This subspecies can be distinguished from _Dipodomys ordii fetosus_, _Dipodomys ordii celeripes_ and _Dipodomys ordii cupidineus_ by its darker color and generally larger size. For comparisons with _Dipodomys ordii cinderensis_ and _Dipodomys ordii fremonti_ see accounts of those subspecies. _Remarks._--This geographic race inhabits the upper reaches of the Sevier River Valley in the vicinity of Panguitch, Utah. Natural barriers to kangaroo rats, such as the Cedar Mountains to the west, high plateau country to the south, the Paunsaugunt Plateau to the east and the narrow canyons of the Sevier River to the north prevent these animals from extending their range or from coming into physical contact with any adjacent geographic races. This isolation has resulted in a fairly stable population. Some animals, however, show characters, such as the width of the rostrum, and the shape and length of the nasals which are intermediate between those of topotypes of _D. o. utahensis_ and the type series of _D. o. panguitchensis_. _Specimens examined._--Total, 3, all from Utah, distributed as follows: _Garfield County_: 1 mi. S Panguitch, 6666 ft., 3 (2 RH; 1 UU). =Dipodomys ordii monoensis= (Grinnell) _Perodipus monoensis_ Grinnell, Univ. California Publ.
