Wiiig-membrane attached to the side of the foot near the base 

 of the toes ; postcalcaneal lobe narrow ; extremity of the tail pro- 

 jecting. 



On the upper surface the fur of the body is almost wholly con- 

 fined to the body, scarcely extending in any direction upon the wing- 

 membrane ; beneath, the wing-membrane is covered with fine hairs 

 as far as a line drawn from the elbow- to the knee-joint ; the inter- 

 femoral is naked, except where a few scattered hairs appear at the 

 base of the tail. 



The colour of the fur varies very much in different individuals, 

 and according to season and age. It appears to vary, however, 

 within certain limits. Generally dark olive-brown above, and 

 reddish or yellowish-white beneath ; in some specimens deep chest- 

 nut throughout, or the inferior surface is bright chestnut or rich 

 canary-colour. 



In fully adult and aged animals the skull is thick, with prominent 

 crests ; the occipital and sagittal crests form at their junction a thick 

 projecting process, from which the skuU slopes evenly downwards 

 and forwards to the end of the nasal bones in front (Plate XX. 

 figs. 6, 6a) ; occiput concave, with prominent occipital crest ; facial 

 bones much shortened in front of the infraorbital foramina, which 

 are large and well defined ; the bony palate very narrow behind the 

 last molar, extending backwards as far as the middle of the zygo- 

 matic arches ; basioecipital between cochleae broad ; cochleae partially 

 concealed by the tympanic bullae ; paroccipital and mastoid processes 

 well developed, prominent. 



Length (of an adult c? ), head and body 3"'l, tail 2"-l, head 1", 

 ear 0"-65, tragus 0"-38x0"-l, forearm 2"-3, thumb 0"-38, third 

 finger 3"-65, fifth finger 2"-5, tibia 0"-9, foot 0"-45. 



Specimens of this species vary as much in length as they do in 

 colour. Those from the islands of the Malay Archipelago are gene- 

 rally smaller than those from the continent of Asia.
