ORDER CARNASSIER. 155 



gave to two species of the Indian bats, the names of flying 

 dog and flying-dormouse. Daubenton adopted this sort of 

 nomenclature for the purpose of giving an idea of the relative 

 sizes of these animals, not because there was any resem- 

 blance between them and the species whose names they 

 received in part. 



The ears of this vespertilio are oval triangular, one-third 

 the length of the head. The auricula is long, and termi- 

 nates in a point ; it is of a fawn-coloured brown. The 

 muzzle is broad and thick, the lips long, but neither in- 

 flated nor varicose. The end of the tail is disengaged be- 

 yond the interfemoral membrane. Daubenton gives it but 

 two upper incisors ; there are two others, but very small. 

 It is a native of Virginia, and was made known by Adan- 

 son's voyage to Senegal. 



The vespertilio maximus is the largest of this tribe. Its 

 ears are oval, shorter than the head ; the auricula subu- 

 lated, and the muzzle long and pointed. The fur is brown ; 

 marron above, clear yellow on the sides, and dirty white 

 under the belly. It inhabits Guiana. 



The vespertilio Noveboracensis, New-York bat, has been 

 described by Pennant ; it seems to belong to this genus, 

 though this clever naturalist says that it has no upper in- 

 cisors ; Pennant, probably, saw an imperfect individual. 

 The ears are short, large, and rounded. It is remarkable 

 for a white spot at the origin of the wings. It is about the 

 size of the noctule. 



The (vesp. lasiapterus ,) lasiopter bat of Shaw, in size, 

 form of head, and colour, strongly resembles the serotine; 

 but it differs in having the membrane of the wings covered 

 with hair internally for about one half its length. 



The (vesp. villosissimus,) hairy bat, is a species of Paraguay, 

 found in d'Azzara, and called villosissimus by M. Geoffroy, 

 because the hair is longer than in all the other bats of that 

 country, and extends even over the interfemoral membrane.
