12. EiHINOLOPHUS THOMASI, Sp. 11. (Plate III. fig. 10.) 



Bhinolophus affi,nis rouxi ? (non Temm.), Tliomas, Ann. Mus. 

 Civ. Genova (2) x. (1892) p. 15, pi. xi. fig. 3. 



Diagnosis. Allied to Rh. rouxi, but p" external to the tooth-row. 

 Smaller than rouxi, with considerably shorter metacarpals, and 

 the tip of the lancet excessively shortened. Third metacarpal 

 30-4-31 mm. Forearm 44-8-45-7 mm. 



Details. While being similar to Rh. rouxi in the shape of the 

 sella and the ears, and the proportionate length of the tail, 

 Rh. thomasi differs, externally, from that species in the following 

 particulars : — 



The horse-shoe is considerably narrower ; it is even narrower 

 than in the smaller borneensis and in the much smaller malayanus. 

 The tip of the lancet is exceedingly short, almost rudimentary ; it 

 is the hastate lancet of rou,xi carried to an extreme. 



The general size is smaller, as seen by the measurements of the 

 forearm. But the metacarpals are proportionately mifjch shorter, 

 as short as in the much smaller malayanus. III." is comparatively 



Measttrements of Rhinolophus rouxi and thomasi.
