KNl'D A\DERSE\ 



horse-shoe. SeUa of the mcgajjJiyllus type: decidedly broader at 

 base tlian at summit, and distinctly constricted at middle; height 

 of sella, from angle between yertical portion and nasal lobe, about 

 4.8 mm.; width at base 2.8, at summit 2.2 mm.; summit broadly 

 rounded otf; front face of sella practically naked (by means of a 

 lens a coat of exceedingly short w^hite hairs is obseryable). Posterior 

 connecting-process low^ and rounded, inserted a little below the 

 summit of the sella. Lancet almost cuneate, the lateral margins 

 being but slightly emarginate. Connecting-process and the wdiole 

 of tlie posterior leaf densely haired. — Three mental grooyes, as 

 in all primitiye species of Rhinolophus. 



Ears of the meg aphy Hits pattern: rather long and broad, 

 I'eaching a little beyond the tip of the muzzle when pressed for- 

 wards; width of ears yery nearly equal to the distance from the 

 notch on the outer margin to the tip. 



Wing-structure (compare the wing-indices below, p. 195) as 

 in all primitiye members of the Rh. simplex group : fourth 

 metacarpal a trifle longer than fifth, third slightly the shortest; 

 second phalanx of third digit less than 1 \ the length of the first 

 phalanx; second phalanx of fourth and fifth digits a little longer 

 than first phalanx. 



Wing-membranes inserted yery nearly on the tarsus. Tail a 

 little longer than . the lower leg. Posterior margin of uropatagium, 

 owning to the shortness of the tail, somewhat concaye. Tip of tail 

 projecting about 1 mm. , a character which , judging from other 

 species of the genus, no doubt is subject to a certain amount of 

 indiyidual yariation. 



Skull essentially as in Rh. megaphyllus, but rather larger, 

 more heayily-built and especially with broader brain-case (see the 

 measurements below of mastoid width and width of brain-case). 

 The teeth will probably proye to be a little larger, at least on 

 ayerage. 



Dentition (^): — pg is situated in the tooth-row% but a little 

 towards the external side; the tooth is blunt, without cusp, scarcely 

 higher than the cingulum of p^^. p^ and p^ well separated, p'^ 

 completely in row, with a distinct cusp, pointing inw^ards; height
