Muzzle obtuse, glandular prominences well developed, causing a 

 considerable depression between them and the crown of the head, 

 not easil}' perceived, however, in the living animal, owing to the 

 length of the fur in this situation ; the nostrils open almost directly 

 forwards. Ears broadly triangular, rounded at the tips ; a concavity, 

 occupying rather more than one third of the upper part of the outer 

 margin, commences beneath the broadly rounded summit of the ear; 

 the outer side then becomes abruptly convex, again slightly concave 

 opposite the base of the tragus, and terminates in a convexity which 

 supports about the middle a smaU rounded lobe directed upwards. 

 The tragus is rounded off towards the inner margin above, the outer 

 margin convex and sloping inwards in its upp)er third, the inner 

 margin straight or slightly concave ; the outer margin has a trian- 

 gular lobule above the base, not succeeded by an emargination, and 

 then becomes parallel to the inner margin. 



Feet small ; wings to the base of the toes ; postcalcaneal lobe 

 well developed, rouuded, placed on the calcaneum at a distance 

 from the end of the tibia equal to half the length of the foot; last 

 rudimentary caudal vertebra free. 



The head and face, as far as the glandular prominences of the 

 muzzle, are densely covered with hair ; in front the muzzle is 

 clothed with short fur, interspersed with a few long straight hairs. 

 The body is densely covered with rather long fur, black at the base 

 and for half the length of the hairs, the remaining half light brown, 

 or, in specimens inhabiting sandy districts, ashy, causing the fur to 

 appear almost white throughout; beneath, about three fourths of 

 the length of the hairs is black, the remaining part to the tips more 

 or less ashy, sometimes with a yellowish or canary-colour tinge, 

 especially during the breeding-season ; in others the colour of the 

 fur beneath scarcely differs from that above. 



On the upper surface the fur of the body extends thickly upon 

 the wing-membrane as far as a line joining the middle of the 

 humerus and the knee-joint ; on the interfemoral it extends nearly 

 as far as a line drawn lietween the ankles when the tail and inter- 

 femoral membrane are extended ; beneath, the wing-membrane is 

 covered as far as a line joining the elbow- and knee-joints ; the fur 

 of the body passes upon the interfemoral at the root of the tail 

 only and along the inner sides of the thighs, about half the remain- 

 ing portion is covered with very fine short hairs, extending prin- 

 cipally along the tail. 



The upper incisor on each side is long and bifid, the lesser cusp 

 external ; the outer incisor as long or slightly longer than the outer 

 cusp of the inner incisor in fully adult individuals ; in older specimens
