DESCRIPTION OF A NEW WEASEL FROM THE 
ROCKY MOUNTAINS OF BRILISH” COLUMBIA: 
BY OUTRAM BANGS. 
Putorius (Arctogale) longicauda oribasus* subsp. nov. 
Type, from source of Kettle River, British Columbia, altitude 7500 feet, 
Q old adult, no. 9058, coll. of E. A. and O. Bangs, collected Sept. 10, 1898, by 
Allan C. Brooks. 
Subspecific characters.— Size of true P. dongicauda of the Plains, differing 
from that form in being very much darker brown above. The upper parts are 
darker and more dusky than in P. longicauda spadix. From P. saturatus of 
the Cascade Mountains of British Columbia, the new form can be told by 
being paler yellow below, with under side of tail and anal region yellow (as in 
true P. longicauda), by lacking the brown spot at corner of mouth, by having 
white upper lips, and by the upper parts being more dusky and olivaceous — 
less reddish brown. 
Color.— Type, September: upper parts bistre, without reddish or chestnut 
shades, whole head, except ears, much darker, more dusky; upper lip and chin 
white; rest of under parts, including two thirds of lower surface of tail, inside 
of legs and under surface of arms, buff-yellow; tip of tail black; upper sur- 
faces of hands and toes soiled white. 
Cranial characters.— Skull much larger than that of P. arizonensis, about 
equal in size to that of large examples (of the same sex) of true P. Jongicauda. 
Compared with female skulls of P. lomgicauda, it is slightly shorter and 
broader; audital bulle wider and flatter; palatal extension shorter and wider. 
Measurements. — Type, 9 old adult: total length, 392.; tail vertebra, 150.; 
hind foot, 46. mm. 
1 6pe8aoos — mountain climber.
