RHINOLOPHUS 



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. ferrum- 

 equinum. Large upper premolar 

 and upper molars essentially as in 

 _B. ferrnm-eqninum except that in 

 )iv^ there is a distinct meta- 

 style and fourth commissure, 

 and area of tooth is nearly 

 equal to that of m"^. Lower 

 molars as in Rhmolophus 

 ferriim-eqwinnm, except that 

 in m^, almost exactly resem- 

 bles the other teeth, the second 

 triangle having undergone 

 practically no reduction. 



Measurements. — Head and 

 body about 40 mm., tail about 

 30 mm., forearm, 34-5 to 

 41 • 7 mm.jCondylobasal length 

 of skull, 13 "8 to 15 mm. 

 (greatest length 14 • 5 to 16 • 2). 

 Details under subspecies. 



BemarJcs. — Three imperfectly differentiated forms of Bhiiw- 

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

 smaller Mediterranean race, and an intermediate form pecviliar 

 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.*
