outer margin convex above, concave opposite the base of the tragus, 

 and terminating in a large slightly convex lobe, as in S. canina ; 

 tragus with straight sides and broadly rounded-off extremity, the 

 outer and iipper margins irregularly toothed. Muzzle and nostrils 

 as in the preceding species. 



Wing-sac as in S. canina ; wings from the tarsus or metatarsus ; 

 free margin of the interfemoral membrane straight behind between 

 the extremities of the calcanea. 



Fur dark brown above, slightly paler beneath ; wing-membrano, 

 between the body and a line drawn from the elbow to the knee, 

 white, translucent, with small black dots corresponding to the 

 position of hairs, the remaining parts of the integuments dark 

 brown. On the upper surface the wing-membrane is thinly covered 

 as far as a line drawn from the middle of the humerus to the knee, 

 and the interfemoral as far as the point of exit of the tail ; beneath, 

 as far as a line drawn from the proximal third of the humerus to 

 the junction of the thigh with the body ; the under surface of inter- 

 femoral clothed with short fine hairs. 



Dentition as in the preceding species.

Type in the collection of the Berlin Museum. 



The following genus has been founded on the Emhallonnra bremrostris of 

 Wagner, the type of which consists of a single badly-preseryed female specimen 

 in the Vienna Museum, from which it is impossible to determine whether a 

 wing-sac exists or not.

Ears much shorter than the head ; ear-conch triangular, with broadly rounded- 

 off vertical angle ; inner margin faintly convex ; outer margin straight, emarginate 

 opposite the base of the tragus, and terminating in a convex lobe midway be- 

 tween the tragus and the angle of the mouth : tragus erect, maintaining almost 

 the same breadth from the base of the inner margin to the tip, which is abruptly 

 truncated ; outer margin with a small lobe near the base. 



"Wings from the metatarsus ; caleaneum shorter than the tibia. 



Above reddish brown, with paler extremities, beneath similar, but paler ; the 

 hair at the base of the ears and on the middle of the occiput whitish, and that 

 of the shoulders near the spine pure white at the base. 



The skull is much shorter in the facial portion than in any of the preceding 

 species the frontal bones are less flattened, and the crown of the head more 

 elevated The teeth are also larger, and in consequence of this, and of the 

 shortness of the facial portion of the skuU, the small first upper premolar almost 

 fills up the space between the canine and the second premolar ; upper incisors 

 Terv smaU and feeble, lower incisors trilobate.
