CHIROPTEEA 



and B. hipposideros ; antitragal lobe about balf as bigb as conch, 

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

 shortening of the first phalanx of fourth finger to a little more 

 than one-third that of second (average of 10 specimens from Gard, 

 France: first phalanx, 6 - 6 mm.; second phalanx, 17 '4 mm.; 

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

 than half as long as tibia. 



Colour. — While essentially as in BMnolophus ferrum-equinum 

 and B. 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 

 B. mehelyi. 



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

 the skull is somewhat intermediate between that of BMnolophus 

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

 the latter in the breadth of brain-case relatively to narrow 

 maxillary region, but more nearly agrees with the former in the, 

 nearly parallel-sided mesopterygoid space, the anterior border of 

 which is separated from posterior molars by well defined palatal 

 emarginations. The mesopterygoid space is, however, shorter in 

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

 brain-case between cochleee less narrowed than in the preceding 

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

 and inflated area relatively shorter, its posterior border rising 

 abruptly above interorbital level. 



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

 BMnolophus ferrum-equinum (apart from their smaller size), except 

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

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

 upper 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.

Bemarks. — BMnolophus euryale is so readily distinguishable 

 from all the other European members of the genus, except 

 B. mehelyi, as to require no special comparisons. From B. mehelyi 

 it is most easily distinguished by the form of the lancet and
