Fes., 1912. MamMats or ILLINoIs AND WISCONSIN — Cory. 215 
Measurements — Total length, about 6.50 in. (150 to 180 mm.); tail 
vertebrae, about 1.75 in. (45 mm.); hind foot, .88 in. (22 mm.). 
Habitat — Fields, meadows and swamps. 
The Meadow Mouse is common throughout northern Illinois and 
Wisconsin in low meadows, marshes, and wooded swamps; but it is 
also found in dry pastures and corn fields, especially in the autumn. 
Its exact southern range in Illinois has not been definitely determined 
but it probably does not extend much beyond the south central portion 
of the state. Wood records it from McLean Co., Illinois (/. ¢., p. 551). 
Coues mentions specimens from St. Louis, Missouri, and Hahn, from 
Munroe and Ohio counties, Indiana, which are the most southern 
records in the western portion of its range that I have been able to find. 
This Mouse is not uncommonly seen running about in the daytime 
and it is more diurnal in its habits than most of its kind. Two or three 
litters are born in a season and the young number from 5 to 8, generally 
sor 6. The nest is usually in burrows in tussocks of grass above the 
damp ground and is constructed of grass and pieces of weeds, the in- 
terior being lined with some soft substance, such as the pappus of milk- 
weed or cat-o’-nine-tails. The entrance is a hole on one side near the 
Meadow Mouse or Meadow Vole (Microtus pennsylvanicus).
