SEROT1NE BAT. 109 



The face is nearly bare ; the upper lip very tumid, 

 furnished with tubercles whence issue some hairs ; 

 the muzzle short, broad, thick, and tumid ; the nose 

 a line and a half in breadth anteriorly ; the nostrils 

 rounded ; the forehead very hairy ; the eyes small ; 

 the ears ovate, triangular, having their inner margin 

 much arched, their extremity blunt and bent out- 

 wards, the external surface hairy for half its extent, 

 the rest bare; the tragus elongated and semicordate; 

 four grinders on each side in the upper jaw, and five 

 in the lower ; the head extending four lines beyond 

 the carpus, when the wings are folded. In the male 

 the fur is deep chestnut, passing beneath into 

 yellowish-grey, which contrasts strongly with the 

 blackish-brown colour of the wings and interfemoral 

 membrane. The hair on the back is long, glossy, 

 and silky. The females differ from the old males 

 more than in any other species, the colours of the 

 fur being much paler. Young individuals have the 

 colours darker. The length of the head and body 

 is two inches nine lines, of the tail two inches ; and 

 the extended wings measure from twelve to fourteen 

 incnes.
