Hoy Shrew iill 



personatus, so that we must rely on size and dentition for 

 identification. 



Three races are recognized: 



hoyi Baird, the typical form. 

 extmius Osgood, larger and paler. 

 alnorum Preble, like hoyi, but larger, and lower parts 

 not tinged with buffy. 



This, the least of our beasts, was first discovered at Racine, 

 Wis., but has since been found in various localities, from 

 Nova Scotia to British Columbia, as shown on the map, No. 59. 



Dr. C. Hart Merriam records' a specimen from Red 

 River Settlement. On this rests its claim to being Manitoban. 



Little is known of its habits, but probably they differ 

 little from those of Sorex personatus. 



The following brief account is the longest I can find:^ 

 "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 prairie. 



"A female taken at North Bay on August 22 has only 4 

 mammae; all inguinal. In this character it differs from Sorex 

 personatus and agrees with Blartna brevicauda. A reduction 

 in the number of mammae is probably characteristic of the sub- 

 genus Microsorex." (Miller.)
