Show 550 MR. G. E. DOUSON ON THE GENUS TAPHOZOUS. [Nov. 2, 0"*8, 2nd ph. 0"*9 ; fourth finger 2"*1 ; tibia 0"*9 ; foot and claws 0"*5. Hab. Bengal (Jashpur), Pinang, Burma, Cochin China, Java. Type in the collection of the Leyden Museum. 2. TAPHOZOUS THEOBALDI. Taphozous theobaldi, Dobson, Proc. Asiat. Soc. Beng. Aug. 1872, p. 152. Gular sac absent in both sexes. Inner margin of the ear papillate ; ears larger than in any of the species of Taphozous. Radio-metacarpal pouch well developed, larger than in T. melanopogon. Wings from the tibiae above the ankles. The fur of the head extends upon the face as far as a line drawn between the inner corners of the eyes, the remainder of the muzzle is nearly naked; ear-conch naked, except where a few hairs clothe the basal portion of its inner surface; posteriorly the ears are naked except at the base and along their outer margins. On the upper surface the wing- and interfemoral membranes are quite naked, the fur being strictly limited to the body; laterally the limit of the fur upon the back is defined by a well-marked line, convex inwards in the lumbar region ; in T. saccoleemus and in T. nudi-ventris the line of fur is convex outwards in the same situation; so that in this species the space occupied by fur in the lumbar region is narrower than in any of the other species, and appears to depend on the position of attachment of the wing-membrane. The tail has but three or four long, very fine hairs. Inferiorly, the chin is naked as far as the anterior prolongation of the external margin of the ears ; the fur of the body extends upon the wing-membrane as far as a line joining the middle of the humerus and femur; from this a band of fine hairs extends outwards to the carpus; the interfemoral membrane is naked ; the backs of the toes are covered with very short hairs. Upper incisors very short and blunt. Length: head and body 3"*35 ; tail 1"*35 ; head 1"*15; ear (anteriorly) 1"*1, tragus 0"*28 ; forearm 3"*0; thumb 0"*45 ; second finger 4"*7 ; fourth finger 2"*5 ; tibia 1"*15 ; calcaneum 0"*9 ; foot and claws 0"*65. Hab. Tenasserim Province. Type in the collection of the Indian Museum, Calcutta. 3. TAPHOZOUS AUSTRALIS. Taphozous australis, Gould, Mammals of Australia; Wagner, Suppl. Schreb. Saugeth. v. p. 690. A distinct but rather small throat-sac in males, in females quite absent, the chin being covered with hairs in the position occupied by the throat-sac in the males. Ears large, as long as the head, inner margin of the ear-conch papillate; no lobule at the base of the tragus. Radio-metacarpal pouch well developed. Wings from the ankles or tarsus. Tail slender. |
