78 MAMMALIA. 
Pter. vulgaris, Geoff.; Buff. X, 14. (The Common Rous- 
sette.) Brown, face and sides of the back fawn-coloured. From 
the Isle of France and Bourbon, where it is found on the trees 
in the forests. Its flesh has been compared to that of the hare 
and partridge. mF 
Pter. rubicollis, Geoff.; Buff. X, 17. (The Red-collared Rous- 
sette.) Greyish brown, the neck red. From the same islands, 
where it lives in the hollows of trees and in caverns.(1) 
b. With a small tail and four incisors in each jaw, — 
M. Geoffroy was the first who described the species of this 
subdivision. One of them grey and woolly, Pter. eg¢ypticus, is 
found in the caves of Egypt. A second is reddish, and has a 
somewhat longer tail, half involved by the membrane—Peéer. 
amplexicaudus, Ann. du Mus. tom. XV, pl. 4. From/the Indian 
Archipélago, &c.(2) 
ce. According to the indicia of M. Geoffroy, we also separate from 
the Pteropi the Crpnatores which have the same kind of grinders, | 
but whose index, short, and consisting of three phalanges, like t 
of the preceding, has no nail. The membranes of their wings, in- 
stead of meeting at the flank, are joined to each other on the middle 
of the back, to which they adhere by a vertical and longatygdinal par- 
tition. Very often they have but two incisors. 
C. Peronii, Geoff; Ann. du Mus., oT pl. 4. Biten or red. 
From Timor. . te 
The Pteropi being taken away, we have the true Bars left, which 
are all insectivorous, and have three grinders on each side in each ~ 
jaw, bristled with conical points, that are preceded by a variable 
number of false molars. Their index never has a nail, anne

M. Isidore Geoffroy—Dict. Class. d’Hist. Nat. article Rovsserm, gives ts a a 
monography of this genus, in which he forms the Pter. personatus of Temm., and — 
some neighbouring species into the subgenus Pacuisoma, which has four molars 
less than the others, and the zygomatic arches more projecting; the Pter. minimus 
or rostratus into the subgenus Macroexossa, in which the muzzle is longer and 
more slender, and where there are spaces between the grinders. Its tongue is 
thought to be extensible. He, finally, separates the Céphalote of Peron from that 
of Pallas, and gives to the first the name of HypopEermis, on account of the tg 
plete dorsal i insertion of the membrane of its wings. ; a r 4 A
