218 VESPERTILIONIDJS. 



the outer margin correspondingly convex, meeting the inner margin 

 at an acute point directed inwards, forming the superior comu of 

 the crescent. The tragus reaches its greatest width slightly below 

 the middle of the inner margiu. Glandular prominences between 

 the eyes and nostrils well developed, causing a slight hoUow on the 

 muzzle above. 



Wings to the base of the toes ; postcalcaneal lobe small, indi- 

 stinct ; tip of tail projecting ; toes rather more than half the length 

 of the foot, armed with feeble claws. 



The distribution of the fur upon the wing- and interfemoral 

 membranes is similar to that in V. abranius. 



Above dark brown ; beneath similar, with slightly ashy tips. 



Upper inner incisors long, bifid, slanting considerably inwards ; 

 outer incisors ujiiouspidate, acutely pointed, half the length of the 

 inner incisors, but less than half their transverse diameter. 



Lower incisors slightly crowded, equal in size, and distinctly tri- 

 fid. Second upper premolar very close to the canine ; first upper 

 premolar very small, its summit scarcely elevated above the gum, 

 crushed in between the canine and second premolar, and not visible 

 from without. Pirst lower premolar acutely pointed, equal to three 

 fourths the second premolar ; second premolar nearly equal to the 

 canine in vertical extent.

Muzzle broad and flat above, the glandular prominences on each 

 side well developed, increasing the width of the muzzle ; nasal ori- 

 fices openiiag almost on a level with the front surface of the muzzle, 

 without intervening emargmation. Ears broad, triangular, broadly 

 rounded off above ; the outer margin straight above for nearly half 

 its length, then slightly convex to the base, terminating midway 

 between the base of the tragus and the angle of the mouth in a 

 small lobe ; tragus broad, reaching its greatest breadth above the 

 middle of the inner margin, at the base of the outer margin a distinct 

 triangular lobule, succeeded above, immediately below the middle
