I. ON A NEW SUBSPECIES OF FLYING SQUIRREL 

 FROM NEBRASKA^ 



BY MYRON HARMON SWENK 



Flying squirrels in Nebraska are confined to the timbered 

 bottoms along the Missouri river in the southeastern part of the 

 state, where they are not common. Most of the records of their 

 occurrence are from the vicinity of Nebraska City, Otoe county, 

 though there are several records of the animal having been seen 

 or captured in the vicinity of Peru, Nemaha county. We have 

 long known of the large size of the Nebraska flying squirrels, and 

 the recent securing of a good specimen in the flesh from Nebraska 

 City enables the describing of
