Near M (E) melanogasler eleusis of Yunnan, but larger and with 

 smaller bullse. 



Colour of type as in eleusis, or slightly paler. Ears and feet as 

 in that animal. Tail rather longer. 



Skull larger and heavier than in eleusis ; interorbital region longer 

 and more parallel-sided. Palatal foramina narrowed in their pos- 

 terior third. Bullge decidedly smaller than in eleusis, an antero-pos- 

 terior diameter parallel with the middle line of the skull 6 instead 

 of 6.7mm. 



Teeth essentially similar to those of eleusis, and equally differing 

 from those of other forms by the more complicated m^ which has 

 four well developed salient angles on each side. But they are mar- 

 kedly larger. 



Dimensions of the type : — 



Head and body 108 ; tail 56 ; hindfoot 19 ; ear 15. 



Skull, greatest length 26.5 ; condylo-incisive length 26 ; zygo- 

 matic breadth 16 ; nasals' 8.1 ; interorbital breadth 4.7 ; palatal 

 foramina 5 ; upper molar series (crowns) 6.5.

Distinguishable by its larger size and smaller buUaB from M. m. 

 eleusis, the only form of the group which has the same complicated ia\ 



(23) Rhizomys wardt, sp. n. 



d 23, 25. 2 -26 (skull only) Imaw Bum, 9,000'— F. K.Ward. 

 Closely related to R. vestitus of Sze-chwan, but rather larger and 

 colour darker. 



Size distinctly greater than in vestitus, as indicated by the skull. 

 General colour as in that animal and similarly without the isolated 

 white hairs characteristic of E. senex and pruinosus ; but the tone 

 is darker owing to the tips of the hairs being sepia instead of " snufE
