556 MR. G. E. DOBSON ON THE GENUS TAPHOZzOUS. [Nov. 2, 
black, the bases of the hairs white; beneath wholly pure silky white 
as in Vesperugo temminckii. The integument of the back is white ; 
the antebrachial and interfemoral membranes, and that portion of the 
wing-membranes between the forearm and third finger, white, while 
that portion of the wing-membrane between the third and first fin- 
gers 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 correspond- 
ing part above. 
This species is closely allied to 7. saccolemus, 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 7’, sac- 
colemus 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. saccolemus 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. 
Length: head and body 3-4; tail 1’"1; ear 0'°9, tragus 0°25 ; 
forearm 2'°9; thumb 0'°5; second finger—metacarp. 2’-8, Ist ph. 
1-2, 2ad ph. 12; fourth finger 2-5; tibia 1-0; foot and claws 
06. 
Hab. Labuan. Type in the collection of the British Museum. 
10. TapHozous PELI. 
Taphozous peli, Temminck, Esq. Zool. sur la céte de Guinée, p. 82. 
Ears proportionally smaller and more triangular than in the other 
species, upper half of the inner margin of the ear-conch papillate ; 
tragus rather short, evenly rounded above as in 7. saccolemus. Lower 
lip with a deep narrow groove. Gular sac very large in males, rudi- 
mentary (the margins only defined) in females. No radio-metacarpal 
pouch. 
Fur of the body short, not extending to the membranes; distribu- 
tion similar to that of T. nudiventris. 
Above, dark reddish-brown, beneath, a slightly paler shade of the 
same colour. 
Length: head and body 42; tail 1"°2; ear 1"°0, tragus 0'°3; 
forearm 3'"5; thumb 0'°6; second finger—metacarp. 3'°3, Ist ph. 
1:45, 2nd ph. 1°45; fourth finger—metacarp. 2’"1, lst ph. 08, 
2nd ph. 0":45; tibia 1’°3; foot and claws 0'8.
