illow Canyon, 10,000 feet, base of Deseret Peak, Stansbury Mountains,
Tooele County. This specimen is noteworthy not only in that it extends
the known range of this kind of mammal 50 miles to the west in Utah,
but in that it is well within the basin of the ancient lake. The marmot
is common in the Wasatch Mountains on the eastern mainland of Lake
Bonneville, but to date has not been found on the Oquirrh Mountains
immediately to the west. The Oquirrh Mountains are interposed between
the Stansbury and Wasatch mountains. The presence of the marmot on the
Stansbury Mountains indicates that it probably occurs also on the
Oquirrh Mountains.

_=Citellus beldingi crebrus=_ Hall. Belding Ground Squirrel.--Durrant
(1952:113) had only two specimens of this ground squirrel from
Standrod, Boxelder County. Additional specimens have been obtained from
the following localities in northwestern Boxelder County: Grouse Creek,
Park Valley, Grouse Creek Mountains, 12 miles northwest of Grouse
Creek, and Goose Creek. _C. b. crebrus_ now is known to inhabit all the
major drainages of the Raft River, Goose Creek, and Grouse Creek
mountains. In addition to extending the known area of occurrence of
this animal in Utah, these specimens prove also that this species is
not restricted to the Snake River Drainage as Durrant (1952:113)
supposed, but occurs also in the Great Basin Drainage.

_=Citellus richardsonii elegans=_ (Kennicott). Richardson Ground
Squirrel.--Recently, Hansen (1953:132) reported on specimens of this
species from Rich and Summit counties. Additional specimens are now
available from Highway 165 [2 mi. E Summit--Daggett Co. Line], 2 miles
south of Utah-Wyoming State Line; 5 miles west of Manila, and one mile
northeast of Manila (Carnegie Museum). These localities are in Daggett
County. The occurrence of these ground squirrels in Rich, Summit and
Daggett counties suggests that they occur along the entire northern
piedmont of the Uinta Mountains.

_=Citellus lateralis trepidus=_ (Taylor). Golden-mantled Ground
Squirrel.--Durrant (1952:126) estimated that practically all of the
area in Utah that is within the Great Basin might be included in the
range of this subspecies. Actually, he had specimens from only the Raft
River Mountains in northwestern Boxelder County. He included sight
records from the Deep Creek Mountains and from the Oquirrh Mountains.
Subsequently two specimens, numbers 7469A and 7470A, were obtained from
the Deep C
