72 Jackson Notes on the Mammals of Southwestern Missouri. 

 Sciuropterus volans subsp. 



FLYING SQUIRREL. 



Having seen only one flying squirrel in the district, and not having cap 

 tured that one, I am unable to refer it Bubepeeifically. However, the rusty 

 suffusion' on the ventral surface of the tail and the dusky feet may indicate 

 the subspecies (jitcrcrfi. The squirrel, which was closely observed, was 

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

 at Lakeside in Jasper County. 



Tamias striatus venustus Bangs. 

 CHIPMUNK. 



A single chipmunk taken among the wooded hills eight miles south of 

 Carthage proves to be 71rr///m.s'.s. reuiixttm. This specimen, a female, taken 

 November 4, 1005, measures as follows : Total length, 218mm.; tail ver 

 tebrae, 78.5 mm. ; hind foot, 33.2 mm. 



At Lakeside, Jasper County, October 15, 1904, three chipmunks were 

 seen gathering acorns and hickory nuts along the rocky, wooded bank of 

 Center Creek in Lakeside' Park. Again on May 11, 1905, near the same 

 locality, a Tamia* was seen running from one hole to another on a steep, 

 rocky bank not more than four feet above water. 



Chipmunks are said to occur around Webb City. 



Mus musculus Linnaeus. 



HOUSEIMOU8E. 



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

 only'in the towns but along every country road and hedge. I have caught 

 them in weed patches upon the open prairie a mile from any building. 



Mus norvegicus Erxleben. 



NORWAY RAT. 



The common brownPrat of the barns and granaries, unlike the house 

 mouse, is confined chiefly 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). 



PRAIRIE WHITE-FOOTED MOl'SK. 



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

 by Microtus ochrogaster. It favors patches of open brush-land but on one 

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

 on a hill. Specimens taken are very nearly typical michiganensis with 

 scarcely an approach towards pallascens. Average measurements of three 

 males: Total length, 139.7 mm.; tail vertebrae, 52 mm. ; hind foot, 17 

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

 mm. ; hind foot, 19 mm. 



Other forms of the genus Peromyscus probably occur but none were 

 taken.
