noted that iu not one of the specimens are the two bridges over 

 the lateral grooves on the posterior palate complete, while they 

 appear to be always complete in ti'iie Evotomys. 



Teeth broad and powerful, their pattern much as in E. rufo- 

 canus ; last segment of m' simple, with scarcely any trace of ;i. 

 postero-internal re-enti-ant angle. 



Dimensions of the type, measured in the flesh : — 



Head and body 119 mm. ; tail 47 ; hind foot (s. u.) 20 ; ear 15. 



Skull — greatest length 27*8 ; basilar length 24 ; zygomatic 

 breadth 16 ; length of nasals 8 ; interorbital breadth 3"7 ; diastema 

 7'9 ; palatilar length 13; palatal foramina 5'7 ; length of upper 

 molar series 6-4 ; breadth of front lamina of m^ 1"3.

I have named this handsome Vole after Her Grace the Duchess 

 of Bedford, whose interest in zoology is not less than that of her 

 husband. 



E. hedfordicti agi-ees with the Scandinavian E. rufocanus, the 

 type of the subgenus Graseoinys, in all essential particulars, but 

 may be readily distinguished by its more glareoltis-Ysk^^ colour, less 

 contrasted back and sides, and longer, less hairy tail. 



E. (C) latastei Allen, from Kamtchatka, is a considerably 

 smaller animal. 



An example of this species was obtained by the late Dr. John 

 Anderson in Hokkaido in 1885, and presented by him to the 

 British Museum, but has not hitherto been identified.

Yery like E. {Craseomys) hedfordice externally, but with longer 

 tail, and the teeth miich less powerful. 



Genei'al external appearance almost exactly the same as in 

 E. hedfordice, the fur of the same long loose texture, and the 

 colour similarly dark lined chestnut passing gradually into 

 greyish on the sides, without the marked contrast found in 

 E. riffocanits. Undei' surface rather darker buff than in E. hed- 

 fordice. Feet rather shorter than in the allied species ; tail 

 longer, its dark upper less contrasted with its pale lower surface. 



Skull of the same general shape as in E. hedfordice, and with 

 the same long jjarallel-sided interorbital region, but more lightly 

 biiilt throughout. Palatal foramina shorter. Hinder edge of 

 palate with the bridges over the lateral grooves complete. 



Teeth conspicuously lighter and weaker than in E. hedfordice, 

 the incisors and all the molars much narrower. Pattern in a
