Four New Pocket Gophers
of the Genus Cratogeomys from Jalisco, Mexico

By
ROBERT J. RUSSELL

In the course of my taxonomic study of the genus Cratogeomys, a high degree of variation was found between several populations of these gophers in central Jalisco. Two species, C. gymnurus and C. zinseri, occur in this part of the state. Previously C. gymnurus was known only from southern Jalisco and C. zinseri only from extreme eastern Jalisco, but through the efforts of J. R. Alcorn specimens were obtained of both species in the central part of the state. These large gophers are difficult to collect, and I am grateful to him for securing this significant material. Costs of the field work were defrayed by the National Science Foundation and the Kansas University Endowment Association. Thanks are due also to those in charge of the United States Biological Surveys Collection for the loan of comparative material. Study of the recently acquired specimens taken in central Jalisco reveals two undescribed subspecies each of C. gymnurus and C. zinseri. These may be known and described as
