482 ruyLLOSTOMiD-E. 



Wing-membrane extending to the tarsus ; oalcaneum three fourths 

 the length of the foot ; interfemoral membrane large, slightly con- 

 cave between the ends of the calcanea ; tail as long as the thumb, 

 of four short vertebrae contained in the upper surface of the inter- 

 femoral membrane. 



Fur, above, dark reddish brown, the base of the hairs whitish, the 

 extreme tips slightly ashy ; beneath, paler brown to the base of the 

 hairs, the extremities ashy. 



Upper middle incisors large, slightly notched, occupying by their 

 bases nearly the whole space between the canines ; outer incisors 

 very small, scarcely visible without a lens, not raised above the gum ; 

 lower incisors equal, not crowded (Plate XXVI. fig. 4) ; first upper 

 premolar about half the size of the second, the cusp directed slightly 

 obliquely forwards and downwards, on the whole like that of Phyl- 

 lostoma hastatum ; m.olars acutely tubercular, with well-defined W- 

 shaped cusps ; first lower premolar three fourths the third in verti- 

 cal extent, but exceeding it in cross section ; the second premolar 

 scarcely as large as one of the lower incisors, internal to the tooth- 

 row, and not visible from without (Plate XXVI. figs 4a, 4 b). With 

 the exception of this small second lower premolar, the teeth are very 

 similar to those of Phyllostoma hastatum.

Muzzle abruptly narrowed in front of the eyes ; chin with a 

 V-shaped space margined by small warts ; nose-leaf narrow in front, 

 bound down to the muzzle ; ears separate ; tail perforating the in- 

 terfemoral membrane and appearing upon its upper surface ; wing-

 the metacarpal bone.
