110 BULLETIN 57, UNITED STATES NATIONAL MUSEUM. 



Remarks. — While the Hipposideridaj are closely related to the 

 Rhinolophidse, the more highly modified character of the feet and of 

 the pectoral and pelvic girdles appears to be of sufficient importance 

 to allow the group to stand as a distinct family. 



History. — The history of the family has been sufficiently treated 

 under the family Rhinolophidse. 



Principal subdivisions. — Eight genera of Hipposideridse are now 

 known. 



KEY TO THE GENEBA OF HIPPOSIDEKID^B. 



Zygoma expanded into a wide plate, the height of which is nearly or quite 

 equal to distance from m * to glenoid fossa. 

 Braincase scarcely higher than rostrum ; sagittal crest low, normal, 



Tricenops, p. 115. 

 Braincase much higher than rostrum ; sagittal crest terminating ab- 

 ruptly in front of middle of braincase Bhinonycteris, p. 114. 



Zygoma not specially expanded. 



Rostrum less than half as long as braincase; nasal inflation inconspic- 

 uous Clwotis, p. 114. 



Rostrum at least half as long as braincase; nasal inflation conspicu- 

 ous. 



Outer lower incisor separated from canine by space nearly equal to 

 width of its crown ; upper molars with styles unusually well 



developed Ccelops, p. 113. 



Outer lower incisor in contact with canine ; upper molars with 

 normal styles. 



Sagittal crest chiefly developed in interorbital region ; toes 



with traces of original phalanges Ascllia, p. 112. 



Sagittal crest not chiefly developed in interorbital region; 

 toes without traces of original phalanges. 

 Transverse diameter of cochlea less than twice width of 



basioccipital H ipposideros, p. 110. 



Transverse diameter of cochlea more than three times 

 width of basioccipital Anthops, p. 113.
