_Specimens examined._--Total, 7, all from the type locality and all in
the Biological Surveys Collection in the United States National
Museum.

Grateful acknowledgment is made of the opportunity to study the
specimens from New Mexico and Arizona in the Biological Surveys
Collection of the United States National Museum and the material from
South Dakota in the University of Michigan Museum of Zoology, as well
as for the financial support afforded one of us (Cockrum) by the
University of Kansas from its Research appropriation. Cockrum's work
was part of a larger investigation of the geographic distribution of
all North American native mammals, aided by a contract between the
Office of Naval Research, Department of the Navy, and the University
of Kansas (NR. 161-791). Also, assistance with some of field work was
given by the Kansas University Endowment Association.
