RHINOLOPIIUS 



149 



molars less contrasted in size than in the larger animal, and 

 separated from each other by a slight space in which lies 

 the minute middle premolar, less 

 crowded outward than in B. ferruvi- 

 eqwiniim. Large upper premolai 

 and upper molars essentially as in 

 R. ferrum-eqmnum except that in 

 m^ there is a distinct meta- 

 style and fourth commissure, 

 and area of tooth is nearly 

 equal to that of m"^. Lower 

 molars as in Hhinolophus 

 ferrKrn-t'quinum, except that 

 in M«3, almost exactly resem- 

 bles the other teeth, the second 

 triangle having undergone 

 practically no reduction. 



Measurements. — Head and 

 body about 40 mm., tail about 

 .'jO mm., forearm, 34-5 to 

 4rl • 7 mm.,condylobasal length 

 of skull, 13 "8 to 16 mm. 

 (greatest length 1 4 • 5 to 1 6 • 2). 

 Details under sub.species. 



Bemarks. — Three imperfectly differentiated forms of Bhino- 

 lophus hipposideros occur in Europe : a larger central race, a 

 smaller Mediterranean race, and an intermediate form peculiar 

 to Great Britain and Ireland. Without examination of much 

 more complete material than that now available it is impossible 

 to reach any wholly satisfactory conclusion as to the status and 

 interrelationships of these forms. The characters here given are 

 those published by Andersen in 1905.*
