A Pika allied to 0. dauurica, hut with lai-ger l^ullte. Size 

 rather larger than in 0. dcmurica. General colour above of 

 summer specimens pale wood-brown, tending to ochraceous-buffy 

 on the sides of the neck, the under surface approaching pinkish- 

 buff. Winter specimens rather paler and greyer. Patches behind 

 ears inconspicuous, ochraceous-buff ; ears with their proectote 

 black proxi mally paling to dull huffy terminally ; metentote huffy ; 

 lips and chin white, without darker markings. Hands and feet 

 creamy or huffy above, the long hairs of the palms and soles 

 whitish brown. 



Skull with the general characters of 0. dauurica, the type 

 of the subgenus Ochotona (see below), but larger, less strongly 

 convex on the forehead, with the brain-case larger, broader, and 

 running out to more definite postero-external angles, and the 

 buUce very markedly larger, perhaps the lai'gest in the genus. 

 Molars broader.

This Pika is very nearly allied to the Siberian and Mongolian 

 0. dauurica, which it closely resemliles in colour, but is dis- 

 tino-iiished by its luther larger size, much larger bullfe, and broader 

 molars. 



With regard to Ochotona huangensis Matsch., from Western 

 Kan-su, Prof. Matschie has been good enough to send me the 

 dimensions of its bulla^, and these appear closely to agree with 

 those of 0. daiturica, and are therefore markedly smaller than the 

 unusually large bullfe of 0. hedfordi. 



I have named this fine and distinct species in honour of His 

 Grace the Duke of Bedfoi'd, K.G., the importance of whose 

 assistance in the exploration of Eastern Asia is indicated by the
