350 ME. OLDFIELD THOMAS OX [Nov. 28, 



Type. Female. B.M. No. 6.1.4.219. Origiiml no. 117. Col- 

 lected 15 November, 1904. 



Of the large series of M. s2}eciosus from Hondo, enumerated 

 just previously, only one has a hind foot as much as 25*5 mm. in 

 length, the majority of the adults ranging from 23 to 25. And 

 of those from Shikoku and Kiushiu one only has 25'5, and 

 one 26. On the other hand, the four from Hokkaido are all 

 measured as 26 or over, and in addition their skulls are rather 

 more elongate, especially in the muzzle, than those of the more 

 southern form. 



Under these circumstances, in view of the general difference 

 between the faunas of Hondo and Hokkaido, I have thought it 

 advisable to give the form from the latter island a special sub- 

 specific name, like as it is to its ally in all other respects.

Two specimens of this pretty little species were obtained by 

 Mr. H. Pryer in the Yokohama region in 1888, but it was only 

 when Mr. Gordon Smith's collection was being worked out that 

 it was recognised as new. It would appear to be generally dis- 

 ti-ibuted over Hondo, Shikoku, and Kiushiu, and is represented 

 in Hokkaido by a short-eared subspecies. 



Its mammary formula, as previously stated with doubt, is 

 2—2 = 8.

 from the Izu peninsula : — •
