The Western Cotton Mouse is not uncommon in southern Illinois. 
The Museum collection contains specimens from Ozark, Golconda, and 
Olive Branch, but thus far it has only been taken in the extreme south- 
ern portion of the state. Howell states that it is common in swamps 
and wooded bluffs of the Lower Austral Zone and that specimens were 
collected at Olive Branch, Wolf Lake and Golconda, Illinois, and also 
in Missouri. (J. c., p. 26.) Rhoads, who observed this Mouse in 
Tennessee, writes, ‘‘So far as I have made its acquaintance in Tennes- 
see, the Cane Mouse is solely a denizen of the ‘bottom lands’ of the 
Mississippi. At Samburg it confined its wanderings very closely to 
the immediate vicinity of Reelfoot Lake, and was abundant in the 
dense forest jungle that bordered its margin, seeming to prefer the 
lowest and wettest parts of the overflowed lands.” (J. ¢., p. 189.) 
Specimens examined from Illinois:
