Bauer is situated in extreme western Tooele Valley at the foot of Stockton Bar, a low pass between the Stansbury and the Oquirrh mountains. This valley lies to the west of the aforementioned Jordan River. Although these gophers are definitely referable to _albicaudatus_ they are more unlike topotypes than are the animals from Riverton.
The specimens from Settlement Canyon, Oquirrh Mountains, Tooele County, show the same characteristics as those from Bauer.
In a large series of animals from St. John, in Rush Valley, Tooele County, the upper parts vary from black, even darker than topotypes of _albicaudatus_, to Tawny Olive, and the underparts vary from black through Cinnamon Buff to Pinkish Buff. Most of the animals are Cinnamon Buff. Although variable they approach _albicaudatus_ in color. The total length, tail and hind foot of males are longer than in topotypes of _albicaudatus_; females differ in the same direction but only slightly. In both sexes the zygomatic breadth is less, but the mastoid breadth is greater than in _albicaudatus_. In size and shape of the lacrimal processes, and the great thickening of the jugal at the maxillo-jugal suture they approach _robustus_. They are much larger, however, and in the majority of characters are referable to _albicaudatus_.
What has just been said relative to the animals from St. John applies also to those from Clover Creek in the Onaqui Mountains of Tooele County. At the latter locality the tendencies towards _robustus_ are accentuated. This is to be expected, since this locality is midway between St. John and the type locality of _robustus_. All characters considered, these animals are all referable to _albicaudatus_.
The animals from Little Valley, Sheeprock Mountains, Tooele County, resemble _albicaudatus_ in color. They vary on the upper parts from near (1) Sepia to Clay Color, and ventrally from nearly black to Pinkish Buff. They are markedly smaller in every measurement taken, except zygomatic and mastoidal breadths, and extension of premaxillae posterior to nasals. This relatively greater breadth indicates intergradation with _robustus_ to the west. These gophers are smaller in most measurements than any other population referred to _albicaudatus_. This is understandable because gophers from mountains usually are smaller and have weaker, smoother skulls than animals from low lands. Although approaching _robustus_ in size and in some aforementioned cranial details, the aggregate of characters including color, make these animals referable to _albicaudatus_.
