Muzzle conical, and narrower than in the preceding species ; end 

 of nose prominent ; glands on the sides of the muzzle between the 

 eyes and nostrils forming rounded elevations not engaging the lip ; 

 ears rhomboidal, but longer than broad ; upper third of the outer 

 margin of the conch straight, middle slightly convex, deeply emar- 

 ginate opposite the base of the tragus, terminating in a rather deep 

 lobe, whereof the front margin is faintly concave ; inner margin of 

 the tragus straight, except immediately beneath the subacute tip 

 which bends inwards, outer margin forming a strongly projecting 

 angle nearly opposite the base of the inner margin. 



Wings from the metatarsus, close to the base of the toes ; a nar- 

 now but distinct postcalcaneal lobule; extremity of the tail not 

 projecting. 



Wing-membrane naked above, except a small patch of short hairs 

 at the base of the thumb and near the elbow ; beneath, a narrow 

 band of fur extends outwards behind the forearm, and a few hairs 

 appear in the angles between the fifth and fourth, and fourth and 

 third fingers ; the antebrachial membrane is covered with a few 

 hairs only. The fur of the back extends rather thickly upon the 

 wings as far as a line drawn from the middle of the humerus to the 

 knee ; behind, more than three fourths of the interfemoral is covered, 

 also the legs and feet and the adjoining wing-membrane are clothed 

 with short hair. Beneath, the wings are similarly clothed, but the 

 base of the interfemoral, as far as the end of the second caudal 

 vertebra, is alone covered. 



Above, dark at the base of the hairs, then light bufiF, the extre- 

 mities red ; beneath, the basal half is dark brown, the terminal half 

 briUiant red ; the fur clothing the interfemoral membrane and the 

 posterior extremities bright red throughout. Wing-membranes 

 black, slightly paler along the thumb, the index and the middle 

 fingers.
