S. SCOTOPHILUS. 261 



longer compared with the length of the head, and the terminal lobe 

 at the base of the outer margin smaller ; the outer margin is straight 

 from a point opposite the base of the tragus to the tip, not curved 

 inwards and upwards to m^eet the inner margin as in Sc. temminclcii ; 

 the tragus is conspicuously larger, and the transverse ridge on its 

 anterior surface much less defined. The thumb is much shorter. 



The fur of the body is longer, and extends ^further upon the 

 wing-membranes than in Sc. temmincJcii, especially beneath, where 

 fine hairs thinly cover the basal half of the interfemoral mem- 

 brane. 



Above olive-brown, pale yeUowish-white beneath. 



The cingulum of the upper incisor on each side is greatly deve- 

 loped in a horizontal plane backwards and outwards, forming a 

 broad shoulder on this side of the tooth, slightly raised above the 

 level of the gum. Lower incisors indistinctly trifid, and slightly 

 crowded. Lower premolars as in Sc. temmincJcii. 



Length (of an adult preserved in spirits), head and body 2"-7, 

 tail 2"-2, head 0""85, ear 0"-7, tragus 0"-35, forearm 2", thumb 

 0"-3, third finger 3"-6, fifth finger 2"-4, tibia 0"-8, foot 0"-4.

Ear-conch and tragus like those of S. borbonicus, Geoffr. ; but the 

 internal basal lobe of the ear is more rounded and its inferior 

 horizontal margin is straight, not in the least degree concave ; the 

 upper third of the oviter margin of the conch is slightly but 

 distinctly concave ; and the tragus has the narrow ridge, proceeding 

 from the base of its inner margin across its front margin, as well 

 developed as in S. temmincJcii. 



Wings to the metatarsus near the base of the toes ; last two 

 caudal vertebrae and half the third last vertebra free. 



Eur above deep chestnut, beneath yellowish white. The fur on 

 the Tipper surface is short and does not extend anywhere upon the 

 membranes, terminating by a well-defined line, and not extending 

 posteriorly as far as the root of the tail ; beneath, the wing- 

 membrane is thinly covered as far as a line drawn from the elbow 

 to the knee-joint, and a band of fur passes outwards, posterior (o
