Geographic distribution. — Bahama Islands and Greater Antilles. 
Characters. — Teeth highly abnormal. Upper molars with low, in- 
distinct paracone and metacone at extreme outer edge of crown. Pro- 
tocone low or obsolete, situated at extreme inner margin. Interme- 
diate region occupied by a wide, shallow groove, angled at middle. 
Lower molars very long and narrow, their cusps too indistinct to be 
positively identified ; m 15 and usually m 2 and m 3 also, with distinct 
median longitudinal groove, their structure almost exactly similar to 
that in the Kiodotinse. Noseleaf small or rudimentary. Rostrum 
and tongue elongated, the tongue armed with lengthened, bristle-like 
papillae. 
History. — Since the genus Phyllonycteris was discovered this group 
has not been distinguished from the Glossopliaginae except by Har- 
rison Allen. He associated it with Brachyphylla to form a section, 
Brachyphyllina or “ Glossopliagina aberrantia,” of the Glossopha- 
ginae. That it should be separated from the Glossophagine bats there 
can be no doubt, but of its near relationship to Brachyphylla I can 
detect no indication. The Phyllonycterinae may be an offshoot from 
some Hemidermine stock, as the teeth in one genus show such a 
resemblance to those of Rhinophylla that it may perhaps indicate 
more than a fortuitous likeness. 
Principal subdivisions. — Three genera are represented among the 
species of Phyllonycterinae thus far known. 
KEY TO THE GENERA PHYLLONYCTERINAE. 
Base of brain case between pterygoids with deep, conspicuous, longitudinal 
groove Reitl irony cteris, p. 174. 
Base of brain case between pterygoids flat with slightly developed median 
longitudinal ridge. 
Second and third lower molars without cusps ; calcar absent ; inter- 
femoral membrane extending to middle of tibia only.
