PITYMYS PINETORUM SCALOPSOIDES (Audubon and Bachman) 



NoKTHERN Pine Mouse 



The pine mouse is a burrower, spending most of its life in under- 

 ground runways. As the name implies, it seems to show some prefer- 

 ence for woodlands, especially pine woods. It is frequently found, 

 however, along the borders of cultivated fields, meadows, and pas- 

 tures adjoining woods, and occasionally in wet bottomland timber. 

 Along Peters Creek, near Gilboa, pine mice were trapped in nmways 

 under dry matted leaves near an old rail fence in a growth of hemlocks. 



F. E. Brooks (1911, p. 18) records this mouse from Morgantown, 

 MonongaHa County; Terra Alta, Preston County; French Creek and 

 Buckhannon in Upshur County; and Peterstown, Monroe County.

ONDATRA ZIBETHICA ZIBETHICA (Linnaeus) 



Common Muskrat 



According to A. B. Brooks (1929, p. 544) the muskrat inhabits 

 streams and marshes throughout the State. The National Museum 

 party did not collect any specimens. Tracks were seen along the 

 Ohio River above Point Pleasant, Mason County. Those hving 

 along Muddlety Creek on the Tinnel farm were driven away appar- 

 ently by spring floods in 1936. Similar conditions seemed to prevail 

 along Sugar Creek south of Philippi in Barbour County. Hollister 

 (1911, p. 18) records four specimens from "White Sulphur Springs, 

 Greenbrier County.
