the sides of the face, increasing the width of the muzzle. Ears 

 shorter than the head, triangular, rounded at the tips ; outer margin 

 straight, without emargination. Tragus small, and broadly rounded 

 off at the tip, attaining its greatest breadth about the middle of 

 inner margin ; outer margin convex, inner straight or slightly 

 concave, above the base of the outer margin a very distinct acutely 

 angular lobule. 



Wings to the base of the claws ; postcalcaneal lobe close to the 

 ankles, triangular; tail whoUy included, except the extreme tip, 

 within the rnterfemoral membrane. 



Wing and interfemoral membranes pure white ; ears dark brown ; 

 fur on the upper surface dark brown, the forearm, legs, and taU of 

 the same colour ; beneath, pure white, the base of the fur dark, the 

 humerus, forearm, and legs white ; feet, above and beneath, dark 

 brown. 



Muzzle in front of the eyes nearly naked. On the upper and 

 lower surfaces the fur extends for a short distance only upon the 

 wing-membranes. Above, the base of the interfemoral only is 

 clothed ; beneath, it is covered with very short hair, as in V. mibri- 

 catus. 



Outer incisors very small and acutely pointed, placed at the outer 

 and anterior side of the base of the inner incisors, which are nearly 

 twice their length, and have a small prominent external cusp ; 

 lower incisors at right angles to the direction of the jaws. 



Length (of an adult c? preserved in spirits), head and body l"-5, 

 tail l"-05, head 0"-55, ear 0"-45, tragus 0"-18, forearm 1"-15, thumb 

 0"-2, third finger l"-9, fifth finger l"-4, tibia 0"-45, foot 0"-25.

The face is concave between the anterior margins of the inner 

 sides of the ears ; the muzzle not very obtuse, but the glandular 

 prominences so developed upwards as to cause a shallow furrow 

 between them on the muzzle. Ears short and very funnel-shaped, 

 owing to the great convexity of the middle third of the outer 

 margin ; inner margin very convex forwards in its lower two 

 thirds ; upper third of the outer margin very concave, owing to the 

 convexity of the middle third, tips short and narrowly rounded-off ; 

 tragus rather broad, maintaining the same breadth from the base to 

 a point opposite the upper third of the inner margin, where the 

 outer margin curves inwards to join the inner margin ; at the base 

 of the outer margin a very shallow triangular lobe, not succeeded by 

 an emarghiation, inner margin straight (Plate XII. fig. 2). 



Wino-s to the base of the toes ; postcalcaneal lobe long, and 

 convex^ehhid (less distinct in young individuals) ; tip of tail free. 



Above black, the extreme points of the hairs ashy or greyish ;
