Synopsis of the Species. 



a. Tail very short; interfemoral membrane nearly 



naked ; forearm l"-25 1. L. cartdifera, p. 506. 



b. Tail absent ; interfemoral membrane well 



covered ; forearm l"-6 2. L. loiedii, p. 507. 



1. Lonchoglossa caudifera. 



Glossopbaga caudifer et ecaudata, Geoffrey, Mem. du Musium, iv. 

 p. 418, pis. xvii. & xviii. fig. b (1818) (vide Peters, MB. Akad. 

 Berl. 1868, p. 364). 



Nose-leaf and ears as in Monophyllus redmani, the nose-leaf 

 slightly shorter and more pointed, and the muzzle longer. 



Thumb shorter than the foot, which equals three fourths the tibia 

 in length. Wing-membrane extending to the distal extremity of the 

 tibia. Tail very short, scarcely distinguishable in dried skins ; in- 

 terfemoral membrane deeply concave behind, the emargination ex- 

 tending as high as a line drawn between the knees ; calcaneum 

 about half as long as the foot. 



Fur dark brown on the surface above, but the greater part of the 

 hairs pale whitish buff ; beneath light brown. The muscular part 

 of the forearm is covered with short fur, but the membranes and re- 

 maining parts of the extremities are nearly naked ; the interfemoral 

 membrane has a few fine hairs, forming a thin fringe along its free 

 margin.
