foot ; tail of four vertebrse, scarcely half the length of the inter- 

 femoral membrane, on the upper surface of which the last short 

 vertebra projects. 



The face is very hairy ; the nose-leaf is dusted over with fine hairs, 

 most abundant on the horseshoe and along the edges ; the sides of 

 the muzzle bristle with hairs, which form a short fringe along the 

 upper lip ; the humerus and the muscular part of the forearm are 

 covered with long hairs, and short hairs cover the remaining part 

 of the forearm to the carpus, becoming much longer and denser on 

 the metacarpal bone of the thumb, fine short hairs also extending 

 to the base of the claw of the thumb and along the whole extent of 

 the middle finger, also upon the legs and backs of the feet to the 

 base of the claws. 



Incisors as in Vampyrus spectrum, but not crowded ; the first 

 lower premolar exceeds the third as much as the third exceeds the 

 second.

Head as in Sell, hirsutum, the horseshoe-shaped portion of the 

 nose-leaf narrower, in width equal to half the length of the whole 

 leaf, its front edge continuous with the underlying integument and 

 separated by a narrow space from the margin of the lip ; the erect 

 lancet-shaped leaf broader in its broadest part than the horseshoe, 

 abruptly narrowed and terminating in a very acute point ; front 

 surface of the leaf smooth, without a longitudinal ridge, and naked ; 

 ears as long as the head, united by their inner and posterior sides by 

 a band 0"'12 deep ; form of the ear-conch and tragus as in Sch. hir- 

 sutum (Plate XXIY. fig. 5). 



Metacarpal bone of the thumb longer than the phalanx, enclosed 

 in the antebrachial membrane ; metacarpal bones of the third, fourth, 

 and fifth fingers equal, the bones of the fourth finger equal respec- 

 tively to those of the fifth ; the first phalanx of the middle finger 

 very slightly shorter than the second. 



Wings from the tarsus ; calcaneum slightly longer than the foot ; 

 tail and interfemoral membrane as in Sch. hirsutum. 



The fur of the body scarcely extends upon the membranes, which, 

 with the extremities, are almost quite naked.
