1 84 Catalogue of Mammalia inhabiting [No. 171. 



nasal disk covers the short, rounded, hairy muzzle, which has two leaves 

 on either side; the transversal membrane is concave, as broad and long as 

 the horizontal horse- shoe, which it joins under a right angle, while its 

 sides are almost in contact with the ears. The latter are sub-erect, broader 

 than long, their breadth equalling the length of the head ; the shape is 

 broad, pyriform, narrowing towards the apex, which appears like a small 

 artificially rounded flap, scarcely elevated above the level of the fur co- 

 vering the vertex. More than two- thirds of the back of the ear is 

 covered with fur, leaving a narrow naked line along the external mar- 

 gin, which, as well as the singular shape of the ear itself, affords a dis- 

 tinguishing character. The hairs are buff or whitish at the base, the 

 other half of their length brown. The general colour of the upper parts 

 is deep-brown, with a slight reddish hue, becoming a shade lighter be- 

 neath. 



This species somewhat resembles Hipposideros apiculatus, Gray fVes- 

 pertilio speoris, Schneider, apud Schreber ; Rhinolophus speoris, Geof- 

 froy,) from which it however differs in the absence of the frontal pore, 

 in the shape of the ears, and in colours. A solitary male was captured 

 in the valley of Pinang.

 This bat having the characteristic distinction of the upper incisor, 

 described by Horsfield, is above greyish-brown, beneath light- greyish, 

 measuring in length three and two- eighth inches, of which the tail is 

 one and four- eighth inch. Extent of flying membrane ten and 

 four- eighth inches. It differs from V. adversus in having on each side 

 five molars, of which but two are spurious, which character also obtains 

 in V. cineraceus, Blyth MSS. and specimen in the Museum Asiatic 

 Society, which (as observed by Mr. Blyth,) as well as the present, may 

 prove varieties of V. adversus, Horsfield.
