MAMMALS FROM WESTERN" CllIN'A. 133 



near smoke-grey. Hau<ls and feet whitish, a little tlarkeniiig on 

 tlie luetattirsals. Tail long and slender, uniformly grey-brown 

 above, whitish below\ In the summer specimens the underside 

 of the tail is scarcely lighter than the upper. 



Skull quite like that of A". 7n.acrurus, except that the brain-case 

 is conspicuously lower, the height nearly a millimeti'e less, the 

 length and width being about the same. Teeth i-ather nu)re 

 heavily pigmented. 



Dimensions of the type, measured in the flesh : - 



Head and body 60 nun. ; tail 90; hind foot 16 ; ear 10-5. 



Skull : condylo-incisive length 17*8; condylo-basal length 17'2; 

 greatest breadth 9 ; height of l)i-ain-case fi'om biision 4*9 ; length 

 of upper tooth-series 7'4. 



Hah. of type as above ; specimens from Mt. Omi believed to be 

 tl)e same. 



Ti/jm. Adult female. B.M. No. 11.9.8.22. Original number 2673. 

 Collected 13 January, 1911. 



The specimens from Mt. Omi collected in August, 1910, afo 

 darker-coloured and their tails are scarcely lighter below, but 

 they agree with the Yuen-ching examples in all other characters, 

 and it seems probable that their diflei-enees are merely seasonal. 

 They were formerly identified by me with .V. viacrnrus of 

 Darjiling, their distinctive character, the much lower brain-case, 

 not l)ecomiiig evident until the arrival of the present additional 

 material. 



11. ClIODSIGOA HYPSTBIA de Wint. 



5. 2604, 2642. Wei-choe, on Si-ho River, W. Sze-clnvan. 

 590O'--70OO'. 



These Shrews, collected in mid-winter, bear the same relation in 

 colour to de Winton's ty])e that the winter specimens of Sori- 

 cnliis irene do to those which I consider to be summer skins of 

 the same animal, their grey being similarly paler and their tails 

 more whitish. The tyjie locality is by no means distant, nor is 

 that of Ch. berezotcskli, which, as previously stated, I believe to be 

 of the same species. 



The skulls of these specimens, however, being perfect, indicate 

 that the Chodsiyoa previously obtained by Mr. Anderson in 

 Chih-li, and assigned to Ch. hypslhla, must be separated speci- 

 fically. It may be called 



ChoUSIGOA LAR VARUM. 



Thos. Abstr. P. Z. S. 1911, p. 49 (Oct. 31). 



General characters of Ch. hr/psihia, brain-case narrower and less 

 flattened. 



Fur close and fine; hairs of back about 3*8 nnn. in length. 

 General colour above "mouse-grey," rather lighter, apparently 

 ''smoke-grey" below. Hands and feet wliiti.sli. Tail brown 

 alcove, dull whitish brown below.
