the muzzle external to the horseshoe, and by the simple form of the 

 horseshoe, which is generally longer than broad, and has a very 

 distinct ridge passing backwards from the centre of its front surface 

 between the nasal apertures ; the ears are also well developed, and 

 the inner margin of the ear-conch more evenly convex throughout 

 from the base to the tip.

 p. 326; Dobson, Monogr. Asiat. Chiropt. p. 73 (1876). 



Ears as long as the head, much longer than broad ; inner margin 

 of the ear-conch almost evenly convex from the base to the tip, 

 which is short and subacutely pointed and inclined slightly out- 

 wards owing to the concavity which occupies the upper fourth of 

 the outer margin, and commences rather abruptly beneath the tip ; 

 lower three fourths of the outer margin convex, at the commence- 

 ment of the lower third a small weU-defined projection, not so long 

 or acutely pointed as in Ph. speoris. Nose-leaf well developed, the 

 erect leaf large, wider than the sella, with a regularly convex upper 

 margin and a concave front surface undivided by vertical ridges ; 

 horseshoe slightly wider than long, with an unnotched free front 

 margin ; no secondary leaflets external to the horseshoe ; in males 

 a well-developed frontal sac, which is quite rudimentary in females. 



Wings from the metatarsi ; calcaneum nearly as long as the foot ; 

 tail projecting abruptly (as in Ph. speoris) for more than one tenth 

 of an inch beyond the free margin of the interfemoral membrane, 

 which is straight behind between the extended calcanea. 



Fur dark brown above, the base of the hairs very pale brown, 

 almost white, then dark brown succeeded by light brown, the ex- 

 tremities dark brown ; beneath, paler brown throughout ; integu- 

 ment and ears dark brown.

Ears slightly shorter than the head ; inner and outer margins of 

 the ear-conch equally convex in their upper thirds, so that the ear 

 is evenly rounded off above without a distinct tip. Transverse erect
