Sorex pcrsonatus. Masked Shrew. — In this county the 

 masked shrew is usually found in sphagnum and tamarack 

 bogs. There are records for a tamarack bog, three miles south 

 of Ann Arbor, and for Honey Creek, three miles west of Ann 

 Arbor. I have found it mostly under old logs and in stumps 

 in rather moist situations. 



Blarina brcvicanda talpoidcs. Short-tailed Shrew. — Com- 

 mon in swamps, woodlands, and even in meadows, where it 

 has its own runways and also uses those of the meadow mouse, 

 on which it largely feeds. 



This shrew is diurnal as well as nocturnal, and I have often 

 seen it in its runways. It is active all winter, and its tunnels 

 may often be seen in the snow. While trapping in Steere's 

 bwamp, south of Ann Arbor, a Synaptomys coopcri in a trap 

 was eaten by one of these shrews, which was later caught in 

 the same trap. 



Cryptotis parra. Small Shrew. — The first record for the 

 county was obtained in 1902 at Ann Arbor. In February, 

 1904, one was found in a barn three miles east of Ann Arbor. 

 At Portage Lake, in 19 16, a house cat brought two individuals 

 to her kittens on October 29 and 31, respectively. The speci- 

 mens taken by me were found in grassy places, usually where 

 briers and shrubs were intermingled with the grass, but not in 

 the woods. 



Myotis liicifiigns hicifugus. Little Brown Bat. — Almost 

 every winter individuals have been found in the building of 

 the Museum of Zoology, at Ann Arbor, where they have been 

 awakened by the heat long before insects were flying about. 

 Max Peet took one at Ypsilanti June 6, 1904. 



Myotis subiilatits siibuJatits. Say Bat. — In 1902 one was 

 found alive in one of the buildings of the University of Mich-
