being completely coated. Prepared specimens show the 

 stippled margin noted in typical examples of the variety. 

 All the specimens are broadly oval, narrowed at anterior 

 extremity. Length varying from 6 to 8'50 mm., and breadth 

 from 5 to 7 mm. 



LI. — Five new Rhinolophi from Africa. 

 By Knud Andeesen. 



In working out a revision of the Ethiopian species of the 

 genus RMnolophus I find the following new forms in the 

 collection of the British Museum to need description : — 



RMnolophus empusa, sp. n. 



Short diagnosis. — Anterior upper and middle lower pre- 

 molars placed in the tooth-row. Sella wedge-shaped (deltoid). 

 Horseshoe as broad as muzzle. A conspicuous dark patch 

 under each eye. Forearm 48 mm. 



Nose-leaves. — Horseshoe covering the muzzle laterally ; 

 a small tooth-like projection on each side of median notch ; 

 underlying leaf easily visible all round. Sella wedge-shaped ; 

 breadth at base about three fourths of vertical height ; lateral 

 margins plainly converging (with a scarcely perceptible 

 constriction in the middle) towards the summit, which is 

 subacutely pointed. Posterior connecting - process long, 

 pointed, slightly curved forwards, as an erect horn, about 

 five sixths the vertical height of the sella, thus projecting 

 far beyond the summit of the sella. Lateral margins of 

 lancet concave in the middle, tip behind constriction about 

 2'3 mm. 



Ears. — Rather short, scarcely reaching tip of muzzle, when 

 pressed forwards along the sides of the head. Tip obtusely 

 pointed. Outer margin concave below the tip. Notch on 

 outer margin shallow, almost rectangular. Extreme breadth 

 of ear somewhat greater than the distance from the notch to 

 the tip. 



Wings. — 5th metacarpal longer than 4th. 1st joint of 

 4th finger equal to three fifths the length of 1st joint of 3rd 

 finger. On the folded wing the tip of the 1st joint of the 

 5th finger reaches as far back as the posterior point of the 

 elbow ; tip of 1st joint of the 3rd finger falling only a trifle 

 short of the same point. Plagiopatagium inserted at base of 

 metatarsus. 



Tail. — Much longer than tibia, about the same length as 

 the combined 1st and 2nd joints of the 4th finger. Tip of 

 tail projecting 2 mm. beyond the membrane (a character
