KNUD ANDERSEN 



(174) 



horse-shoe. Sella of the megaphyllus type: decidedly broader at 

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

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

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

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

 lens a mat of exceedingly short white hairs is observable). 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 whole 

 of the posterior leaf densely haired. — Three mental grooves, as 

 in all primitive species of Rhinolophus. 



Ears of the megaphyllus pattern: rather long and broad, 

 reaching a little beyond the tip of the muzzle when pressed for- 

 wards; width of ears very 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 primitive 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 y the length of the first 

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

 than first phalanx. 



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

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

 owing to the shortness of the tail, somewhat concave. Tip of tail 

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

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

 individual variation. 



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

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

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

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

 average. 



Dentition ('): — p. is siluated in 1ho tooth-row, but a little 

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

 higher than the cingulum of p r p., and p, well separated, p- 

 completely in row, with a distinct cusp, pointing inwards; height
