A New Pinon Mouse (Peromyscus truei) from
Durango, Mexico

BY

ROBERT B. FINLEY, JR.

The extensive collection of Mexican mammals made by Mr. J. R.
Alcorn for the University of Kansas Museum of Natural History
contains fourteen pinon mice from lava rocks eight miles northeast
of the city of Durango, Mexico. These mice are all much darker
than the pinon mice, _Peromyscus truei gentilis_, of adjoining areas
in Durango and Zacatecas and show a superficial resemblance to
the widespread _P. t. gratus_ which occurs 450 miles to the southeast.
Morphological differences from _P. t. gratus_, as well as geographic
considerations (see remarks), make desirable the recognition of the
lava-dwelling pinon mice from Durango as a distinct subspecies.

All specimens examined of subspecies compared with the series
of pinon mice from northeast of Durango are in the University of
Kansas Museum of Natural History. Capitalized color names and
designators are of Maerz and Paul, A Dictionary of Color, McGraw
Hill Book Co., New York, 1930.
