Intraspecific variation in external and cranial measurements of agile kangaroo rats (Dipodomys agilis) was evaluated using 3,078 adult specimens (1,694 males and 1,384 females). Males were larger than females for 17 of 19 characters examined, and significant geographic variation occurred in all characters for both sexes. Larger individuals were found in the northern and southern extremes of the species' range, and the smallest were in northern Baja California. Populations represented mostly by D. a. perplexus and D. a. fuscus tended to group separately from the others in some of the analyses, but no species-level differences were detected between populations.
