 the upper lip though rather small ; the erect lanceolate leaf equals 

 in length nearly double the width of the horseshoe, and is as broad 

 as it at its base, its front surface is marked by a strong and 

 broad raised ridge ; lower lip with a central circular wart sur- 

 rounded by small warts ; thumb short, the metacarpal bone equals 

 the first phalanx in length ; tail produced to, and terminating exactly 

 at the margin of, the interfemoral membrane, which forms a straight 

 line between the extremities of the long calcaaea ; calcaneum 

 longer than the tibia and equal to half the forearm in length ; feet 

 very large. 



Fur, above, soot-brown, slightly paler beneath ; wing-membrane 

 naked. 



Middle upper incisors unicuspidate, converging forwards and in-

 (Plate XXIV. fig. 2) ; first upper premolar scarcely one third the 

 size of the second, vnth an oblique cusp directed forwards ; lower 

 incisors equal, in a semicircle, summits slightly pectinate ; first and 

 second lower premolars nearly equal in cross section, the second ex- 

 ceeding the first in vertical extent.
