102 SEVERN FLYING SQUIRREL, &C. 
Severn river flying squirrel. 
This species is found about the Severn river in 
the southern parts of Hudson’s Bay. In the Phi- 
losophical Transactions, it is called the greater 
flying squirrel. Its back and sides are of a deep 
ash colour at bottom, ferruginous on the surface. 
The underside of the body is of a yellowish white. 
Its hair is everywhere long and full. The instru- 
ment of flying is disposed from leg to leg ; but 
does not border the fore legs. It is about the 
size of a common squirrel. 
Hooded flying squirrel. 
The hooded squirrel, according to Seba, who 
is the only author that has described it, inhabits 
Virginia. Its lateral membrane begins at the 
chin and ears, and extends from the fore to the 
hind leg. It is reddish above, cinereous tinged 
with yellow beneath. Its ears are large and oval, 
American flying squirrel. 
This animal, which is a native of most parts of 
North America, has large black eyes, circular 
paked ears, and a hairy membrane extending nearly 
round the bodj. The tail, which tapers to a 
point, has its hairs disposed flat-ways on its sides. 
The upper parts of the body are of a cinereous 
brown ; the belly is white, tinged with yellow. 
The membrane passes the fore and hind legs, to the 
tail ; on the fore legs it adheres as far as the toes, 
and includes a peculiar bone, which is attached 
to the wrist, and helps to stretch out this skin in 
flying ; and on the hind leg it extends to the an * 
eies.
