brane, which extends upon the tail, and takes it in altoge- 

 ther. The vespertiliones have also two mammae, situated 

 on the breast, pretty near the arm-pits. The tongue is soft ; 

 only in one species it is possible to perceive some papillae 

 at the basis. All the fingers included in the membrane of 

 the wings have neither nail nor unguical phalanx. 



These characters would be sufficient for the purpose qf 

 recognising the vespertiliones. But to those are also joined 

 the consideration of the teeth. These are arranged as in 

 the lemurs. The same number and same disposition of the 

 incisors prevail in both : four in the upper jaw, separated 

 in pairs, six in the lower very closely approximated to each 

 other. These teeth are not worn, they preserve their tops, 

 so that the upper are always cylindrical and pointed at the 

 extremity, and the lower divided into two lobes and cut as 

 it were in scissures. The intermaxillary bone is formed of 

 two portions not joined in front. As the upper incisors 

 form but a very narrow lodgment in this bone, they are 

 always remarkably small, and are easily disengaged from 

 their beds. 



The canine teeth, to the number of two in each jaw, are 

 the same as in all the bats. 



The cheek-teeth, on the contrary, have a form exclusively 

 proper to the vespertiliones. There are from four to six 

 on each side, according to the species. The anterior are 

 conic. The others with large coronets are bristling with 

 points. The lower ones are furrowed on the sides. The 

 upper, twice as large, exhibit moreover a coronet with an 

 oblique edge, insomuch, that they partly displace the lower 

 when the jaws are closed. These large teeth moreover are 

 hollow at their centre. In both rows they are respectively 

 engrained, and present on inspection a general appearance 

 from which it may easily be judged that they appertain to 

 insectivorous animals. 



Such are the characters which agree without exception
