lus being silvery grey at base, buffy terminally. On the undersur- 

 face however the chest patch has a suffusion of bnffy, as in oiostolus, 

 the rest being pure white. Head grizzled black and pale buffy ; 

 eye-rings cream-buff. Ears essentially as in oiostolus, but the buff 

 replaced by grizzled blackish except along the terminal third of the 

 metentote, where there is a buffy edging ; fringe of proectote white. 

 As in oiostolus the rump is slaty grey and the tail thick, bushy, 

 wholly pure white except for an inconspicuous slaty line proximally 

 above. Hands buffy above, feet white, the cushions of both below 

 drabby.

T^/pe.— Immature male. B. M. No. 14. 6. 24. 3. Collected 12th 

 August. 191 3 and presented by Oapt. F. M. Bailey. 



The specimen appears unfortunately to be somewhat immature, 

 but examples of true oiostolus of similar age show the same strong 

 bufly colour that is characteristic of the adults. In general body 

 colour this new form somewhat more resembles the L. hozlovi of 

 still further Eastward, but that species has not the highly char- 

 acteristic white tail of L. oiostolus. 



Besides the above new forms Capt. Bailey obtained an example 

 of Nectogale sihhimensis, de Wint., from Karpo, Tibet, and one ol 

 Ochotona curzonice, Hodgs., from Nyerma La, 15,000',
