THE SAVAGE WORLD 
The Flying Squirrel, or Red Yaguan (, Sciuropterus volucella ), is about a 
foot in length, half of this belonging to the body, and is provided with a 
membrane on each side, which extends as far as the wrist and ankle. It is 
not truly a flyer, for the membrane acts rather as a parachute, and when the 
squirrel wishes to rise it is compelled to leap upward so as to fall downward 
at the right angle. There is also a 
European species ( Sciuropterus volans ). 
The largest species is the Taguan 
(.Pteromys petaurista ). 
The Scale-tailed Squirrel ( Anorn - 
alums fraseri ) is a flying squirrel, but 
the scales on its tail serve the uses of 
a fifth foot. It is African in its habi¬ 
tat, as is also another species, the 
Shining Scale-tailed Squirrel ( Anorn- 
alums fulgens). 
The Red Squirrel [Xeres hudsonius) 
is the American representative of the 
common squirrel of Europe. It is fre¬ 
quent in the Northern States, and is 
sometimes called the hackee , or chick¬ 
aree. 
The Bobac ( Aretomys bobac ) is 
Colorado marmot ( Spermophilus citillus).

yellowish-gray, with dark mottlings, the under parts, throat and tail being 
russet, and the muzzle silver-gray. Its habitat is northern Europe and Asia, 
but it seeks lower altitudes than the aipme species. 
The Woodchuck, or Ground Hog ( Aretomys empetra) , has a great variety 
of names, not only its 
numerous popular nick¬ 
names, but also more 
thau its share of scien¬ 
tific titles. One reason 
of his various names is 
no doubt found in the 
fact that he is very 
widely distributed, for he 
is found in the Canadas, 
as far south as the Caro- 
linas, and as far west as 
the Rocky Mountains 
The body is thick and 
squatty, and the legs 
peculiarly short. The 
body is about eighteen 
inches long, the tail about four. The color varies in different individuals. 
The woodchuck does not go far from its burrow during daylight, but after 
sundown comes out to forage, hunting for grass, fruits and vegetables, often 
doing great damage to clover fields and kitchen gardens. They are solitary in 
their habits, not forming communities of more than a single family. They
