Hijjpos icier OS lijlei, up. n. 



A large species related to //. pratti, Thos. 



Size rather less tlian in H. pratti. General characters of the 

 II. armiger group, iiichiding the long feet, development of a jiosterior 

 transverse crest behind the normal nose-leaf, and the uniufiated fore- 

 head of the skull. Nose-leaf similar on the whole to that of II. pratti 

 but the supplementar}' transverse posterior crest 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, slopino- down 

 laterally, its front surface divided by a prominent median and two 

 indistinct lateral ridges ; anterior horseslioe much more deeply notched 

 in front, the median notch nearl}' 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. Tibij© and feet very 

 long and slen^ler. 



General colour dull buffy or clay-colour, washed with brown. 



Skull similar in its general characters to that of //. p-atti 

 as opposed to those of II. diadema and armiijer ; but it is smaller 

 throughout, the sagittal crest ( though of a male as compared with a 

 female ) less developed and less abrupt Ij^ rising above the the forehead ; 

 area of forehead smaller and not quite so flat, the median part above 

 the anterior nares slightU- elevated, while its postero-lateral portion is 

 somewhat concave internal to the well marked supraorbital edges. 

 Posterior palate more deeply excavated mesially. Teeth similar in 

 general charactei's, but smaller throughout.
