Sorex hoyi Baird. 
Hoy’s shrew is tolerably common at North Bay. I secured only 
one at Peninsula Harbor. 
Neither Brooks nor Gapper mentions this shrew. 
Hoy’s shrew avoids bogs and heavy woods. At North Bay I 
invariably found it in dry clearings and gardens. Several fell into 
pitfalls dug in a garden, and others entered traps set beneath stumps 
in a meadow. The one taken at Peninsula Harbor was found by a 
dog under the rotting trunk of a small tree in an open upland 
4 prairie.’ 
A female taken at North Bay on August 22 has only four mammae, 
all inguinal. In this character it differs from Sorex personatus and 
agrees with Blarina bremcauda. A reduction in the number of 
mammae is probably characteristic of the subgenus Microsorex.

Blarixa rrevicauda (Say). 
The short-tailed shrew is abundant at North Bay, Peninsula Har¬ 
bor, and Nepigon. 
Common at Mount Forest (Brooks). 
Gapper described this shrew as a new species under the name 
Sorex talpoides from the region between York and Lake Simcoe. 
At North Bay I caught one alive in a dry pitfall. The animal 
showed no sign of fear, but sprang savagely at my hand whenever 
I reached toward him. He gave every indication of good vision 
by dodging or attacking small objects tossed at him. He also 
evinced great acuteness of hearing, as the slightest noise caused him 
to start and assume a defensive attitude. During the ten minutes 
that I teased him before setting him free lie kept up a continuous
