SAILING SQUIRREL. 
Indian paper. In other parts, it is also very 
thin, of a clear texture, and garnished with 
small chesnut hairs. Near the fore and hind- 
feet, it becomes thicker ; and rises in the form 
of a bag, widest at the thighs, and growing 
gradually narrower towards the pavv^s. This 
part is closely covered with brown and black 
hairs. On the fore-paws it appears loose, 
hangs down like a rag, and is covered with 
thick hair. The external edges of this skin 
are bordered with a thick selvage of black and 
grey hairs. The upper part of the head, tlie 
back, and the origin of the tail, are covered 
with pretty long thick hairs ; black in the under 
part, and mostly of a greyish white colour at 
the summits, The hairs of the tail are black ; 
more grey near the body; and so disposed, as 
to make the tail appear round. The cheeks 
are of a greyish brown colour ; and the throat, 
breast, and belly, are of a clear whitish grey. 
On the under side of the membrane, there are 
also grey hairs, but they are very thinly scat- 
tered.'* 
It is easy to perceive, in these di(Fercnt de- 
scriptions, that the Sailing Squirrels are by no 
means uniformly alike.
