According to the indicia of M. Geoffroy, we al~o separa~e from the Pteropi the CEPHALOTES which have the same kmd of g:mders, but whose index, short, and consisting of three phalan~es, l.Ike t~at of the preceding, has no nail. The membranes of their wmg~, lD· t d of meeting at the flank, are joined to each other on the middle s ea 1 . d' 1 of the back, to which they adhere by a .ve.rt ical and ongitu ma par· tition. Very often they have but two mcisors. c. Peronii, Geoff.; Ann. du Mus., XV, pl. 4. Brown or red. From Timor. The Pteropi being taken away, we have the true BATS 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 nuU:ber of false molars.

Nat. article Rouss:ETTE,-gives US 1 monography of this genus, in which he forms the Pter. personatus of Temm., and some neighbouring species into the subgenus P .A.CHISOMA, which has four ~~Iars less than the others, and the zygomatic arches more projecting; the Pter. mzmtnlll or rostratus into the subgenus ~IA.cnoGLOSs.A., in which the muzzle is longer an.d more slender, and where there are spaces between the grinders. Its tongue 11 thought to be extensible. He, finally, separates the Gephalote of Peron from that of Pallas, and gives to the first the name of HYPODERMis, on account of the com· plete dorsal insertion of the membrane of its wings. CARNARI.A. 79 subgenus excepted, the membrane is always extended between the two legs. They should be divided into two principal tribes. The first has three ossified phalanges in the middle finger of the wing, but the remainder, including the index itself, consists of but two. To this tribe, which is. almost exclusively foreign, belong the following subgenera. MoLossus, Geoff.-DYSOPEs, Illig. The muzzle simple; ears broad and short, arising near the angle of the lips, and uniting with each other on the muzzle; the tragus short, and not enveloped by the conch. The tail occupies the whole length of their inter-femoral membrane, and, most generally, even extends beyond it. They have very seldom more than two incisors in each jaw, though, according to Temminck, several of them have at first six below, of which four are successively lost. The DINOPS of M. Savi belong to this Molossus, with six inferior incisors. There is one species in Italy-Dinops cestonii, Savi, Giorn. de Letter., No. 21, p. 230. M. Geoffroy calls those in which he has counted four inferior incisors N YOTINOMUS. ( 1) The Molossi, at first, were only found in America ;(2) at present, however, we know several of both continents.(3) Some of them have the hinder thumb placed at a greater distance from the first finger than the fingers are[.from each other, and endowed with a separate motion, a character on which, in a species where it is very strongly marked, M. Horsfield has established his genus CHEIROMELEs.( 4) It is here, perhaps, that we should also place the THIROPTERA of Spix, which appear to have several characters of the Molossi, and {1) The Nyctinome d'Egypte, Geoff., Eg.
