Ears much shorter than the head ; laid forwards the inner margin 

 of the couch extends slightly fiu-ther than halfway between the eye 

 and end of the muzzle ; inner margins less than one tenth of an 

 inch apart at their bases, uniting on the muzzle in a prominent 

 rounded ridge, which ends abruptly at a short distance behind and 

 above the nostrils ; inner and outer margins of the ear-conch con- 

 tinuous, forming almost an arc of a circle ; ear-keel short, thickened, 

 but not expanded beneath, clothed posteriorly with short hairs ; an- 

 titragus circular, with a narrow base, as in M. rufus, but thickened 

 and expanded above and posteriorly, so that its very convex superior 

 and posterior margin projects backwards considerably beyond its 

 base ; tragus very smaU, as in M. rufus, with a minute projection 

 at the outer side of its base ; muzzle very obtuse in front, nearly 

 vertically truncated ; nostrils directed forwards and slightly out- 

 wards, connected above by an ill-defined ridge, ■which does not ex- 

 tend downwards between them ; the wide space between the nostrils 

 and the margin of the upper Up occupied by a quadrilateral patch 

 of thickly spread short hairs, the sides of the muzzle almost naked. 

 A large gular sac in male, as in M. rufus (Plate XXI. fig. 2). 



Wings from the ankles ; interfemoral membrane deep, including 

 quite three fourths of the tail. 



Pur moderately long, but conspicuously longer than in M. rufus ; 

 dark brown above, paler beneath ; the base of the hairs whitish on 

 both surfaces. On the upper surface a band of short fur, commencing 

 in a narrow line at the beginning of the middle third of the fore- 

 arm, increases in width outwards so as to cover the proximal third 

 of the fifth metacarpal bone and the fourth of the fourth metacarpal, 

 occupying also the portion of wing-membrane between; beneath, 

 the wing-membrane, between the humerus and femur, is thickly 

 covered, and a band of fur 0"-3 wide extends outwards behind the 

 forearm to the fifth metacarpal bone and to the wing-membrane 

 beyond it, covering half the bone. 



Upper incisors touching by their inner margins, their summits 

 slightly separated ; the broad base of each tooth nearly fills up the 

 interval between the canine and the centre of the intercanine 

 space, and develops externally a small basal cusp which touches the 

 cingulum of the canine ; lower incisors very small, in the space in 

 front of the projecting cingula of the closely approximated lower 

 canines, the middle pair bifid, the outer incisors very small and
