1922] Swarth: Birds and Mammals of the Stikine Region 163 



of the coast of southeastern Alaska and the wolf of the adjoining in- 

 terior. In the light of our limited material, and with the lack of a 

 systematic revision of this group of mammals, it is safer to consider 

 them as all one form, to which the name Canis occidentalis Richardson 

 seems applicable. 



The material obtained by us in the Stikine region consists of the 

 following specimens: skulls and limb bones of two adults (nos. 31042, 

 3i043) taken at Iskut Summit, sixty miles southeast of Telegraph 

 Creek, the gift of an acquaintance at Telegraph Creek ; an adult male 

 (apparently not quite full grown), skin only (no. 31009), shot at 

 Sergief Island, July 20, 1919 ; and two young females (about half- 

 grown), skins and skulls (nos. 31010, 31011), taken at Sergief Island 

 on August 24 and August 25, 1919. 



Mustela cicognani richardsoni Bonaparte. Richardson Weasel 

 "Weasels undoubtedly occur throughout the region traversed, though 

 we ourselves did not see one during the summer. At a trapper's cabin 

 a few miles from Telegraph Creek a pile of desiccated weasel carcasses, 

 his catch of the previous winter, yielded a series of nineteen skulls 

 (nos. 31023-31041), with complete skeletons in most eases. These 

 skulls, in comparison with a series from the coast of southeastern 

 Alaska, exhibit the differences stated by Merriam (1896, pp. 11-13) 

 to distinguish the two subspecies, Mustela c. richardsoni of the interior 

 and M. c. aiascensis of the coast. The Telegraph Creek skulls, as is 

 claimed for richardsoni, are perceptibly narrower between. the orbits 

 and across the muzzle, and there is a slight difference in 'the shape of 

 the zygomatic arches in the two lots. 



Allen (1903, p. 563) has described Putorius microtis from Shesley, 

 British Columbia, near the headwaters of the Stikine, but our series 

 of skuUs from Telegraph Creek are evidently all of one species, Mustela 

 c. richardsoni. 



Mustela vison energumenos (Bangs). British Columbia Mink 

 One trapped at Doch-da-on Creek on July 19 (no. 31002), and a 



skeleton preserved that was picked up near Telegraph Creek (no. 



31022). The species occurs, probably in fair abundance, throughout 



the whole Stikine region. The one skin obtained is notably dark eol- 

 • ored as compared with specimens of Mustela v. nesolestes from certain 



islands of the Alexander Archipelago, and we were told that the mink
