_Diagnosis._--Size small (see measurements). Color pale, entire dorsal surface Pinkish Buff, purest on sides, flanks and cheeks, with but slight suffusion of black in upper parts; pinnae of ears, plantar surfaces of hind feet, dorsal and ventral stripes of tail, brownish. Skull small; rostrum relatively short and wide; nasals relatively short; lacrimal processes small; braincase but slightly vaulted; auditory bullae but little inflated; interorbital region narrow; styloid processes project on ventral surface of auditory bullae beyond middle of external auditory meatus; zygomatic arches robust and bowed laterally; pterygoid fossae ovoid. _Comparisons._--From _Dipodomys ordii marshalli_, _D. o. celeripes_ differs as follows: Size smaller, hind foot longer, tail shorter; color lighter; skull smaller; rostrum wider and shorter; interorbital region narrower; auditory bullae less inflated; lacrimal processes smaller; palate shorter; pterygoid fossae larger. From _Dipodomys ordii cinderensis_, _D. o. celeripes_ differs as follows: Size smaller, tail shorter; color lighter; rostrum wider and shorter; nasals shorter; interorbital width less; auditory bullae less inflated; foramen magnum wider and shorter; pterygoid fossae more circular. From _Dipodomys ordii columbianus_, _D. o. celeripes_ differs in: Size smaller; color lighter; rostrum wider and shorter; interorbital width less; interparietal region wider; auditory bullae, generally, less inflated; upper incisors longer and more robust; pterygoid fossae larger. For comparisons with _Dipodomys ordii fetosus_, _Dipodomys ordii pallidus_ and _Dipodomys ordii panguitchensis_ see accounts of those subspecies. _Remarks._--It appears that wherever the range of _D. o. celeripes_ meets that of an adjoining race, intergradation occurs freely. Practically all of the Nevadan specimens referable to this subspecies are intergrades with _Dipodomys ordii columbianus_ in size and color. Specimens from west of Delta, Utah, are intermediate in size between _Dipodomys ordii pallidus_ and _D. o. celeripes_ but their cranial characters are more as in _D. o. celeripes_. Intergrades with _Dipodomys ordii utahensis_ are discussed under the account of that subspecies. The characters differentiating _D. o. celeripes_ from any contiguous subspecies are not present in every specimen even in the type series. _Specimens examined._-Total, 96, distributed as follows: =Nevada=: _Elko County_: 13 mi.
