gophers in central Jalisco. Two species, _C. gymnurus_ and _C.
zinseri_, occur in this part of the state. Previously _C. gymnurus_ was

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. gymnu
