ir, and 19 miles
west of Enterprise, Washington County; Bown's Reservoir, Snow Ranch,
Hall Ranch, Steep Creek, Garfield County; Aquarius Guard Station,
Aquarius Plateau, Wayne County. Insofar as we are aware, these
occurrences are the first to be recorded from Utah, and extend the
known range of this subspecies 150 miles northward.

The specimens from Washington County are paler than those from Garfield
County, and this pallor indicates intergradation with the subspecies
_P. p. olivaceus_. Of animals from the Aquarius Plateau, those from the
eastern and southern localities are pale and have a marked suffusion of
ochraceous in the upper parts, whereas those from the western and
northern localities are extremely dark owing to a heavy suffusion of
black in the upper parts. The skulls of animals from the Aquarius
Plateau resemble those of _P. p. trumbullensis_ in the majority of
diagnostic characters. In some few characters, nevertheless, the skulls
resemble those of _P. p. olivaceus_, and in other characters are
intermediate between these two named subspecies. In shape and size of
the interparietal, in slightly longer nasals, and in slightly greater
alveolar length of upper molariform teeth, animals from the Aquarius
Plateau differ from either of the aforementioned subspecies. All
characters considered, we deem it best to refer these specimens to the
subspecies _P. p. trumbullensis_.

_=Thomomys talpoides bridgeri=_ Merriam. Northern Pocket Gopher.--An
adult female, Catalogue No. 25667 of the Museum of Natural History of
the University of Kansas, skin with skull, was trapped, on 30 June
1948, 14 miles south and 2 miles east of Robertson, 9,300 feet, in
Summit County, Utah, by James O. Lonnquist (original number 146). This
is the first record of this subspecies from Utah, and raises to 37 the
named kinds of pocket gophers known from Utah.

_=Reithrodontomys megalotis megalotis=_ (Baird). Western Harvest
Mouse.--Durrant (1952:295) reported no harvest mice from the Uinta
Basin in northeastern Utah. One specimen, No. 10,239, was obtained from
two miles east of Duchesne, Duchesne County. This specimen extends the
known range in Utah 50 miles northward, and indicates that the harvest
mouse of the subspecies _R. m. megalotis_ occurs throughout the Uinta
Basin.

_=Onychomys leucogaster pallescens=_ Merriam. Northern Grasshopper
Mouse.--Hansen obtained specimens (in alcohol) from Kennedys Hole,
junction of the White and Green
