Kansas University Endowment Association. The loan of specimens for
comparative study from the Biological Surveys Collection of the United
States National Museum is acknowledged.

=_Sorex obscurus alascensis_= Merriam. Dusky Shrew.--Comparison of two
specimens from 7 miles SSE Haines and eight from Sullivan Island (six
from the northeast end of the island and two from the southeast end)
with topotypes of _Sorex obscurus longicauda_ Merriam from Wrangell,
Alaska, and with topotypes of _Sorex obscurus alascensis_ from Yakutat,
Alaska, shows that our specimens are intermediate between the two named
kinds. However in nine of ten characters these specimens more closely
resemble _S. o. alascensis_ than _S. o. longicauda_. Measurements of
specimens from Wrangell and from localities progressively northward
along the Alaskan coast reveal a decrease in size of the skull in a
clinal fashion. Specimens from Sullivan Island are larger than those
from the mainland south of Haines, which are in turn larger than
specimens from 9 miles W and 4 miles N of Haines (reported upon by
Baker, _op. cit._). No step is apparent in this cline and assignment of
specimens must be made on a somewhat arbitrary basis. Specimens from
Juneau, Alaska, in the Biological Surveys Collection of the United
States National Museum, were assigned by Jackson (N. Amer. Fauna, 51:
128, 1928) to _S. o. alascensis_ but seem to us to be closer to _S. o.
longicauda_.

=_Sorex palustris navigator_= (Baird). Water Shrew.--Two males taken on
August 5, at Peters Creek, elevation 300 ft., 20 miles NE of Anchorage
provide a northwestern extension of the known range of this species. In
external and cranial characters the males resemble _S. p. navigator_
from 9 miles W and 4 miles N of Haines, Alaska, and from Washington
County, Idaho. The specimens from Peters Creek do not agree with the
description of _Sorex alaskanus_ Merriam as given by Jackson (_op.
cit._:189) although one, a second year animal, has the lambdoidal crests
exceptionally well developed, as does _S. alaskanus_.

=_Myotis lucifugus lucifugus_= (LeConte). Little Brown Myotis.--A male
taken at Peters Creek, elevation 300 ft., 20 miles NE of Anchorage, is
darker than specimens assigned to this subspecies from northeastern
British Columbia (Muncho Lake). Eight skins and skulls (three adults and
five young of the year) and 18 specimens in alcohol taken at Screw
Creek
