Geographic distribution. — Warmer parts of America, north to the 
Bahamas and southern California. 
Characters. — Teeth essentially normal, though in some genera there 
occurs a reduced condition of the mesostyle and commissures of m 1 
and m 2 , and of the paraconid and metaconid of m x and m 2 ; humerus 
with definite secondary articulation with scapula, epitrochlea large, 
with slightly developed spinous process; muzzle with noseleaf ; lower 
lip without plate-like outgrowths. 
Principal subdivisions. — This subfamily, containing all the leaf- 
nosed American bats with normal teeth, has fourteen well defined 
genera. 
KEY TO THE GENERA OF PHYLLOSTOMINCE. 
Lower incisors 1-1. 
Lower premolars 3-3 Tonatia, p. 128. 
Lower premolars 2-2. 
Audital bullae very large, their height on inner side greater than 
width of basioccipital A nthorliina, p. 129. 
Audital bullae not enlarged. 
Crown of outer upper incisor as wide as that of inner ; audital 
bullae well developed Mimon, p. 129. 
Crown of outer upper incisor much narrower than that of in- 
ner, audital bullae very narrow Ghrotopterus, p. 133. 
Lower incisors 2-2. 
Lower premolars 2-2 Phyllostomus, p. 130. 
Lower premolars 3-3. 
Rostrum as long as braincase ; molars wider than palate ; the 
W-pattern much distorted W ampyrus, p. 134. 
Rostrum shorter than braincase ; molars narrower than palate ; 
W-pattern essentially normal. 
Middle lower premolar about as large as third. 
Audital bullae large, their greatest diameter much more 
than distance between them Otopterus, p. 126. 
Audital bullae small, their greatest diameter scarcely equal 
to distance between them. 
Inner upper incisor chisel-shaped, the front face of 
the two teeth together scarcely convex ; second up- 
per premolar without distinct style and with main 
cusp in front of middle of crown, its apex curved 
backward Gly phony cteris, p. 125.
