Male. — Head rather small, ovate, convex above, with the 

 muzzle moderate, or rather short ; the space anterior to the 

 eye tumid with sebaceous glands ; the face hairy, but the space 

 about the eyes nearly bare. The snout of moderate breadth, 

 bare, dusky, at the tip a little emarginate or repand, and a 

 twelfth and a quarter of an inch in breadth. Nostrils lateral, 

 tumid, transversely oblong, with a protuberance from the upper 

 edge. Mouth opening to beneath the eyes. Owing to the 

 partially bared space in which they are situate, rather than to 

 their size, the eyes are somewhat conspicuous, globular, black ; 

 the eyelids with an elliptical aperture, the upper ciliated, but 

 not on the margin ; and at its anterior part a small prominence 

 bearing a tuft of long hairs. 



The ears about one-third shorter than the head if measured 

 direct from the base of the tragus, or about the same length 

 if measured alongthe outer margin, ovate, somewhat triangular, 

 directed outwards and forwards, obtuse ; the inner margin com- 

 mencing a little above the eye, and convex ; the outer with a 

 deep sinus in its upper half, and four transverse ridges, but 

 in its lower half convex, forming a rounded lobe, and at the 

 base having a small rounded opercular lobe, externally hair3% 

 Tragus rather inconspicuous, half the length of the ear, linear- 

 oblong, slightly curved inwards, tapering towards the end, which 

 is narrow, but not acute, being rather obtusely pointed. It 

 has a small angular process or lobelet at the base externally* 



The neck short ; the body broad anteriorly, narrow behind. 

 Wings long, of moderate breadth ; the cubitus rather longer 

 than the tail ; the membranes thin and bare. The poUex 

 rather stout, though much compressed, of three joints, with 

 the claw extremely compressed, moderately curved, edged be- 

 neath, broad at the base, acuminate. The index of two 

 joints, the last cartilaginous ; the other digits of three joints. 

 The hind limbs rather long, toes rather stout, nearly equal, 

 compressed, the outer shortest ; the claws small, compressed, 

 moderately curved, thin-edged, broad at the base, acuminate. 

 The spur half an inch long. The tail long, and extending 

 a twelfth of an inch beyond the membranes. 



The fur rather long, dense, very soft, inclining to silky
