montane mammals, will be found
throughout the entire length of the central mountain ranges.

_=Microtus pennsylvanicus modestus=_ (Baird). Pennsylvanian Meadow
Mouse.--In Utah this mouse was known only from wet meadows in valleys
immediately west of the Wasatch Mountains, as far south as a place 2
miles south of Provo (Hall and Cockrum, 1953:410). Norman V.
Chamberlain collected several specimens "near" Koosharem Reservoir,
Sevier County. These extend the known range of this subspecies 110
miles southward, and suggest that Pennsylvanian meadow mice occur, in
suitable habitat, all along the eastern margin of the Great Basin in
Utah, at least as far south as Sevier County. All northern specimens
are from the drainages of Utah Lake and Great Salt Lake, but these
specimens from Sevier County are from the Sevier River Drainage. This
species requires a fairly moist environment, and such habitat exists
between the aforementioned drainages which are practically
interconnected by Mona Reservoir and its adjacent areas of springs.

_=Zapus princeps utahensis=_ Hall. Big Jumping Mouse.--Durrant
(1952:388) reported a specimen from Puffer Lake, Beaver Mountains,
Beaver County. He supposed that this mouse occurred also at high
elevations still farther south in Utah. Subsequently, two specimens
were obtained from Garfield County; No. 9006 from Steep Creek, 12 miles
north of Boulder and No. 9071 from East Fork of Boulder Creek, 10 miles
north of Boulder. These two specimens extend the known range of jumping
mice in Utah 75 miles southeastward. Several specimens have been
obtained also from the Fishlake Plateau, and further bear out Durrant's
supposition that these mammals occur on all of the high mountains of
central Utah, at least as far south as the Aquarius Plateau.

_=Urocyon cinereoargenteus scottii=_ Mearns. Gray Fox.--One skull, No.
10,240, from mouth of Birch Creek, Deep Creek Mountains, Juab County,
extends the known geographic range 50 miles east from Cherry Creek
Canyon, Nevada (see Hall, 1946:241). This record indicates that the
species occurs in the mountainous areas on the western margins of
Pleistocene Lake Bonneville, and extends the known range in Utah
approximately 150 miles northward. Furthermore, this record proves that
the gray fox occurs as far north in western Utah as it does in eastern
Nevada, but to date none has been obtained from the mountains within
the basin of the ancient lake, even though some of them ar
