1900.] MAMMALS OF SIAM AND THE MALAY PENINSULA. 349 



generally rest suspended by then* 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 6* , 2 $ ) caught on Pulo Tikus on the 

 same day (9.4.98 ) showed great variations in colour : — 



3 (a). Pale mouse-colour, tinged with rufous, breast lighter, 

 belly white, black patch on throat. 



c? (b). Very yellowish rufous. 



S (c). Dark grey ; this specimen was rather smaller than either 

 a or b, which were subequal in size. 



$ (cZ). Pale mouse-colour, breast lighter, belly white. 



$ (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., Mamm. 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., Mamm. p. 348. 



Dr. P. 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 Mr. A. H. Everett, 

 as the type of the subspecies, and says : " Pour other Bornean speci- 

 mens 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 know whether they belonged to this species
