Ears broad, as long as the bead, laid forwards the tips extend 

 to a point midway between the eye and the end of the muzzle ; 

 inner margins conjoined on the forehead by a low vertical band, 

 projecting in front slightly beyond the eye ; outer margin ter- 

 minating abruptly between the eye and the upper lip, and at a 

 point slightly in front of the eye, so that a line drawn from the 

 most anterior part of the inner margin to the termination of the 

 outer margin, above the mouth, passes in front of the eye ; the inner 

 margin is regularly convex and slants much backwards, the tip 

 shortly truncated ; the outer margin is concave beneath the tip, 

 with a small well-defined circular projecting lobe at the junction of 

 the upper and middle thirds, beneath this straight to the outer end 

 of the terminal lobe. Tragus very broad opposite the base of the 

 inner margin, suddenly narrowed from without inwards opposite 

 the middle of the straight inner margin, attenuated thence upwards 

 to the tip, which is subacutely pointed ; the extremity of the tragus 

 reaches as high as the small circular lobe projecting from the outer 

 margin of the ear. 



Wings to the base of the toes ; toes more than half the length of 

 the foot ; postcalcaneal lobe narrow ; calcaneum extending half the 

 distance between the foot and end of tail ; tail as long as the head 

 and body, projecting slightly beyond the membranes. 



On the upper surface the fur of the body extends as far as a line 

 drawn from the middle of the humerus to the knee-joint ; on the 

 interfemoral long, extending backwards triangularly as far as half 

 the length of the tail ; beneath, the wing-membrane is covered so 

 far as a line drawn from the elbow to the knee, and the interfe- 

 moral is clothed with long white hairs to a somewhat less extent 

 than upon the upper surface. Fur, above and beneath, intensely 

 black, the tips indistinctly greyish, the light shade more apparent 

 beneath. On the base of the interfemoral beneath the hairs are 

 white. 



Upper incisors sloping inwards and forwards ; upper inner inci- 

 sors long, with a second cusp near the extremity posteriorly and 

 externally ; immediately posterior and external to this cusp the small 

 unicuspidate acutely-pointed outer incisor is placed. The first 

 upper premolar minute, in the inner angle between the closely ap- 

 proximated canine and second premolar. First lower premolar 

 scarcely more than half the vertical height of the second premolar, 

 and in transverse diameter not half its size.
