Utah, 35 (no. 26):26, June 30, 1945. _Dipodomys ordii longipes_, Stanford, Journ. Mamm., 12:360, November, 1931 (part--the part from King's Ranch, Utah). _Type._--Female, adult, no. 4612, Museum of Zoology, University of Utah; 1-1/2 mi. N Price, 5567 ft., Carbon County, Utah; obtained on June 5, 1940, by Ross Hardy and H. Higgins, original no. 1901. _Range._--East-central Utah, east into west-central Colorado. Marginal occurrences are: in Utah, 12 mi. E Price, 1-1/2 mi. N Price, Notom, King's Ranch, 12 mi. SW Green River, 16 mi. NW Moab; in Colorado, State Line and Grand Junction. _Diagnosis._--Size large (see measurements). Color dark, entire dorsal surface Cinnamon-Buff, purest on sides and flanks with but slight suffusion of black on upper parts; cheeks white; arietiform markings, pinnae of ears, plantar surfaces of hind feet, dorsal and ventral stripes of tail, brownish-black. Skull large; pterygoid fossae ovoid; lacrimal processes small; width across maxillary arches relatively great; auditory bullae well inflated; diastema short. _Comparisons._--From _Dipodomys ordii longipes_, _D. o. sanrafaeli_ differs as follows: Size smaller; color lighter, more cinnamon, pinnae of ears lighter; skull smaller; auditory bullae smaller; pterygoid fossae ovoid rather than round; wider across occipital condyles; narrower across zygomatic processes of maxillae. From _Dipodomys ordii cupidineus_, _D. o. sanrafaeli_ can be recognized by its larger size, lighter color and larger skull. For comparisons with _Dipodomys ordii nexilis_, _Dipodomys ordii priscus_ and _Dipodomys ordii uintensis_ see accounts of those subspecies. _Remarks._--Intergradation between _Dipodomys ordii cupidineus_ and _D. o. sanrafaeli_ is noted in the intermediate size of body in a single specimen from Notom. Intergradation in color and cranial characters occurs between _Dipodomys ordii nexilis_ and _D. o. sanrafaeli_ in specimens from 16 miles northwest of Moab. All these specimens, however, are referable to _D. o. sanrafaeli_.
