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 distinguisliing 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 j^ellow. 



Weasels are probably fairly abundant in the region, for, besides 

 those collected, others were seen at various times. On July 5 one wa* 

 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 iorealis and P. m. macrorMnus that neither name is
