Head very slightly raised above the face-line ; ears moderately 

 long, laid forwards the tips extend quite to the extremity of the 

 muzzle, the inner margin forms a regular arc of a circle from the 

 base to the tip ; the tip is shortly rounded ofi' ; and the upper third 

 of the outer margin is flat or concave, owing to the abrupt convexity 

 of the succeeding middle third ; tragus about half the length of the 

 ear, the extremity straight, not curved outwards ; the inner margin 

 is straight, the outer has a very distinct triangular rounded lobe at 

 the base, then becomes regularly slightly convex upwards, reaching 

 its greatest width about the middle, and terminating in an acute point. 



Wings from the metatarsi ; calcaneum extending more than three 

 fourths the distance between the ankle and the taU. 



The face is sparingly covered with hair in front of the ears. The 

 small labial glands are thinly clothed by some long straight hairs. 

 On the dorsal surface the base of the iuterfemoral membrane as far 

 as a line drawn between the centres of the tibia is covered; the 

 tibiae and the remaining part of the iuterfemoral naked. 



Above, the hairs are dark at the base, with reddish-brown extre- 

 mities ; beneath, similar at the base, but with white extremities. 



The upper incisors are equal in size, and have strongly diverging 

 cusps ; the second upper premolar stands in the tooth-row, is very 

 small, not one third the size of the first premolar, and its summit 

 very slightly exceeds the cingulum of the first molar. 



Length (of an adult J preserved in alcohol), head and body l"-9, 

 tail l"-7, bead 0"-65, ear 0"-55, tragus 0"-28, forearm l"-45, thumb 

 0"-35, third finger 2"-4, fifth finger l"-9, tibia 0"-6, foot 0"-4.
