Show 1 900.] MAMMALS OF SIAM AND THE MALAY PENINSULA. 349 generally rest suspended by their hind feet, with the head rather thrust up, and the big ears flat against their necks. In April 1898 I found these bats fairly numerous on the little island of Pulo Tikus, near Penang. They were living in the small caves by the sea, which are only accessible (to human beings) at low tide ; the way the bats crawl over the rocks is wonderful, the general effect being more that of a crab than a mammal. I have also received a specimen of this species from Chantaboon. Colour. Five specimens (3 d , 2 2) caught on Pulo Tikus on the same day (9.4.98J showed great variations in colour:- o" (a). Pale mouse-colour, tinged with rufous, breast lighter, belly white, black patch on throat. d (b). Very yellowish rufous. o* (c). Dark grey; this specimen was rather smaller than either a or b, which were subequal in size. 2 (d). Pale mouse-colour, breast lighter, belly wiiite. 2 (e). Similar to d, but darker and browner above. The illustration of the head of this species given by Dobson (P. Z. S. 1875, and Mon. As. Chir. p. 167), which has been used in subsequent books (Cassell's Nat. Hist. i. p. 316, and Blanf. Faun. Ind., M a m m . p. 347, fig. 114), is, I venture to think, not adequate in giving a good idea of the physiognomy of this bat. The appended sketches (see p. 348) of a male, from Bangkok, drawn from life, will be seen to differ from Dobson's figure in the profile of the nose, the form and serrations of the ear, and the bristles on the face. Also T. melanopogon has a bright, intelligent look, which is lost in Dobson's figure, apparently drawn from a spirit specimen. Distribution. India, Burma, Siam, Cochinchina, Malay Peninsula (Lancavy, Penang), Java, Borneo, Philippines. 95. TAPHOZOUS LONGIMANUS Hardw. Long-armed Sheath-tailed Bat. Taphozous longimanus, Blanf. Faun. Ind., M a m m . p. 348. Dr. F. A. Jentink (Notes from the Leyden Museum, vol. xix. p. 54, January 1897) says of specimens of this bat from Sintang, Borneo :-" The wings are white, strikingly contrasting with the dark-coloured (in alcohol) rest of the animal." Mr. Oldfield Thomas (A. M . N . H . ser. 7, vol. ii. p. 246, Sept. 1898) describes these white-winged specimens as Taphozous longimanus albipinnis, with a female from Labuan, collected by the late M r . A. H . Everett, as the type of the subspecies, and says : " Four other Bornean specimens are similarly white-winged, and there is also a white-winged specimen in the Museum collection from Malacca collected long ago by Mr. A. Charlton " (vide Dobson, Cat. Chir. B. M . p. 385). During a few days I spent in Labuan in Sept. and Oct. 1897 a white-winged Taphozous was very noticeable, flying at evening-time in large numbers over the road from Usher Market to the Post Office, but I do not knowr whether they belonged to this species |
