Show 1875.] MR. G. E. DOBSON ON THE GENUS TAPHOZOUS. 555 II. No radio-metacarpal pouch; lower lip divided in the centre of its upper surface, and in front by a deep narrow groove. Subgenus 2. TAPHONYCTERIS. 8. TAPHOZOUS SACCOLCEMUS. Taphozous saccolaimus, Temminck, Monogr. Mammal, ii. p. 285. pl. 60. Taphozous crassus, Blyth, Journ. As. Soc. Beng. xiii. p. 491. Taphozous pulcher, Elliot, I.e. p. 492. Ears shorter than the head; tragus concave on outer surface, upper margin regularly convex, margined posteriorly by a fringe of fine hairs ; inner margin of the ear-conch smooth, not papillate; gular sac well developed in both male and female, but much larger in the male; lower lip with a deep narrow groove in the centre of its upper surface and in front. No radio-metacarpal pouch. Wings from the ankles. On the upper surface the fur of the body scarcely extends upon the wing-membrane, the line of attachment of which seems to limit its extent; posteriorly the fur terminates, as on the sides, in a well-defined line limited by the root of the tail; the interfemoral membrane and the legs are quite naked, the feet are also naked, thus differing from the greater number of, if not from all, the species of the genus. Beneath, the chin and sides of the gular sac are covered with very short hair, the thorax and abdomen with moderately long fur, as on the upper surface; the antebrachial membrane has a few fine hairs; and the wing-membrane is covered as far as a line joining the middle of the humerus and the femur, a line of fur passing outwards to the carpus and occupying a considerable triangular patch of membrane there between the forearm and fifth metacarpal bone. Fur, above, white at the base, the greater part of the hairs dark-brown, the surface mottled with small irregular white patches; beneath, reddish brown. Length : head and body 3"*5 ; tail 1"*3; ear 0"*8, tragus 0"*23; thumb 0"*5; second finger-metacarp. 2"*75, 1st ph. 1"* 15, 2nd ph. l"-2; fourth finger 2"*65 ; tibia l"*2 ; foot and claws 0"*65. Hab. Lower Bengal (Sylhet) ; Burma ; Malay peninsula ; Sumatra; Java. Type in the collection of the Leyden Museum. 9. TAPHOZOUS AFFINIS. Taphozous affinis, Dobson, Ann. Mag. Nat. Hist. 1875, xvi. p. 232. 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 deep narrow groove in the centre of its upper surface. Male with a large gular sac, as large as in T. saccolcemus, rudimentary in the female, the margins of the sac alone developed. No radio-metacarpal pouch. Wings from the ankles; fur, above, |
