Both nongeographic and geographic variation was assessed in southern banner-tailed kangaroo rats of the nominal species Dipodomys phillipsii and D. ornatus . Univariate and multivariate analyses were employed in consideration of geographic variation. D. ornatus is arranged as a subspecies of D. phillipsii, in which four races (phillipsii, ornatus, perotensis, and oaxacae) are recognized. Some observations on natural history also are included.
