The muzzle is of very moderate length and substance, and rather 

 pointed ; the nostrils are rather small, near together, and directed 

 sublaterally. The end of the nose, between the noitrils, is somewhat 

 emarginate. Tiie ears are short, ovoid, and very rauch rounded at 

 their tips, which are directed outwards. Towards the base of the 

 front edge of the ear is a lobular projection, occasioned by a notch in 

 the margin immediately under it, quite at the base of the ear, and 

 (tontiguous to the tragus. The outer margin is continued forward 

 along the side of the face toward the angle of the mouth, and ends 

 near to it, in the form of a moderately developed lobe. The tragus 

 is narrow at its base, from which it expands evenly and rather ra- 

 pidly for half its length, where, making a conspicuous angle, it 

 slopes invvards, and comes to a narrow but rounded point, its inner 

 margin all the time maintaining a nearly straight line, exceptiug near 

 the tip, where it has a decided inward curvature. The outer mar- 

 ginai angle, already mentioned, is something more than a simple 

 angle, being, in fact, a rounded projection from the crooked edge of 

 the tragus. 



The wing-membranes extend to two-thirds of the distance be- 

 tween the extremity of the tibia and the base of the toes. 



The face is more or less covered with hair on all parts, the end 

 of the nose and the margins of the lips only being naked. On the 

 forehead the fur is very thick, and approaches nearly to the end of 

 the nose. Immediately in front of the eye, is a tuft of stiff hairs.
