Hipposideros lylei, sp. n. 



A large species related to H. pratti, Tlios. 



Size rather less than in H. pratti. General characters of 

 the H. armiger group, including the long feet, development 

 of a posterior transverse crest behind the normal nose-leaf, 

 and the uninflated forehead of the skull. Nose-leaf similar 

 on the whole to that of H. pratti, but the supplementary- 

 transverse posterior crust higher, attaining 5 mm. at its 

 highest point on each side of its median cleft, and less 

 heavily haired, but the increase in height may perhaps be due 

 to sex ; normal transverse crest similarly high in the centre, 

 sloping down laterally, its front surface divided by a promi- 

 nent median and two indistinct lateral ridges ; anterior 

 horseshoe much more deeply notched in front, the median 

 notch nearly 2 mm. in depth, the horseshoe on each side of 

 it forming two forwardly projecting lappets, outside which 

 again there are two shallower notches, unknown elsewhere in 

 the genus. Ears rather narrower than in pratti. Tibise and 

 feet very long and slender. 



General colour dull buffy or clay-colour, washed with 

 brown. 



Skull similar in its general characters to that of II. pratti 

 as opposed to those of //. diadema and armiger ; but it is 

 smaller throughout, the sagittal crest (though of a male as 

 compared witli a female) less developed and less abruptly rising 

 above the forehead ; area of forehead smaller and not quite 

 so flat, the median part above the anterior nares slightly 

 elevated, while its postero-lateral portion is somewhat concave 

 internal to the w T ell-marked supraorbital edges. Posterior 

 palate more deeply excavated mesially. Teeth similar in 

 general characters, but smaller throughout. 



Dimensions of the type : — 



Forearm 78 mm. 



Ear 27 x 21 j third finger, metacarpal 54, first phalanx 25 ; 

 lower leg and hind foot (c. u.) 51. 



Skull : greatest length to front of canine 29 ; basi-sinual 

 length 18-7; zygomatic breadth 16 ; interorbital breadth 9'6 ; 

 mastoid breadth 14; front of canine to back of m 3 11'2; 

 three upper molars together 6'4 ; three lower molars 10*6.
