304 APPENDIX A 



Dimensions of the type (measured in flesh) :— 



Head and body 67 mm. ; tail 54 ; hind foot 13. 



Skull : condylo-basal length 18 ; condylo-incisive length 

 18*7 ; greatest breadth (c.) 9 ; upper tooth-series 80 ; com- 

 bined length oi p'^-m^ 4'7. 



Hah. and Type as above. 



The species of Chodsigoa are all very closely allied, 

 differing mainly by size and length of tail. This is the 

 smallest and shortest-tailed as yet described. 



6. Blarinella griselda, sp. n. 



?. 41. 42 miles S.E. of Tao-chou. 10,000'. 17th Sep- 

 tember, 1911. B.M. no. 12, 8. 5. 23. Type. 



" On mossy bank, in birch-wood."" — J. A. C. S. 



Smaller, greyer, and shorter-tailed than B. quadraticmtda. 



Size rather less than in quadraticmida. General colour 

 above " mouse-grey,*" rather paler and more drabby below. 

 Hands, feet, and tail all dull greyish, not dark brown as in 

 the allied species ; tail decidedly shorter than in that animal. 



Skull rather smaller than in quadraticmida. Second upper 

 unicuspid evenly intermediate in size between the first and 

 third — in q^iadratlcauda the second nearly equals the first 

 and is conspicuously larger than the third. 



Dimensions of the type (measured in flesh) : — 



Head and body 68 mm. ; tail 33 ; hind foot 1 1. 



Skull : condylo-incisive length 20 ; condylo-basal length 

 18*6 ; greatest breadth 9'4 ; upper tooth-series 8*6 ; front of 

 p^ to back of in? 4*5. 



Hah. and Type as above. 



This second species of the genus Blarinella is easily distin- 

 guishable from the Sze-chwan form by its smaller size, 

 greyer colour, and shorter tail. 



7. Mustela astuta^ M.-Edw. 



S. 40,73. 25 and 40 miles S.E. of Tao-chou. 9000-9500'. 



The marked narrowness of the frontal region distinguishes 

 this weasel from the Tibetan M. temon, Plodgs., which it 

 resembles very closely in external characters. The type was 

 obtained by David at Moupin.
