14 VESPERTILIONIDJE. 



the interfemoral membrane, but does not extend upon it; laterally it 

 covers a very narrow portion of the wing membrane, above and 

 beneath, along the sides of the body. The interfemoral membrane is 

 naked above, except a few fine and invisible hairs on the first and 

 second vertebra. Beneath it is covered for more than two-thirds its 

 extent with short greyish hairs, thickest at the root of the tail. 



Above and beneath deep black or very dark brown, the extreme 

 tips on the posterior half of the back greyish ; beneath the tips of 

 all the hairs are greyish; cutaneous system black; the nose, ears, 

 and all the naked glandular prominences on the upper lip intensely 

 black; upper incisors nearly equal in length; the inner one on each 

 side bifid, its outer and shorter cusp directed slightly backwards and 

 in a plane posterior to the outer incisor, which equals or somewhat 

 exceeds it in vertical extent; lower incisors crowded, overlapping; 

 first upper premolar small, quite external to the tooth row, not visible 

 in the smalt northern forms; second premolar close to the canine. 



Length. — Head and body I'd" to nearly 2 inches, tail I'd", free from 

 membrane 0'12", ear 0-G2'', tragus 0-23", forearm 1'35', third finger 

 2-2", fifth finger 1-6". 



Hah. — Sind, the Deccan, Khasia Hills, Java, Canary Islands, 

 Switzerland, and China.

Muzzle short, obtusely conical, smoothly rounded off, naked ; 

 nostrils close together, opening by simple lunate apertures in front or 

 sublaterally, their inner margins projecting ; ears longer than broad, 

 generally much shorter than the head with rounded tips, the outer 

 margin terminating behind the angle of the mouth in a distinct convex 

 lobe. Tragus tapering, generally subacutely pointed and curved inwards. 

 Tail shorter than head and body, contained, except the terminal 

 rudimentary vertebrse, within the interfemoral membrane; calcaneum 

 weak; wings attached close to the base of the toes; wing and inter- 

 femoral membranes very thick and leathery. 



Dentition. Inc. ^, c. j^, p.m. g^, m. ^^ 



Upper incisors long, unicuspidate, acute; upper premolar large, exceed- 

 ing the molars in vertical extent and quite close to the canine ; last 

 upper molar consisting of a transverse plate only, first lower premolar 

 small, crushed in between the canine and second 2:'remoZar which exceeds 

 the molars in vertical extent. All the molar teeth strong with acute 

 cusps.
