RODENTIA. 137 
inside of the limbs pale yellow ; a maronne coloured band behind 
the cheek. It inhabits the palms, and is extravagantly fond of 
the milk of the cocoa-nut. 
There are, also, several Squirrels in warm climates, that are 
remarkable for the longitudinal bands which vary their fur. 
Such are the 
Sc. getulus, L.; Buff. X, xxvi. (The Barbaresque.) The 
bands of which extend to the tail, and even on it. 
Se. palmarum, L.; Buff. X, xxvi. (The Palmist.) On which 
the stripes are confined to the back. 
It is probable that we shall have to separate from the Squirrels 
certain species which have cheek-pouches like the Hamsters, and 
pass their lives in subterraneous holes, the Yama of Mliger. For 
instance the 
Sc. striatus, L.; Buff. X, xxviii. .(The Ground Squirrel.) 
Which is found throughout all the north of Asia and America, 
particularly in the pine forests. The tail is more scantily sup- 
plied with hairs than that of the European Squirrel; the ears 
smooth, and skin brown, with five black stripes and two white 
ones. 
We ought also, most probably, to distinguish the Guerlinguets, 
a species with a long, and almost round tail, and an enormous pen- 
dant scrotum. They are found in both continents.(1) 
The following have been separated already. 
Preromys, Cuv.(2) 
Or the Flying Squirrels, to which the skin of the flank, extending 
between the fore and hind legs, imparts the faculty of supporting 
themselves for a moment in the air, and of making very great leaps. 
There are long bony appendages to their feet, which support a part 
of this lateral membrane. 
There is a species in Poland, Russia, and Siberia. 
Sc. volans, L.; Schreb. CCXXIII. (The Flying Squirrel.) 
Ash-coloured grey above; white underneath; size of a Rat; 
the tail only half the length of the body. It lives solitarily in 
the forests. 
One from North America. 
Sc. voluccella, L.; Buff. X, xxi. (The American Flying 
Squirrel.) Reddish-grey above ; white beneath ; size less than 
(1) We haye found however in the Tamiz and Guerlinguets the same kind of 
teeth as in the Squirrels and Pteromys. 
(2) Pteromys, Winged Rat.
