TAPirOZOUS DOBSONI, 121 



NOTE xxxn. 



ON A NEW BAT, TAPHOZOÜS DOBSONI 

 FROM MADAGASCAR. 



BY 



Dr. F. A. JENTINK. 



Febr. 1879. 



Taphozoxis D obsoni. 



After the careful examination by Dobson ^) of the walk- 

 ing and suctorial organs of certain Bats , it is evident , 

 that although there is a great difference in external form , 

 the structure and the physiological signification are the 

 same. The very highly developed suctorial disks of Thy- 

 roptera tricolor and the comparatively simple adhesive sole 

 of the foot and thumb of Vesperugo pachypus present a 

 difference of degree only and not of function. 



Spix ^) is the first who has discovered and described 

 a Bat , Thyroptera tricolor from Brazil , with sucking-cups. 

 Several years after , Gray ^) announced the very curious Mys- 

 tacina tuherculata of New-ZTealand , with a remarkable 

 climbing aparatus. 



Meanwhile Temmink *) cursorily mentioned "les pieds a 

 plante large et déprimée" of his Vespertilio pachypus.
