Abstract
The subspecific status of various populations of the southern grasshopper mouse (Onychomys torridus) was examined using univariate and multivariate procedures. Sex, age and individual variation were assessed for the two populations with the largest sample sizes. Twenty four populations were analyzed for patterns of geographic variation corresponding to currently recognized subspecific boundaries of Onychomys torridus clarus, O. t. longicaudus, and O. t. pulcher.
