9. Taphozons affinis. 



Taphozous affinis, Dobson, Ann. Sj- May. Nat. Hist. 1875, xvi. p. 232 ; 

 P. Z. S. 1875, p. 655} Moimjr. Asiat. Ckiroj}t. p. 173 (187G). 



Ears shorter than the head ; inner margin of the ear-conch not 

 papillate ; tragus rather short, almost quite circular above, outer 

 surface concave. Lower lip with a deej) narrow groove in the 

 centre of its upper surface and in front (Plate XX. fig. 5). Male 

 with a large gular sac, as large as in 2'. saecolcemus, rudimentary in 

 the female, the margins of the sac alone developed. No radio- 

 metacarpal pouch. 



Wings from the ankles. 



Distribution of the fur as in T. saccolcemus. Above black, the 

 bases of the hairs white ; beneath wholly pure silky white. The 

 integument of the back is white ; the antebrachial and interfemoral 

 membranes, and that portion of the wing-membrane between the 

 forearm and third finger, white, while that portion of the wing- 

 membrane between the third and first fingers is black mottled with 

 white along the third finger ; beneath, the wing-membrane is pure 

 white from the sides of the body outwards as far as the third finger, 

 beyond which it is coloured as the corresponding part above. 



This species is closely allied to T. saccolcemus, resembling it in its 

 general structure and in measurements. It is at once distinguished 

 by the pure whiteness of the fur of the thorax and abdomen and of 

 the wing-membrane (the same in the four specimens preserved in 

 spirit, from which the original description was made), which in T. sac- 

 colcemus is always some shade of brown. Structurally it is distin- 

 guished by the complete absence of a gular sac in the females ; for 

 in T. saccolcemics a sac exists in the females also, though much less 

 developed than in the males. The margins of a gular sac are well 

 defined in this species ; but no cavity exists.
