MAMMALS FROM CENTRAL CHINA. 689 



angle of the mouth, separated from its fellow of the opposite side 

 by a white interramial space over an inch broad. Light throat- 

 patch not really white, but bi-ownish white, figui-ed in leucolcenitts 

 as snowy white. Light patch in front of ear less prominent, 

 continuous with but darker than that under the eye. White 

 ear-rim much broadei' and more prominent. Back more broadly 

 washed with whitish than appeal's to be the case in leucolcenitcs, 

 the dorsal hairs white for their terminal 15-20 mm., while onl)^ 

 their points ai^e said to be white in leucolceynus. Tail wholly 

 white. 



Dimensions of the type, measured in the flesh : — 



Head and body 570 mm. ; tail 195 ; hind foot 94 ; ear 45. 



Skull: condylo-basal length 132 mm. ; basal length 123 ; greatest 

 breadth 72 ; intei'orbital breadth 29 ; palatal length 86 ; greatest 

 diameter of m^ 16. 



ffab. and t7/pe as above. 



The British Museum had previously possessed no examples of 

 the N. Chinese Arctonyx, so that this fine specimen is a valuable 

 accession. On account of the differences above detailed I cannot 

 refer it to the true leihcolmmus, but think it represents a special 

 subspecies, as is the case with so many other Shen-si mammals.

In my previous paper the Kan-su specimens of this group were 

 assigned to E. confucianus luticolor, though tending to intergrade 

 with the typical E. confucianus of Sze-chwan. But now, on 

 laying out the whole of the N. China representatives of the group, 



* Fetaurista is masculine, tliis being one of the numerous names which by their 

 deceptive form render desirable the suggested convention that all generic names in 

 zoology should be treated as masculine. See Stebbing, ' Knowledge,' xxxiii. p. 259, 

 1910.
