This Shrew is distinguishable from all other Eastern species 

 known to me by its heavily pigmented teeth. In general appear- 

 ance it is very like S. annexus Thos., but besides the difFei-ence in 

 the teeth, its more haiiy tail and differently coloui-ed teeth at 

 once distinguish it. 



I owe to the kindness of Dr. Allen examples representing his 

 >S'. buxtoni, described from Gichika Ochotsk Sea, and find that it 

 has a smaller and slenderer skull (greatest breadth in type 8 mm.) 

 and that its teeth are not more heavily pigmented than usual.

Quite like the true S. shinto Thos., of Hondo, in all respects, 

 but larger throughout, except that the tail is only of about the 

 same length.

This Shrew is evidently of the same type as the Hondo S. shinto, 

 discovered previously by Mr. Andeison, but differs, as most 

 northern forms so often do, by having a larger body, with a 

 proportionally shorter tail. I can find no dift'ei'ence whatever 

 between the Saghalien and Hokkaido specimens.
