ing near (16" _j_) Snuff Brown as opposed to near (16' _i_) Buckthorn
Brown. Previous to the taking of this specimen, Webb and Jones
(1952:277) reported as _E. f. pallidus_ a specimen, saved as a skull
only, which was picked up dead at Niobrara. It seems best to assign
these two bats from the vicinity of Niobrara, Knox County, to _E. f.
fuscus_.

=Sciurus carolinensis carolinensis= Gmelin. GRAY SQUIRREL.--An adult
male gray squirrel shot by Mr. Terry A. Vaughan in the heavily timbered
bluffs of the Missouri River, 3 mi. S, 2 mi. E of Nebraska City, Otoe
County, on October 10, 1953, provides the only museum specimen of a
gray squirrel from Nebraska known to me. Residents in the area
concerned report small numbers of this squirrel as still occurring on
the heavily wooded bluffs along the Missouri River in Nemaha, Otoe and
Richardson counties, Nebraska, at least as far north as Nebraska City.

Gray squirrels from Nebraska have been reported twice before in the
literature as follows: "Mouth of Platte [River]" (Baird, 1858:262) and
Barada, Richardson County (Jones and Webb, 1949:312). Swenk (1908:80),
while listing no actual records, says of this squirrel, "Common in the
timber along watercourses of southeastern Nebraska, but greatly
outnumbered everywhere by [_Sciurus niger_] _rufiventer_. I have no
records west of the 97th meridian nor north of the Platte."

=Spermophilus franklinii= (Sabine). FRANKLIN GROUND SQUIRREL.--A
specimen from 2 mi. NW of Lisco, in Morrill County (NSM 3324), extends
the known geographic range of _S. franklinii_ approximately 200 miles
westward along the Platte River Valley from Kearney, Buffalo County
(see Howell, 1938:134), and suggests a westward movement of this ground
squirrel along the Platte River in recent years.

=Perognathus flavescens flavescens= Merriam. PLAINS POCKET MOUSE.--_P.
f. flavescens_ occurs in the Sand Hills and adjacent mixed-grass plains
of central Nebraska. Eastern marginal records of occurrence are:
Neligh, Antelope County, 2 (MVZ 1, NSM 1); 1 mi. E of Ravenna, Buffalo
County, 2 (MZ); unspecified locality in Adams County, 1 (HM).

=Perognathus flavescens perniger= Osgood. PLAINS POCKET MOUSE.--This
mouse occurs in northeastern Nebraska. Osgood (1904:127), in the
original description of the subspecies, listed two specimens from
Verdigris [Verdigre], Knox County. Additional records of occurrence
are: Beemer, Cuming County, 2 (USBS); 1-1/2 mi. SE of Niobrara, Knox
