Cherchen

— This species-named by me after my travelling companion P. P. Teleschow, senior subaltern of the Trans-Baikalian Cossacks, who prepared the skins of all specimens obtained on my fourth journey, and actively cooperated in the general work of the expedition- frequents the mountainous border of Northern Tibet, in the region between the gorges of the Cherchen and Khoten, i.e., the newly discovered Russian range and that of Keria.
