Remarks. — Specimens from Garrett County and Allegany County 

 appear somewhat darker in summer and winter pelage than specimens 

 from farther east in the State and may represent intergrades with the 

 southern Appalachian subspecies T. h. ahieticola. 



SOUTHERN FLYING SQUIRREL 

 Glaucomys volans volans (Linnaeus) 



[Mus] volans Linnaeus, Syst. Nat., ed. 10, 1 : 63, 1758. 



Type locality. — Virginia (fixed by Elliot, Field Columb. Mus., Zool. Ser., 2: 

 109, 1901). 



General distribution. — From central Minnesota, Upper and Lower Peninsulas 

 of Michigan, southeastern Ontario, New York, and southern New Hampshire, 

 south to North Carolina and Tennessee, west to eastern Kansas and Nebraska. 



Distribution in Maryland. — Probably abundant in all sections of 

 the State where there is suitable habitat. No specimens or records are 

 available, however, from the Eastern Shore, Ridge and Valley, and 

 Allegheny Mountain sections, but this probably indicates that these 

 sections have not been systematically trapped for the species rather 

 than a scarcity of the animals themselves. Flying squirrels are noc- 

 turnal, shy, and seldom observed. 



Distinguishing characteristics. — Teeth 1/1, 0/0, 2/1, 3/3, = 22; a small 

 squirrel that is characterized by a ''flying membrane", a loose fold of 

 fuUy furred skin connecting the fore and hind limbs from wrists to 

 ankles. The tail is broad, flattened, and almost paraUel-sided, with 

 the tip rounded; pelage extremely soft and dense; coloration of upper 

 parts varies with season and age, but is generally grayish brown; 

 under parts ususally white or creamy white in coloration, with the 

 white extending from the base of the hairs to the tip; dark brown 

 streak extending along side edge of "flying membrane"; tail grayish 

 above, cinnamon below; forefeet white, hind feet brown except for 

 some white on toes. 



This species may be distinguished from all other squirrels in Mary- 

 land by the distinctive "flying membrane." The northern flying squir- 

 rel, Glaucomys sahrimis, has not as yet been reported from Maryland,
