extremity ; outer incisor very short, close to the base of the inner 

 moisor and in a plane slightly anterior to it ; lower incisor at right 

 angles to the direction of the jaws, overlapping, trilobate ; the single 

 upper premolar long, close to the canine; first lower premolar 

 scarcely half the length of the second premolar.

The above are the dimensions of the largest specimen in the 

 collection, which does not appear quite full-grown. In Tomes's 

 measurements of this species the length of the forearm is given as 

 1 '-55, and that of the tibia as 0"-65.

About the size of V. serotinus. Ears shorter than the head, as in 

 V. capensis ; tragus as in the Serotine, slightly narrower ; head flat ; 

 muzzle nearly naked ; tail long, the last caudal vertebra quite free ; 

 no trace of a postcalcaneal lobe ; wings from the base of the toes. 

 Fur moderately long and woolly, much faded in the single type 

 specimen, but apparently similar to that of the Serotine. 



Skull like that of V. serotinus, but the teeth are very different. 

 The inner upper incisor long, acutely pointed, and uniaisjiidate, the 

 outer incisor very small, with a short, slender, single cusp arising 

 from the broad base which lies between the inner incisor and the 

 canine, not slightly in front of the outer side of the inner incisor as 

 in V. serotinus! ; the single upper premolar close to the canine, last 

 upper molar equal to half antepenultimate molar. Lower incisors 

 as in V. serotinus. The first lower premolar smaller and more 

 crushed in between the canine and the second premolar, and 

 elevated by its base above the bases of the other teeth. Base of the 

 skuU as in V. serotinus, but the tympanic bullae are larger. 



Length (of the type specimen), head and body about 2"-G, tail 2", 

 head 0"-85, ear 0"-6, tragus 0"-3, forearm 2", thumb 0"-4 ; third 

 g^o-er — metacarp. l"-7, 1st ph. 0"-65, 2nd ph. 0"-85 ; fifth finger — 

 metacarp. l"-65, 1st ph. 0"-45, 2nd ph. 0"-3; tibia 0"-8, foot 0"-45.
