ICG ]Mr. 0. Thomas on a new 



slaty grey, scarcely paler than tlie upper surface. Upper 

 surface of hands and feet dull brownish grey, the darker 

 nietapodial markings present, but less defined than usual. 

 1'ail well- haired, brown above and at the end all round, 

 sharply defined white below for its proximal two thirds. 



Skull and teeth apparently quite of the usual proportions, 

 the different species seeming to differ from each other only in 

 size. 



Dimensions of the type (measured in skin) : — 



Head and body (stretched) 120 millim. ; tail 92 ; hind foot 

 (s. u.) (wet) 23-2. 



Skull : greatest length 2-i ; basal length 22 ; interorbital 

 breadth 5*7 ; length of ujjper tooth-row 11'2 ; combined 

 length of;/ and three molars 6'5 ; lower tooth-row from tip 

 of incisors lO'-i. 



Hah. Kuatun, N.W. Fokien. Altitude 1200 m. 



Type. B.M. no. 2. 6. 10. 3. Presented by F. AV. Styan, 

 Esq. "Winter." 



This species is most nearly allied to the Himalayan G. hima- 

 lai'ca, but differs by its smaller size, smaller teeth, paler 

 general colour, darker belly, and the non-extension of the 

 white of the underside of the tail to the end. The Japanese 

 C. pJatycephcda is much larger, the beautiful Sze-chuen 

 C. Styani is smaller, with a strongly contrasted light under- 

 side, and the Bornean C, phceura is darker throughout, with 

 a wholly brown tail. Although- undoubtedly all very closely 

 allied to each other, the different species seem to be readily 

 separable by these characters of size and colour. 



XXV. — A new Vole from the Lower Yang-tse-hiang. 

 By Oldfield Thomas. 



The only Vole hitherto known from the Oriental part of 

 China has been the peculiar Mtcrotus (Eothenomys) melano- 

 gaster, M.-Edw., found in the mountains of N.W. Fokien, 

 and it has therefore been with much interest that I have 

 examined a series of a species found by Mr. E. B. Howell 

 near Nanking, on the Lower Yang-tse-kiang, the river 

 usually considered as the dividing-line between Paljearctic 

 and Oriental China. 



The species proves to be of considerable interest from its 

 combination of characters, as will be seen below.
