208 VESPEETILIONID^. 



margin of the ear-conch terminates under the jaw, which has caused 

 the describer, Dr. Peters, to make it the type of a new subgenus, 

 Marsipolcemus. In the prolongation of the ear-conch, in the form 

 of the tragus, and in dentition it resembles the African species of 

 Chalinolobus.

Crown of the head very flat, not raised above the broad and flat- 

 tened muzzle ; nostrils not projecting, directed forwards and slightly 

 downwards. Ears shorter than the head, triangular, with rather 

 broadly rounded tips ; outer margin straight, terminating towards the 

 angle of the mouth in a small lobe separated by a shallow notch ; 

 tragus short, slightly narrowed upwards and rounded off above, 

 reaching its greatest width opposite the base of the inner margin ; 

 at the base of the outer margin a small triangular lobule. 



Under surface of the base of the thumbs and soles of the feet with 

 broad fleshy pads. In some specimens the pad extends along the 

 inferior surface of the thumb almost to the base of the claw, which 

 is very small and acutely pointed, as in V. noctula. On the foot the 

 fleshy sole forms almost a circular disk, especially towards the toes, 

 under which its round margin projects slightly. The toes are short, 

 not exceeding half the foot in length, and are armed with short 

 claws. 



Wings rather short ; wing-membranes from the base of the toes. 

 Tail projecting by the extreme tip only ; calcaneum short and feeble. 



Fur fine and very dense, moderately long, scarcely extending upon 

 the membranes ; above generally bright reddish brown, paler be- 

 neath. 



Upper incisors short, the second and shorter outer cusp of the 

 inner incisor exceeding very slightly in vertical extent the unicus- 

 pidate outer incisor ; lower incisors trifid, not crowded. 



Length, head and body l"-75, tail l"-3, ear 0"-48, tragus 0"-2, 

 forearm 1"-1, thumb 0"-22, third finger 2", fifth finger l"-4, tibia 

 0"-45, foot 0"-25.

 rim Province; Andaman Islands ; Sumatra, Java, Philippine Islands. 



In this species, as in V. tylopus also, the fleshy footpads without 

 doubt enable the animal to cling to the under surfaces of large leaves 

 and fruits — perhaps not so effectively, however, as the much more 

 highly specialized pedunculated sucking-disks of Thyroptera tricolor 

 from the American continent enable that animal to adhere to smooth 

 surfaces as securely as a fly.
