The genus Microsorex (Baird, 1877) may be known by 

 its small size and peculiar teeth which resemble those of Sorex 

 in number but differ in their proportionate sizes, etc. (see Fig. 

 251 — 3). Its third upper unicuspid is very minute and nearly 

 hidden between the second and fourth. It has on the inner 

 side of the first and second unicuspids a distinct secondary 

 cusp. Its mandible is short and heavy; the feet are not 

 fringed with bristles, that is, they resemble those of the Com- 

 mon Shrew. 



At first glance the Hoy Shrew (see Plate C) looks like 

 a very small Masked Shrew, but the generic characters dis- 

 tinguish it.
