_Distribution of Peromyscus boylii in Kansas_

The subspecies _Peromyscus boylii attwateri_ is known in the state only
from Cherokee County, the southeasternmost county in the state. Probably
the only locality where the brush mouse occurs in that county is on the
systems of cliffs along Shoal Creek, southward from Galena, to the
eastward of Baxter Springs. This is the extent of the known range, and
in my opinion the probable range, of _P. b. attwateri_ in the state (see
Fig. 1). Cockrum (1952:fig. 49) by mistake mapped the species from west
of Baxter Springs in Cherokee County.

Osgood (1909:149) recorded the subspecies _P. b. attwateri_ from Cedar
Vale, Chautauqua County, Kansas, but the specimen from there must now be
assigned to _cansensis_ on geographic grounds. Probably the specimen was
