of the inner margin. Crown of the head slightly but abruptly 

 raised above the flattened forehead ; muzzle flat and broad above, 

 the extremity projecting slightly beyond the lower lip, the nasal 

 tubes not much raised above the muzzle ; lower lip with a very 

 distinct median groove, as in Taphozous (Plate XX. fig. 2). 



Wings from the ankles ; tibiae very long ; calcaneum about three 

 fourths the length of the tibia ; interfemoral very deep, tail pro- 

 jecting on its upper surface by the last caudal vertebra only. 



Fur, above and beneath, dark brown, limited in a remarkable 

 manner to the body, scarcely extending in any direction upon the 

 wings, and leaving the interfemoral membrane altogether naked on 

 its upper surface. 



Upper incisors unicuspidate, small and weak, separated at their 

 bases, their cusps converging and rather close together at their ex- 

 tremities ; first upper premolar very small, in the tooth-row, scarcely 

 raised above the gum, and almost invisible without the aid of a lens ; 

 lower incisors trifid, the central pair on each side slightly overlapping 

 the others.

 with those of the next species.)

About the size of C. seychellensis ; the ears the same length as in 

 that species, but conspicuously wider above and more broadly rounded 

 off ; the form of the muzzle also quite different, viewed from beneath 

 it appears acutely conical, the summit of the cone formed by the 

 very prominent nostrils, which are also raised considerably above 

 the surface of the muzzle, the extremity of which projects much 

 beyond the lower lip ; the lower lip is not divided by a median 

 groove (Plate XX. fig. 3). 



Wings from the ankles ; calcaneum nearly as long as the tibia ; 

 tibia and interfemoral membrane much shorter than in C. seychel- 

 lensis. 



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

 the wing-membrane almost as far as a line drawn from the middle 

 of the humerus to the distal third of the femur, and upon the inter- 

 femoral as far as the point of exit of the tail ; beneath, the distri- 

 bution of the hair is similar ; a fringe of hairs, longer than in C. 

 seychellensis, margins the upper lip. 



Upper incisors as in C. seychellensis, but separated by a much
