Kangaroo Rats (Biological Monograph)

Twenty morpholoigcl characters in addition to color were studied throughout the geographic range of two species of kangaroo rats, the banner-tailed kangaroo rat Dipodomys spectabilis and the desert kangaroo rat Dipodomys deserti. A total of 2725 specimens from 689 localities was examined in this study: 1,187 specimens from 368 localities for D. spectabilis and 1,538 specimens from 321 localities for D. deserti. The two species are characterized and notes are given concerning their habitat, longevity, predators, parasites, molt, and reproductive activity.
