the axe sent it fluttering out, quickly to take refuge in a similar crevice
in a nearby tree. Small bats were seen occasionally up to August 21,
but not many and always late at night.

Mustela cicognani richardsoni Bonaparte. Richardson Weasel

Five specimens taken (nos. 32573-32577), four males and one
female, all from Kispiox Valley. These exhibit the cranial characters
of richardsoni, as contrasted with the subspecies alascensis of the coast
(see Merriam, 1896, p. 13). Besides skull variation, there are color
differences distinguishing the forms in the summer pelage. The five
Kispiox Valley specimens are of a dark, dull brown, close to raw
umber, the underparts almost pure white. The alascensis series at
hand (thirteen summer skins from the coast of southeastern Alaska),
are more reddish, the brightest colored specimens close to auburn, and
the underparts are often strongly tinged with yellow.

Weasels are probably fairly abundant in the region, for, besides
those collected, others were seen at various times. On July 5 one was
encountered in the daytime, carrying a freshly killed Drummond
meadow mouse. The weasel dropped his prey and escaped in the tall
grass ; the meadow mouse on examination was found to have the marks
of four tiny canine teeth, two in the base of the skull, above, and two
in the neck just below the skull. Weasels sometimes took mice from
our traps, and, acting on this hint, we were able to catch several in
steel traps baited with mice or birds.

Mustela vison energumenos (Bangs). British Columbia Mink

One specimen (no. 32578, adult male) collected in Kispiox Valley,
September 4. It is a dark-colored animal, similar to others at hand
from the lower Taku River and Wrangell, Alaska, the upper Stikine
River, and Seattle. (In this connection see Swarth, 1922, p. 163.)

Peromyscus maniculatus borealis Mearns.
Northern White-footed Mouse
Thirty-seven specimens collected near Hazelton (nos. 32579—
32615), twelve in Kispiox Valley (nos. 32616-32627), and ten on Nine-
mile Mountain (nos. 32628-32637).
The series as a whole is so nearly intermediate between Peromyscus
maniculatus borealis and P. m. macrorhinus that neither name is
