in brown pelage at 

 Pelican Lake, Oneida Co., on September 20, 1911, which agrees per- 

 fectly in coloration with brown specimens of S. fumeus. The fact 

 that so few specimens have been taken does not necessarily imply that 

 the animal is rare, as all collectors know Shrews are by no means easy 

 to trap and are scarcely ever seen unless found in some pit or well 

 into which they have fallen. 



Specimens examined from Wisconsin: 



Wisconsin Solon Springs, Douglas Co., 2; Pelican Lake, Oneida Co., 

 i ; Sayner, Vilas Co., i ; Conover, Vilas Co., i; (S. C.), Beaver Dam, 

 Dodge Co., 1 = 6.
