Sorex longirostris BACHMAN. Type locality Swamps of Santee River, South Caro-

The Field Museum collection contains 7 specimens of the Carolina 

 Shrew from extreme southern Illinois; 4 from Reevesville, Johnson Co., 

 and 3 from Olive Branch, Alexander Co. Aside from these the only 

 other specimen known to have been taken within our limits is that 

 recorded by Wood, as identified by Merriam, which was caught in a 

 tamarack swamp near Pistakee Bay, McHenry Co., November 14, 1907 

 (Wood. /. c., p. 582). 



The limits of its range are unknown, but it may be expected to occur 

 throughout Illinois and perhaps in southern Wisconsin. 



Its habits may be assumed to differ but little from those of S. per- 

 sonatus. 



Specimens examined from Illinois:
