uniform brown (between ‘ seal-brown” and “ Prout’s brown”),

contrasted light area, being scarcely lighter than the back, and 
passing gradually without line of demarcation into the drab-washed 
belly. Chin and throat slightly more greyish. Hands and feet

nearly as long as the head and body, well-haired throughout, 
slightly pencilled at tip, blackish brown above, dull whitish below. 
Skull conspicuously larger than that of S. minutus, but of the same 
light and delicate build. Upper unicuspids subequal in transverse 
section, the last one not smaller than the rest or outof series. All 
the teeth liberally tipped with brown. 
Dimensions of the type, measured in the flesh :— 
Head and body 50 mm.; tail 49; hind foot 11:5; ear 7. 
Skull—greatest length 17°5; basal length 15; breadth of 
brain-case 8°5; length of upper tooth-series 7-6.

Collected 28 September, 1904. 
This small Shrew belongs to the genus Sorex, which had not 
hitherto been recorded from Japan. It appears to be a member 
of the S. minutus group, but may be readily distinguished by its 
size and unusually long tail. A second specimen of it is in the 
Museum collection, obtained by Mr. Alan Owston near Tokyo.

paler. Upper surface of hands and feet pale drab. Tail short, 
much shorter than head and body, well-haired and pencilled, pale 
broccoli-brown above, rather lighter below.

than that of S. minutus, as indicated by the short tooth-row. 
Anterior incisor large, not very deeply notched. Five upper uni- 
cuspids broad, closely packed, in even slightly decreasing sequence 
to the penultimate, the fifth again slightly larger than the fourth, 
in the tooth-row, clearly visible from without. Brown on teeth 
about as in S. minutus.

Head and body (measured in skin) 55 mm.; tail (measured in 
flesh) 30; hind foot 9.

to describe a tiny Shrew obtained in Japan by Mr. Hawker. It
