HIPPOSIDEEUS. 289 



Distribution. Assam, Sylhet, and throughout Burma, also Siam 

 and Java. 



This species is closely allied to H. speoris, but distinguished by 

 larger size, proportionally larger ears, and by the posterior margin 

 of the interfemoral membrane forming a salient angle, instead of 

 being straight.

Ears extending to the end of the muzzle when laid forward, 

 broad, with very blunt rounded tips, outer margin straight, not 

 concave below the tip. A low raised band of skin connects the 

 base of the ears across the crown of the head ; this band is hairy 

 and requires to be looked for. 



Nose-leaf small, oblong ; no secondary leaflets at the side of the 

 horseshoe, which is of about the same width as the posterior leaf, 

 or rather narrower ; sella less broad transversely than the anterior 

 leaf ; posterior leaf rounded behind, the front surface concave, 

 divided longitudinally into four cells. Frontal sac well developed 

 in males, rudimentary in females. 



Wing-membrane from the ankle or tarsus ; interfemoral mem- 

 brane projecting angularly slightly behind ; tip of tail free. 



Colour varying from golden chestnut to very dark reddish brown, 

 almost black, above, paler, sometimes white, below. The fur is 

 generally pure white, buffy white, or grey for three-quarters of its 

 length, the tips reddish brown, or ashy brown, or blackish. Some 

 specimens are brilliant golden or bright ferruginous. Dobson found 

 that several golden-coloured specimens examined by himself were 

 pregnant females, but males were subsequently obtained by An- 

 derson in Burma exhibiting the same brilliant coloration, though 

 both males and females were found in adjoining caves of the usual 

 coloration, whitish fur with dark tips. 



Dimensions. A male Burmese specimen measured : head and 

 body 1-75 inches, tail 1-15, ear from crown 0-75, forearm 1-55.
