Descrihcfl Ami. ^Jt Mag. Nat. Hist. (8) viii. p. 700, 

 December 1911. 



At Mr. Carrutliers's suggestion this distinct Pika has been 

 named in honour of his comi)aniou Mr. ]\I. P. Price. 



45. Ochotona I^Ogotoma) hamica, sp. n. 



c?. 242, 243, 244. ? .^ 2.'^9, 240, 241. ^ N. Ilami Mts., 

 eastcrji end of Tliian Shan range, Cliinese Turkestan. 

 7500'. 



8ize as in 0. paUasi. General colour above of head and 

 body uniform pale drab, decidedly jialcr than liidg\vay^s 

 " diab," but not quite ids " ecru-drab." Under surface 

 broadly washed with paler drab, more or less tinged on neck 

 and middle line of chest with bufFy. Ears drab, a tuft at 

 their notch whitish drab; their proectote brownish, rest o£ 

 ectole slaty greyish ; entote drab, with a brown line passing 

 along parallel to the edges, which latter are whitisli. An 

 indistinct cream-buft' patch behind each ear. Rump tinged 

 with pinkish bufl'. Hands and feet cream-buff, tending 

 towards pinkish buff on the centre of the metapodials. 



Skull very similar to that of 0. pallasi, but the posterior 

 nasal region is broader, the nasals being more parallel-sided, 

 the interorbital region is not so remarkably constricted, the 

 palatal bridge is narrower, and the bulla; are larger. Tiie 

 auditory meatus is also larger ; but the type oi pallasi is not 

 quite perfect in this respect, so that the difference, if any, 

 cannot be judged with accuracy. 



Dimensions of the type (measured in flesh) : — 



Head and body 179 mm.; hind foot 33 (range 32'5-34) ; 

 ear 23. 



Skull: occipito-nasal length 50"5; condylo-incisive length 

 47'3; zygomatic breadth 25; nasals 16*7; least breadth between 

 anteorbital foramina across back of nasals 7'2 ; interorbital 

 constriction 4*1; parietal breadth 20*2; greatest posterior 

 breadth, on tympanies 25"5 ; palatilar length 19'2 ; palatal 

 foramina 9 ; breadth of palatal bridge 1*8 ; upper cheek- 

 tooth series (alveoli) 9*9. 



Ilah. as above. 



Type. Adult male. B.M. no. 12. 4. 1. 163. Original 

 number 243. Collected 5th Apiil, 1911. 



In this animal, of which Mr. Carruthers has sent an 

 excellent and remarkably uniform series, it is almost possible 

 to identify the Ochotona pallasi. Gray [Lagomys ogotoma, 

 Waterh.), which, based on JB.M. no. 45. 4. 21. 5, still remains 

 a stumbling-block to the worker in this group, owing to its 

 having no exact locality.
