Show 354 Mil. OLDFIELD THOMAS ON [Nov. 28, noted that in not one of the specimens are the two bridges o\ er the lateral grooves on the posterior palate complete, while they appear to be always complete in true Evotomys. Teeth broad and powerful, their pattern much as in E. rufo-canus; last segment of m3 simple, with scarcely any trace of a postero-internal re-entrant 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 m2 1'3. Hab. Hokkaido. Type from Shinshinotsu. Type. Adult male. B.M. No. 6.1.4.298. Original number 23. Collected 10 September, 1904. 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. bedfordice agrees with the Scandinavian E. rufocanus, the type of the subgenus Craseomys, in all essential particulars, but may be readily distinguished by its more glareolus-like 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. 3 7 .

Makado, near Nohechi, Aomori Ken, extreme North Hondo. Very like E. (Craseomys) bedfordice externally, but with longer tail, and the teeth much less powerful. General external appearance almost exactly the same as in E. bedfordice, 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. rufocanus. Under surface rather darker buff than in E. bedfordice. 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. bedfordice, and with the same long parallel-sided interorbital region, but more lightly built throughout. Palatal foramina shorter. Hinder edge of palate with the bridges over the lateral grooves complete. Teeth conspicuously lighter and weaker than in E. bedfordice, the incisors and all the molars much narrower. Pattern in a |
