 Upper incisor very small, but usually well formed and with distinct 

 rounded crown with slight cusp on inner side. Lower incisors trifid, 

 the outer larger than the inner, the four teeth forming a continuous 

 row between canines. Upper canines heavy, but simple in form, 

 without secondary cusps or conspicuous cingula. Lower canines 

 rather weak. First upper premolar (pm s ) and second lower pre- 

 molar small, f unctionless, usually crowded quite out of the tooth row. 

 - Other teeth showing no special peculiarities ; m * and in m 2 without 

 hypocone, m 3 with five cusps and three commissures, in most species 

 a rudimentary fourth, the crown area of the tooth much more than 

 half that of m 1 or m 2 . Lower molars with the cusps all well devel- 

 oped and normal in position. Skull with distinct sagittal crest, small 

 audital bullae, and large cochlea 1 . Basisphenoid pits absent. Tail 

 present, well developed. 



Species examined. — Probably half of the known species have been 

 examined during the preparation of this paper, including skeletons of 

 Rhinolophus femini-eqii'unnn (Schreber), R. afpnis Horsfield, R. 

 arci/atus Peters, R. capensis Liechtenstein, R. coriuitus Temminck,
