6. VESPERUGO. 243 



The next subgenus approaches ScotopMlus in the single pair of 

 unicuspidate upper incisors placed close to the canines, but in all 

 other characters agrees with Vesperugo. The first lower premolar 

 is not crushed in between the adjoining teeth, as in the species of 

 ScotopMlus, but is slightly inclined outwards in the manner so cha- 

 racteristic of Vespemgo. 



Inc. -g-, p7n. 2112 ! ^^^ sinffle upper incism; on each side, close to the canine, 

 as in Scotophilus ; premolars and molars as in the Subgenus Vespe- 

 rugo ; Jirst tninute upper premolar deciduous ; tJie two central lower 

 incisors larger than the other incisors ; postcalcaneal lobe distinct. 

 Hab. Ethiopian and Oriental Regions. Subgenus Scoxozous. 



48. Vesperugo dormeri. 



Scotozous dormeri, Dobson, P. Z. S. 1875, p. 873. 



Vesperugo dormeri, Dobson, Monogr. Asiat. Cliiropt. p, 118 (1876). 



Crown of the head scarcely raised above the face-line, glands 

 between the nostrils and eyes well developed, but not causing a 

 depression between them on the muzzle ; nostrils opening sublate- 

 rally, the space between divided in the centre by a narrow vertical 

 ridge passing downwards to the lip as in Vespervc/o pipistrellus : 

 ears shorter than the head, triangular, with rounded tips ; upper 

 third of the outer margin of the ear faintly concave, then gradually 

 convex, again slightly concave opposite the base of the tragus, and 

 terminating in a rounded lobe below the eye, on a level with the 

 angle of the mouth. Tragus with a small triangular lobe near the 

 base of the outer margin ; outer and inner margins parallel as far 

 as the upper third of the outer margin, where the outer margin 

 slopes suddenly upwards and inwards, meeting the inner margin at 

 an angle. 



Thumb armed with a strongly curved claw ; postcalcaneal lobe 

 distinct, triangular ; tip of tail projecting ; wings from the base of 

 the toes ; foot rather large, first toe nearly equal to the others in 

 length. 



Fur above brown, the extreme tips ashy; beneath darker brown, 

 the terminal third of the hairs white. 



A single large and acutely pointed unicuspidate incisor on each 

 side above, directed forwards and inwards ; this tooth almost touches 

 the canine by its base ; but its summit is closer to its fellow of the 

 opposite side, owing to its direction inwards ; from the outer side 

 of its cingulum a very small spur projects. Second upper premolar 

 large, equal to three fourths the canine in vertical extent, and 

 placed close to it ; in the small triangular space inside, between it 

 and the canine, a minute premolar may be seen with the aid of a 

 lens, not visible from without. Posterior upper molar equal to half 

 the 'antepenultimate molar. Lower incisors crowded ; middle inci- 

 sors slightly larger than the others, all distinctly trifid ; lower 

 canines without a cusp from inner margin of cingulum. First 

 lower premolar shorter than the second premolar, but in transverse
