forming a straight line to the tip : tragus moderately long, acutely 

 pointed ; inner margin straight, outer slightly convex upwards, with a 

 small rounded lobe at the base (Plate XIX. fig. 4, head, enlarged). 



Tail wholly contained within the interfemoral membrane. Wings 

 from the base of the toes. 



Fur, above, dark brown, the extreme tips paler and shining ; 

 beneath, much darker, almost black for three fourths the length of 

 the hairs, the remaining portion ashy. Above the face is densely 

 covered, the long hairs concealing the eyes, but the anterior half 

 of the muzzle is nearly naked ; on each side of the muzzle two or 

 three small glandular wart-like elevations may be seen through 

 the hairs. The ears are quite naked anteriorly, posteriorly their 

 bases only are covered. On the wing-membrane the fur of the 

 back extends as far as a line drawn from the junction of the 

 proximal and middle thirds of the humerus to the commencement 

 of the distal third of the femur ; on the interfemoral membrane it 

 ceases abruptly at the end of the second caudal vertebra. Beneath, 

 the fur extends upon the wing-membrane as far as a line drawn 

 from the elbow to the knee-joint; the interfemoral membrane is 

 covered at the root of the tail, and three fourths of the remaining 

 part is very thinly clothed with the short hairs arising from the 

 transverse dotted lines. 



Incisors on each side parallel and acutely pointed ; inner incisors 

 longest, with a small acutely pointed talon near their extremities 

 on the outer side. In the lower jaw the second premolar is small, 

 but distinctly visible, standing in the tooth-row ; in the upper jaw 

 the space between the canine and third premolar is small, and the 

 second premolar is very minute, placed interiorly, in the angle 

 between the first and third premolar, and with difiiculty distin- 

 guishable even with the aid of a lens.
