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 , and m „ ; 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 PHYLLOSTOMIN^E. 



Lower incisors 1-1. 



Lower premolars 3-3 Tonatia, p. 128. 



Lower premolars 2-2. 



Audital bull® very large, their height on inner side greater than 



width of basioccipital Anthorhina, p. 129. 



Audital bulla? not enlarged. 



Crown of outer upper incisor as wide as that of inner ; audital 



bulla? well developed Mimon, p. 129. 



Crown of outer upper incisor much narrower than that of in- 

 ner, audital bullse very narrow Chrotoptcrus, 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 Yampyrus. p. 134. 



Rostrum shorter than braincase; molars narrower than palate; 

 W-pattern essentially normal. 

 Middle lower premolar about as large as third. 



Audital bulla? large, their greatest diameter much more 



than distance between them Otopterus. p. 126. 



Audital bulla? 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 Glyphonycteris, p. 125.
