THE MAMMALS OF NEW JERSEY. 8s 
The true Hudson Bay red squirrel (Sciwrus hudsonicus ), is re- 
stricted to the far north, from Labrador and Hudson Bay to 
Alaska. From Maine and Canada south through the Alleghanies 
occurs variety S. h. gymnicus, the southern red squirrel, and on 
the Atlantic slope to Virginia the southern form S. h. loquax. All 
the New Jersey examples seem to belong to the last though some 
of those of the extreme northwest may tend toward the duller 
erayer, gymnicus, which, in the winter, has the lower surface 
tinged with gray.

PLATE 38. 
Length 9.40 inches. Fur soft and dense like that of a mole. 
Drab above irregularly tinged with russet, slightly brighter in 
summer, under parts pure white. 
During the daytime some hollow tree or some crevice or cranny 
under the eaves of an old house shelters the flying squirrels, and 
only at dusk do we see them come forth; running up the trunk of 
a tree and launching forth with legs extended, they sail gracefully 
downward to alight on another trunk and again begin the ascent. 
Large numbers usually occupy the same hollow tree, and by 
rapping upon it they may often be driven out even though it be 
daytime. 
Flying squirrels seem to be pretty well distributed over the 
State, though I am not sure of their occurrence in the heart of
