Show 556 MR. G. E. DOBSON O N T H E GENUS TAPHOZOUS. [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 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. saccolcemus is always some shade of brown. Structurally it is distinguished by the complete absence of a gular sac in the females; for in T. saccolcemus a sac exists iu 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, 1st ph. 1"*2, 2nd ph. 1"*2; fourth finger 2"*5 ; tibia 1"*0 ; foot and claws 0"*6. Hab, Labuan. Type in the collection of the British Museum. 10. TAPHOZOUS PELI. Taphozous peli, Temminck, Esq. Zool. sur la cote de Guinee, 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 T. saccolcemus. Lower lip with a deep narrow groove. Gular sac very large in males, rudimentary (the margins only defined) in females. No radio-metacarpal pouch. Fur of the body short, not extending to the membranes ; distribution similar to that of T. nudiventris. Above, dark reddish-brown, beneath, a slightly paler shade of the same colour. Length: head and body4"*2; tail l"*2; ear 1"*0, tragus 0"*3 ; forearm 3"*5 ; thumb 0"*6 ; second finger-metacarp. 3"*3, 1st ph. 1"*45, 2nd ph. 1"*45; fourth finger-metacarp. 2"*1, 1st ph. 0"8, 2nd ph. 0"*45 ; tibia 1"*3 ; foot and claws 0"*8. Hab. Africa, Gold Coast (Leyden Museum), Cameroon Mountains (Brit. Mus.), East Africa (Cambridge Mus.). Type in the collection of the Leyden Museum. |
