_nelsoni_ or _canescens_), nor between _P. intermedius_ and
_P. nelsoni_. Collecting and studying specimens from geographically
appropriate places to test for intergradation between these three
species would be worthwhile as a means of improving our knowledge of
the taxonomy of these mice.

We are obliged to J. R. Alcorn and William L. Cutter for
collecting many of the specimens used by us, to the Watkins
Fund of the Kansas University Endowment Association and to
the American Heart Fund for financial assistance with
collecting the specimens, to the National Science Foundation
for financial assistance with study of the specimens in the
Museum, to William H. Burt of the University of Michigan,
and to Stanley P. Young, Richard P. Manville and Viola S.
Schantz of the Biological Surveys Collection of the United
States Fish and Wildlife Service for lending certain
specimens.
