186 On Mammals from Mount [verest. 
habitual home at the highest altitude of any in the world. 
Although he did not bring any specimens from higher than 
17 500", Mr. Wollaston killed some at 20,100'—a_ height 
probably only rarely surpassed by wandering wolves, or, 
perhaps, Pantholops,—but as a habitual home this is probably 
the highest in existence. 
Incidentally we may note that a mouse (Phyllotis sublimis) 
was described by Thomas in 1900 from an altitude of 17,900! 
in Peru. 
It will be of interest, on the one hand, actually to have 
specimens from 20,000’, and, on the other, to find out how low 
it ranges, and whether it inter grades at all with the Nepalese 
form of O. royler, which was obtained by the Hxpedition at 
12,000’-13,000’ in the Kama Valley. 
“ We found this Pika from 14,500! to the snow-line; the 
highest seen were at 20,100', only i in mountainous and tae ky 
country.’—A. FR. W,

Tibet, 14,000’, 2nd-7th July, 
As very few examples of this Pika were in the Museum 
collection, the present series forms a valuable addition to the 
material for the study of the group. The majority of the 
specimens are in changing pelage, and three of them are 
young. 
“Between 14,000! and 15,000" on dry plains, where they 
burrow in soft ground.”—A, F. R. W.
