Geographic distribution. — Warmer parts of America north to the 

 Bahama Islands and central Mexico. 



Characters. — Humerus with trochiter nearly as large as trochin 

 and projecting noticeably farther beyond head, its surface of articu- 

 lation with scapula nearly half as large as glenoid fossa and very 

 definitely outlined, epitrochlea well developed, but short and thick, 

 with broad spinous process, capitellum distinctly out of line with 

 shaft; second manal digit with fully developed metacarpal but no 

 phalanges; third finger with two phalanges; shoulder girdle normal 

 in structure, but presternum relatively large and strong, its width 

 equal to length of presternum and mesosternum together, its keel 

 slanting backward ; mesosternum very narrow, its keel much higher 

 than its width posteriorly; xiphisternum scarcely longer than broad, 

 its keel low but distinct; foot normal; fibula thread-like, usualty 

 cartilaginous at its upper extremity, which extends to head of tibia; 

 pelvis essentially normal, but ilia unusually expanded laterally and 

 dorsal and ventral profiles of ossa innominata more nearly parallel 

 than in any other bats except the Rhinolophidae and Hipposideridae, 

 sacrum with boundaries of vertebrae nearly or quite effaced, though 

 general form of bone not peculiar; vertebra? from last dorsal to 

 antepenultimate lumbar fused into a solid, laterally compressed mass 

 from which all boundaries of the original elements are obliterated, 

 last two lumbar vertebras free; skull without postorbital processes; 

 premaxillaries complete, the slender palatal branches fused in me- 

 dian line, leaving two small, lateral foramina and a slight anterior
