SINO-MONGOLIAN FRONTIER . 
human habitations, where it preys upon rats, 
mice and the occupants of the poultry yard. 
This mink has nothing to boast of in the 
way of fur, but skins are shipped in great 
numbers from North China to Europe under 
the name of weasel. 
The Chinese name, ‘Huang hsu_ lang,”’ 
means ‘ Yellow rat wolf.” 
7. Mustela sp. 
8. 
One skin from the Ning-wu district in 
West Shansi. 
A small musteline, closely resembling in 
colour the foregoing species, but having a 
much shorter tail. As yet this specimen 
cannot be identified. 
Mustela larvata, Hodgson. 
Three incomplete specimens (two skins 
and one skull). Wu-tsai, 20 miles W. of 
Ning-wu Fu, Shansi. 6,000 ft. (?) 
These specimens were indistinguishable 
from those secured in Kansu on the Clark 
Expedition, though the winter fur showed a 
distinct lightening in colour, one skin being 
almost white. So far, this species has not 
been discovered east of the Wu-tsai plain, 
though the natives of K’uei-hua-ch’éng, North 
Shansi, described an animal very similar to 
this polecat.
