Musouin is less dark thau some of the Lord specimens. Unless the 

 exact locality were given, it is not improbable that some of Drum- 

 mond's specimens (if there were many) may have come from locali- 

 ties in the eastern Rockies, where that natnralist did most of his 

 collecting. In such a case the question would seem to be compli- 

 cated by specimens of origenes, which is almost undoubtedly the 

 race found on the headwaters of the Red Deer river in the Purcell 

 Range, where Drummond wintered. But the gist of the matter* 

 shorn of these complications, is Gray's desire to designate by name 

 a dark American marten found in the Rocky mountains by 

 Drummond. As no special type from a series of British Columbia 

 si^ecimens was designated by Gray, and as a special type or race 

 agreeing with his description has been found to live in the habitat 

 designated, it is within our province here to give it fixity by 

 restriction and elimination, rather than ignore or reject it as a 

 nomenclatural enigma. It may be added that an examination of 

 J. K. Lord's itinerary shows that it is very unlikely he secured any 

 specimens from the habitat of abietinoides as I have restricted it. 

 His operations with the Boundary Commission in the Rocky moun- 

 tains lay entirely south of the Selkirk and Gold Ranges. 



Measurements. — Made by collector from specimen No. 633, Coll. 

 of S. N. Rhoads, ?, Gold Range, near Vernon, B. C, by W. C. 

 Pound; taken November 22, 1892: Total length, 584 mm.; tail 

 vertebrae, 178 mm. ; hind foot (dry measurement), 87 mm. 

 Skull (of same specimen): Basilar length, 70 mm.; zygomatic 

 expansion, 43 mm.; postorbital constriction of frontals, 17 mm. 

 Measurements of the male, judging l)y analogy of the sexual differ- 

 ences in other races, would nearly e(iual those given for aduosa and 

 brumalis. 



Mustela atrata Bangs. Newfoundland Marten. 



1897. Mustela atrata Bangs, Americau Naturalist, Vol. 31, p. 1G2. 



Type Locality. — Bay St. George, Newfoundland. 



Faunal Distribution. — Newfoundland. 



Description of Species. — I have seen no specimens of this form, 

 which .seems nearly related in size and color, etc., to the dark mar- 

 lens of the northern Rocky mountains. As it is confined to the 

 island, it is considered by Mr. Bangs, its describer, as a distinct 

 species, on geographic rather thau anatomical grounds. Its affini-
