Five neio Rliinoloplii/yow Africa. 379 



■\vliicli, liowever, no (If)ubt will prove to be subject to a 

 certain amount of individual variation). Hinder border of 

 interfemorjil. between tips of calcars, almost square. 



Colour (of spirit-specimen). — Lij^ht brown above, greyish 

 beneath. Sides of face yellowisli white, with a strongly 

 marked dark brown patch under each eye. Membranes dark 

 brown ; free margin of plagiopatagium very narrowly 

 bordered with whitish. Forearm, metacarpals, and finger- 

 joints yellowish. 



Skull. — Essential characters as in Rh. Blasii, but parietal 

 region of skull still more globular; frontal region con- 

 siderably less constricted. Extreme width of brain-case 

 slightly greater than zygomatic width. jMedian anterior 

 point o£ palatal bridge opposite front of m^ ; median posterior 

 point drawn out into a tooth-like projection. Upper margin 

 of mandible from condyle to base of coronoid process almost 

 straight. Coronoid process very small, projecting only a 

 trifle beyond the highest cusp of in^. 



Dentition. — Small anterior upper premolar (p-) placed in 

 the tootii-row. Upper canine and posterior premolar ( p^) 

 widely separated. Cusp of p^ three fourths the height of 

 the canine. Middle lower premolar {p-^ extremely small, 

 hut placed entirely in the tooth-row, separating p2 and /^^from 

 each other; p.2 one third the height of the canine. Cusp of 

 lower p^ not quite as high as the antero-exterior cusp of mj. 



Type. — ? ad. Zomba, Nyasa, collected by Mr. A. 

 Whvte, Jan. 1893, presented by Sir Harry Johnston. 

 13.M. no. 93. 7. 9. 33. 



Distribution. — Only one specimen, the type, examined. 



liemarks. — This fine species stands quite alone among the 

 African lihinolophi, being the only hitherto known species 

 with a wedge-tormed sella. Its nearest ally is the South 

 European Eh. Blasii. In dentition lih. empusa occupies a 

 slightly more primitive position than Rh. Blasii: in the 

 former the lower ^'3 is still entirely in the tooth-row, in the 

 latter it is just on the point of being driven out on the 

 exterior side of the tooth-row.
