tives of the Jerboa in South Africa. Their habits are about the 
same as the other members of the genus. In point of fact, they 
re'semble Hares in size, although they are more slenderly made. 
Only one species is known. 
Under the name of Pouched Pats, we shall place together a 
certain number of American Podents, which are characterised by 
the possession of large and deep cheek-pouches. These are the 
Saccomys and the Saccophorus. 
The Saccomys Genus . — The Saccomys resemble the Jerboa in 
the length of their hind-legs, and their habit of leaping. They 
are for the most part natives of the country lying around the 
Fig. 190. — Pouched Eat ( Saccophorus borealis ). 
Gulf of Mexico, and are about the size of a Water-Pat. We are 
in possession of but little information as to their modes of life.

them. Flowers, however, can only form a part of their alimentary

their strength without the assistance of other substances. 
The Saccophorus Genus . — This animal is a native of the regions 
to the north of the preceding. Their name signifies sack-bearer. 
They have immense cheek-pouches, which sometimes hang down 
to the ground, and assume a most extraordinary development. 
These sacs are used as a temporary receptacle for provisions
