Rhinolophus clivosus, Riippell, Atlas, Reise nord-ost Afrika, p. 47 (1824); Peters, MB. Akad. Beri. 1866, p. 16, 1871, p. 311.

Ears considerably shorter than the head, acutely pointed; inner margin of the car-conch convex throughout, but less convex above, tip not attenuated; antitragus separated by an obtuse notch, short, evenly convex; nose-leaf not concealing the muzzle, divided by a simple notch in front; horizontal plate of the sella with semicircular sides much broader than the vertical process, which is slightly narrower in the middle and similar to that in Rh. ferrum- equimtm, its summit rounded-off above, considerably surpassed in height by the crest of the connecting-process, which forms an acute thickened projection; terminal leaf rather short and acute; horseshoe-shaped nose-leaf not concealing the sides of the muzzle.

Wings from the tibiae slightly above the ankles; last small caudal vertebrae projecting.

Fur sulphur-brown above, beneath canary-colour.

First upper premolar in the tooth-row in immature specimens; in adults closely wedged in between the adjoining teeth.

Length (of an adult ♀), head and body 1"'75, tail 0"-95, head 0"-8, ear 0"-65, nose-leaf 0''-45 x 0"’28, forearm " -75, thumb O''-3; third finger—metacarp. 1"-2, 1st ph. 0"-55, 2nd ph. "; fourth fingermetacarp. l',-3, 1st ph. O',-28, 2nd ph. 0"-65; fifth finger—metacarp. 1"-25, 1st ph. O',-38, 2nd ph. 0”-55; tibia 0"-7, foot 0"-4.

Hab. N.E. Africa (Kordofan).

This species is very closely allied to Rh. landeri and to Rh. ferrum-equinum. It is distinguished from the former by the form of the upper margin of the posterior connecting-process of the sella, by the smaller size of the horseshoe-shaped membrane, and by its larger feet; from the latter by the form of the ears and of the upper margin of the same connecting-process, by the position of the first upper premolar in the tooth-row, and by its conspicuously smaller size.
