 200-300'. 



General characters as in true geisha, but just as the ears average 

 shorter in specimens from Hokkaido*, so here they are unifoi-mly 

 rather longer than in Hondo examples. Of the 25 specimens 

 from Izuhara, in the S. Island of Tsu-shima, no less than 16 are 

 labelled as having ears 15 mm. in length, three have them 14, 

 two 14'5, two 15*5, and two 16. In true geisha the ears are 

 about 14 mm., and in hokkaidi 13 mm. 



The Sasuna specimens are not quite so uniform as those from 

 Izuhara. 



Dimensions of four specimens from Izuhara : — 

 c^* . Head and body 81 mm. ; tail 91 ; hind foot 19*5 ; ear 15.

Skull of type — greatest length 24 mm. ; basilar length 1 8 ; 

 length of upper tooth-series 3'5. 



Hah. Tsu-shima — type from Izuhara, South Island. 



Type. Adult male. B.M. No. 8.2.26.50. Original number 

 1228. Collected 10th January, 1907. 



" The most common of the Tsu-shima mammals. Found in 

 the forested hills and canyons." — M. F.A. 



Pui'ely a Japanese type, no Mouse at all allied occurring in 

 Korea. 



11. Apodemus minutus Pall. 

 S. 1235. Izuhara, S. Island. 



Head and body 54 mm. ; tail 53 ; hind foot 14'5 ; ear 9. 



The «ingle specimen appears to be more or less intermediate 

 between the continental subspecies ussuricus and the Japanese 

 japonicus, but no very definite opinion can be expressed about it 

 without further material. 



[12. Cervus sika Temm, 



" Said to have been very abundant before the introduction of 

 good firearms ; now rare and not seen by me or my assistant." —
