summit of the sella. Lateral margins of lancet slightly emarginate. 

 Connecting-process and posterior leaf densely covered with rather 

 long hairs. — The usual two mental warts, hut no distinct 

 mental grooves. 



Ears reaching somewhat beyond the tip of the muzzle when 

 pressed forwards; greatest width a little larger than distance 

 from notch on outer margin to tip; outer margin , below the tip, 

 deeply concave; lip rather blunt. 



Wing-structure on a very high level of development. When 

 comparing the wing-indices with those of a primitive species of the 

 simplex and lepidus groups (Rli. fallajc may serve as a para- 

 digma of the former, Rh. cognatus of the lattery see wing-indices 

 below, p. 195), the following chief points will be noticed: — 

 First, the third metacarpal is distinctly shortened, and at the same 

 time the fourth and fifth considerably lengthened; second, a very 

 strong shortening of the first phalanx of the fourth digit 

 has taken 'place, this phalanx being only between 1 / 4 and 1 / 5 

 the length of the fourth metacarpal (in all primitive Rhinolophi 

 beween V3 and l U tbe metacarpal); third, all the distal pha- 

 langes are very much lengthened. — This wing-structure is very 

 nearly the same as in Rh. landeri and lobatus. 



Wing-membranes inserted on the tarsus. 



Tail short, about equal to the length of the lower leg; tip of 

 tail scarcely projecting beyond the membrane. Posterior margin 

 of uropatagium, owing to the shortness of the tail, concave. 



Skull of the lander i-lobatus pattern, but very much larger. 



Dentition: — p 3 half in row, a trifle higher than the cingula 

 of the adjacent premolars, p^ and p 4 separated, p- quite in row, 

 the cusp (unworn) represented by an exceedingly small tubercle. 



Affinities. — Rh. alcyone is closely related to Rh. landeri 

 and lobatus, but distinguished, primo visu, by its much larger 

 size. For further remarks see below, under Rh. lobatus.
