 a, b, c (1870). 



Head broad and flat ; muzzle thick ; nostrils opening sublateraUy, 

 without intervening emargination ; ears moderate, with rounded 

 tips, inner margin convex, with a small lobe at the base, outer edge 

 with a shallow but wide emargination beneath the tip, then convex, 

 and again emarginate opposite the base of the tragus, terminating 

 by forming a small lobe midway between the base of the tragus and 

 the angle of the mouth ; tragus obtusely pointed, broadest slightly 

 below the middle, inner margin straight, outer margin with a small 

 rounded lobe at the base, succeeded by a shallow emargination, then 

 convex upwards to its junction with the inner margin. 



Toes longer than half the whole foot. Tail of eight vertebrae, the 

 last vertebra free. 



The fur of the head and body is moderately long and dense ; an- 

 teriorly it passes forwards upon the face in front of the eyes as far 

 as the commencement of the glandidar prominences of the upper 

 lip, from which only a few long hairs arise; the portion of the 

 face about the eye and in front of the base of the inner margin of 

 the ear is also naked ; but the space between the base of the tragus 

 and the angle of the mouth is covered with long hair. In front the 

 ears are naked, except where a few very short hairs appear on the 

 upper and inner sides of the conch ; posteriorly the fur of the head 

 encroaches on their bases, but more than one half of their posterior 

 surfaces is completely naked. On the upper surface the fur of the 

 back extends upon the wing-membrane as far as a line drawn from 

 the junction of the proximal and middle thirds of the humerus to 

 the middle of the femur ; posteriorly it extends as far only as the 

 root of the tail; and the interfemoral membrane has but a few very 

 fine hairs dusted over its anterior surface as far as the end of the 

 second caudal vertebra. Beneath, the distribution of the fur on the 

 wing-membranes is similar to that on the upper surface, but some- 

 what more extended ; a line of fine thinly spread hairs passes out 

 along the posterior margin of the humerus and forearm to the 

 carpus ; posteriorly, the fur of the abdomen covers the root of the 

 tail only, and three fourths of the surface of the interfemoral mem- 

 brane is occupied by a few thinly spread, very fine, minute hairs. 



Fur, above, dark brown with greyish tips ; beneath, light greyish 

 brown for two thirds the length of the hairs, the remaining portion 

 ashy.
