, elevation 2600 ft., mile 742 (10 miles S and 50 miles E Teslin,
Yukon Territory), British Columbia, seem typical of _M. l. lucifugus_.
These were obtained on August 11, 1951, at the same locality where on
July 1, 1947, a single bat assigned to _M. l. alascensis_ Miller was
taken (see Baker, _op. cit._:95). The latter specimen is readily
distinguished by its darker color both above and below from those taken
in 1951.

=_Tamiasciurus hudsonicus kenaiensis_= Howell. Red Squirrel.--A female
taken at Peters Creek, elevation 300 ft., 20 miles NE of Anchorage, is
referred to this subspecies after comparison with the published
description of _T. h. kenaiensis_ Howell (Proc. Biol. Soc. Washington,
49:136, 1936), with specimens of _T. h. preblei_ Howell from Yerrick
Creek, Alaska, and with _T. h. petulans_ (Osgood) from 1 mile S of
Haines.

=_Tamiasciurus hudsonicus petulans_= (Osgood). Red Squirrel.--Three
specimens were taken on Chilkat Peninsula, elevation 10 ft., 7 miles SSE
of Haines, Alaska, and one at the southeast end of Sullivan Island.
These squirrels, taken in June and July, are molting on the sides, back
and rump. Compared with the specimens from the mainland the male from
Sullivan Island is paler on the back--near (_h_) Ochraceous-Tawny
instead of near (14_j_) Sudan Brown (capitalized color terms from
Ridgway, Color Standards and Color Nomenclature, Washington, D. C.,
1912)--and paler on the tail; otherwise this specimen resembles those
from the mainland.

=_Peromyscus maniculatus algidus_= Osgood. Deer Mouse.--Osgood (N. Amer.
Fauna, 28:54, 1909) reported intergradation between _P. m. algidus_ and
_P. m. hylaeus_ Osgood in the "region of Lynn Canal." One female from
the mouth of the Endicott River, elevation 10 ft., seems referable to
_algidus_. In comparison with two topotypes of _hylaeus_ this specimen
is not so dark and more nearly agrees with _algidus_ from the Chilkat
River, from 1 mile W of Haines and from Dezadeash Lake, Yukon Territory.

=_Phenacomys intermedius mackenzii_= Preble. Mountain Phenacomys.--An
adult female was taken on 28 July at the southwestern end of Dezadeash
Lake, elevation 2400 ft., in Yukon Territory (approximately 60 miles
from the Alaskan boundary north of the Lynn Canal), the same place where
a specimen was obtained in 1948 (see Baker, _op. cit._:104).

=_Microtus longicaudus littoralis_= Swarth. Long-tailed Vole.--Six of
these voles were taken on Sullivan Island (two at the nor
