Leiponyx biittikoferi , n. sp. 



Ear longer than the muzzle (the distance between the 

 tip of the nose to the foremost corner of the eye). Ear- 

 conch with a rounded tip , the outer margin in its upper 

 part concave, convex further on, inner margin slightly 

 curved. Shoulder-glands absent in the female, the single 

 specimen we possess. 



The palate-ridges are seven in number; the first four 

 are undivided ; the first is nearly straight and placed be- 

 tween the canines , the second is slightly curved and placed 

 immediately behind the first premolars, the third ridge 

 is broader than the second and unites the second premo- 

 lars ; the fourth again is more arched and unites the space 

 between the two molars on each side. The three remain- 

 ing ridges form oval elevations on each side resembling 

 those in Epomophorus coniptus. They are succeeded by 

 ill-defined semicircular toothed lines similar to the same 

 parts in Epomophorus franqueti. 



The four unicuspidate upper incisors are placed at a distance 

 from the canines , in pairs , with a rather wide space be- 

 tween those pairs. The foremost incisors are the smallest. 

 The lower incisors are also unicuspidate and nearly equal in
