Sciuropterus volans su1)sp. 



FLYING SQUIRREL. 



Having seen niily oiic flying sqnirrcl in thiMlistrict, and not liaving cap- 

 tured that (inc, I am unal^lc to refer it subspedtically. However, the rusty 

 snflusion on the ventral surface of the tail and the dusky feet may indicate 

 tlie sulisjiecies qiwrccti. The S(|uirrel, wliieh was closely ol)S('rved, was 

 driven from a woodpecker's hole in an old sycanioi'e stub on the bottoms 

 at Lakeside in Jasper ("onnty. 



Tamias striatus venustus Bangs.

Mus musculus Linnaeus. 

 HOUSE MOUSE. 

 This little pest is as abundant as it is useless. House mice are found not 

 only in tlie towns ])ut along every country road and hedge. I have caught 

 them in weed patches upon the open i^rairie a mile from any building. 



Mus norvegicus Krxle1)eu. 



NORWAY RAT. 

 The common brown rat of the barns and granaries, luilike the house 

 mouse, is coniined ehietly to the vicinity of human habitations. Much 

 less generally distributed than in the northeastern States and not such a 

 nuisance; nevertheless they are rapidly increasing in numbers. 



Peromyscus michiganensis (Audubon and Bachman). 



I'UAIRIK WHITE-FOOTED MOUSE. 



This is a common mouse of the fields and is exceeded in abundance only 

 by Microtiin orhroganUn-. It favors ])atchesof open brush-land but on one 

 occasion a young male was captured under a log in heavy timber high up 

 on a hill, ^'pecimens taken are very nearly tyi>ical }iuc}ili/(iii(')isis with 

 scarcely an a]ii)roach towards 7;ff//r^s•^^/^s■. Average measurements of three 

 males: Total k'ugth, l.'!!).? mm.; tail verte])rae, 52 nmi. ; hind foot, 17 

 mm. Average of two females : Total length, 143 mm. ; tail vertebrae, 57 

 mm. ; hind foot, l'.> mm. 



Other forms of the genus I'croiiii/xciix jjrobably oci'ur but none were
