CHIROrXERA 



and I\. Jiipposidenis ; antitragal lobe about lialf as High as conch, 

 its width about equal to its height. Wing pecuUar in the 

 shortening of the tirst jshalanx of fourth finger to a little more 

 than one-third that of second (average of 1 specimens from Gard, 

 Fi'ance : tirst phalanx, 6'G mm.; second phalanx, 17 '4 mm.; 

 ratio of first to second, 38 -f )• -Foot averaging slightly more 

 than half as long as tibia. 



Colour. — While essentially as in Illiinoloijlins ferrmii-eqmnuni 

 and M. hipposideros, the colour usually differs slightly in the more 

 evident contrast of the light area between ears and the more 

 drabby general effect of underparts. Median region below 

 occasionally rather paler than usual, sometimes nearly as in 

 R. mehehj). 



Skull. — In both size (greatest length about 19 mm.) and form 

 the skull is somewhat intermediate between that of mdywlophun 

 ferrum-equinum and B. hipposideros. It resembles or surpasses 

 the latter in the breadth of brain-case relatively to naTro^\" 

 maxillar}' region, but more nearly agrees with the former in the 

 nearly parallel-sided mesopterygoid space, the anterior boi'der of 

 which is separated from posterior molars by well defined palatal 

 eraarginations. The mesopterygoid .space is, however, shorter in 

 proportion to its width than in B. ferrum-equinum. Floor of 

 brain-case between cochlese less narrowed than in the preceding 

 species. Nasal region slightly less inflated than in R. hipposideros, 

 and inflated area relatively shorter, its posterior border rising 

 abruptly above interorbital level. 



Tectli. — In all respects the teeth closely resemble those of 

 Blii iiolophu8 ferrum-equinum (apart from their smaller size), excejjt 

 that the upper canine is relatively less robust, the anterior upper 

 premolar is less reduced (its crown area about double that of 

 uj:)per incisor), and anterior lower premolar is less crowded 

 between canine and posterior premolar. 



Measurements. — For cranial and external measurements see 

 Tables, pp. 156 and 160.

JteiiiarJcs. — Mhinolopihus euryale is so readily distinguishable 

 from all the other European membsrs of the genus, except 

 R. mehehji, as to renuire no special comparisons. From R. meheli/i 

 it is most easilv distinguished bv tlie form of the lancet and
