356 MR. OLDFIELD THOMAS ON [ Nov. 28, 
would seem to be widely spread over Southern Hondo, 8. of 35° N., 
and to be common in both Shikoku and Kiushiu, its distribution 
thus corresponding with that of somany Japaneseanimals. There 
does not appear to be any tangible difference between the speci- 
mens from the Izu Peninsula, from the type locality, Kobe, or from 
the two southern islands, Shikoku and Kiushiu. In each place, 
however, there seems a good deal of variability, both in colour, 
which ranges from a light russet-brown to a dark “ vandyke- 
brown,” and in tooth-pattern. 
In the latter respect the following description applies to the 
majority of the specimens, the type being among the minority , 
but there is every gradation between the two. 
M? with the first outer and inner re-entrant angles subequal, 
the latter being much deeper in the type; second and third 
spaces partially, and in some cases fully, separated, not continuous 
as in the type; fourth space not always separated off from the 
posterior C; head and tail of the C strongly developed, with a 
deep re-entrant angle between them, as deep as the one before the 
head, the third internal projecting angle of the tooth; there are, 
therefore, three subequal internal re-entrant angles, while in the 
type there are two deep ones only (the second deeper than is 
shown in my figure and running more directly backwards), the 
third being represented by a quite inconspicuous concavity. 
Similarly on the outer side of the tooth the third concavity is 
usually far more marked than in the type. As a result of these 
variations in the depths of the re-entrant angles, the whole tooth 
appears more bilaterally symmetrical than in the figured specimen. 
Below, the spaces of m, are usually less uniformly coalesced with 
each other, and the slight antero-internal concavity of the front 
trefoil is often developed into a well-defined re-entrant angle, so 
that there are four inner re-entrant angles to the tooth instead of 
three. 
The measurements (in mm.) in the flesh of two Kiushiu adults 
are as follows :— 
gS. Head and body 100; tail 50; hind foot 17-5; ear 11. 
Pray! tas » 103; ,, 49; » 180; ,, 12. 
With regard to the number of the mamme, there appear to be 
only 6, two inguinal pairs and a posterior pectoral pair, no trace 
of an anterior pectoral pair being discoverable. But the exami- 
nation has only been made on skins, none of them killed in the 
breeding-season, and must therefore not be looked on as final.
