Type. Female. B.M. No. 6.1.4.219. Original no. 117. Col- 
lected 15 November, 1904. 
Of the large series of JZ. speciosus from Hondo, enumerated 
just previously, only one has a hind foot as much as 25:5 mim. 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- 
tributed 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. 
The following are the flesh measurements (in mm.) of a pair 
from the Izu peninsula :-—
