y, we refer the specimens to _Scalopus
aquaticus australis_.

~Sorex cinereus cinereus~ Kerr

In his revision of the American long-tailed shrews, Jackson (N. Amer.
Fauna, 51, vi + 238, 13 pls., 24 figs., July 24, 1928) referred
specimens of _Sorex cinereus_ from Tyonek, Cook Inlet, Alaska, to the
subspecies _S. c. cinereus_ (_op. cit._: 46) and one specimen from
Chester Creek, Anchorage, Alaska, to the subspecies _S. c. hollisteri_
(_op. cit._: 56). Thus, the geographic ranges of the two subspecies
would seem to overlap around the northern shores of Cook Inlet. In an
attempt to resolve this seemingly anomalous distribution, we have
examined pertinent materials in the Biological Surveys Collection, U.S.
National Museum. We agree with Jackson (_op. cit._) that the series of
specimens from Tyonek is readily referable to _S. c. cinereus_. To our
eye, however, the specimen, No. 232691, from Anchorage is referable to
_Sorex cinereus cinereus_, rather than to _S. c. hollisteri_. The
reference is made on the basis of the darker color, especially of the
underparts. In this specimen, other characters that distinguish the two
mentioned subspecies are not apparent, probably because it is
relatively young; the teeth show only slight wear.

~Sorex trowbridgii humboldtensis~ Jackson

In his account of the long-tailed shrews, Jackson (N. Amer. Fauna,
51:98, July 24, 1928) listed under specimens examined of _Sorex
trowbridgii montereyensis_ four specimens from 7 mi. N Hardy, Mendocino
Co., California. Under his account of the subspecies _S. t. humboldtensis_,
however, he (_op. cit._:97) mentions that specimens (seemingly the same
four) from 7 mi. N Hardy "have shorter tails than typical representatives
of _humboldtensis_, but in color and cranial characters they are similar
to this [_humboltensis_] subspecies." We conclude, therefore, that the
specimens mentioned were inadvertently listed as _S. t. montereyensis_
and are _Sorex trowbridgii humboldtensis_. This conclusion is supported
by the fact that the locality concerned, 7 mi. N Hardy, is within the
geographic range assigned to _S. t. humboldtensis_ by Jackson (_op.
cit._:97); his southern records of occurrence of _S. t. humboldtensis_
are Sherwood and Mendocino, both in Mendocino County, California. Our
conclusion is further supported by Grinnell's (Univ. California Publ.
Zool., 40(2):80, September 26, 1933) statement of the range of _S. t.
montereyensis_ as "from southern M
