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 v/hich 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. 



Sc. 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 Tamia of Illiger. For 



instance the 



Sc. striatuSf 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 j the ears 

 smooth, and skin brown, with five black stripes and two white 

 ones. 

 We ought also, most probably, to distinguish the GuerlinguetSf 

 a species with a long, and almost round tail, and an enormous pen- 

 dant scrotum. They are found in both continents.(l) 

 The following have been separated already. 



Pteromys, 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 j 

 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 have found however in the Tamise and Guerlinguets the same kind of 

 teeth as in the Squirrels and Pteromys. 



(2) Pteromys, Winged Rat.
