In many respects the Pigmy Shrews resemble the small 

 species of Sorex, the common Shrews, except in the matter of 

 size. Pigmy Shrews seem to be rare and have never been 

 found in even moderate abundance. As an example of the 

 difficulty in securing specimens of this genus, it may be pointed 

 out that only as recently as 19 10 a new Pigmy Shrew, Micro- 

 sorex hoyi winnemana, was described from Virginia. In 

 spite of the many years of work and study upon the mammals 

 of the Atlantic seaboard, this tiniest of mammals had escaped 

 discovery. 



It is to be expected that the life-history of this genus is very 

 much the same as for Sorex, although very httle has been
