lip and the end of the muzzle above. On the back the fur is very 

 short, and strictly limited to it, not extending upon the wing- or 

 interfemoral membrane, and leaving a considerable portion of the 

 posterior part of the back naked. The skin of this part and of the 

 wings near the body is covered with transverse and longitudinal 

 ■wrinkles, as in Taphozoiis nudiventris and in CJieiromeles torquatus. 

 The distribution of the fur beneath is somewhat similar ; but a few 

 fine hairs appear upon the wing-membrane near the body and upon 

 the wings and forearm ; the remainder of the wings is quite naked. 

 The extremity of the tail has a few long hairs, as in Taphozous, and 

 also the backs of the terminal phalanges of the feet. 



The nasal bones are much expanded laterally, forming roimd 

 prominent projections above the infraorbital foramen on each side ; 

 immediately behind the frontal is slightly concave ; there are no 

 postorbital processes ; zygomatic arches extremely slender ; bony 

 palate very short, scarcely extending in the middle line as far back 

 as the last molar ; roof of the mesopterygoid fossa continuous with 

 the basisphenoid and the basioccipital. 



PremaxiUary bones very slender, forming a commissure in the 

 middle line, each bone supporting on its outer side an extremely 

 slender incisor, which is directed outwards and downwards towards 

 the canine of the same side. The single upper premolar exceeds 

 the molars in vertical extent, with a second vertical basal cusp on 

 its outer and anterior side ; last upper molar less than half the ante- 

 penultimate molar. 



The Asiatic representatives of this species differ from the African 

 in their shorter fur, which does not anywhere extend upon the 

 m.embranes, and in their much shorter tail and longer thumb. In 

 all other respects they agree so closely together that I am unable to 

 consider them distinct species. In the following Table the mea- 

 suremersts of two perfectly adult specimens, one from Africa (the 

 type of the species, preserved in the Paris Museum), the other from 

 itaehh, in India, are compared: —
