family, to which latter it is often referred. The typical _N.
leporinus_ is a bat of curious aspect, with strangely folded lips,
erect skin-processes on the chin, and enormous feet and claws. The two
middle incisors are close together, and so large as to conceal the
small outer ones, while in the lower jaw there are but two small
incisors; the premolars numbering 1/2. These bats live near the coast,
and feed on small crabs and fishes.

Most of the remaining members of the family are included in the
subfamily _Phyllostomatinae_, characterized by the presence of a
distinct nose-leaf and the warty chin. The clitoris is imperforate,
whereas it is perforated in the _Mormopsinae_. The incisors are
generally 2/2 (occasionally 2/1), and the molars well developed. The
subfamily is divided into a number of groups or sections. The first of
them, the _Vampyreae_, is characterized as follows: Muzzle long and
narrow in front, the distance between the eyes generally less than
(rarely equal to) that from the eye to the extremity of the muzzle;
nose-leaf horseshoe-shaped in front, lanceolate behind; interfemoral
membrane well developed; tail generally distinct, rarely absent; inner
margin of the lips not fringed; _i._ 2/2 or 2/1, _p._ 2/2 or 2/3;
molars with W-shaped cusps, usually well developed.

Nearly all the _Vampyreae_ appear to be insectivorous, so that the
term cannot be considered indicative of habits; but a few, if not all,
probably supplement their insect diet with fruit. _Vampyrus spectrum_
(the largest bat in the New World) is said to be wholly frugivorous,
and _Otopterus waterhousei_ appears to prey occasionally on smaller
bats. The genera may be arranged in two subgroups according as the
tail is produced to the margin of the interfemoral membrane or
perforates it to appear on its upper surface. In the first division
are included three genera, _Lonchorhina_, _Otopterus_ (or _Macrotus_)
and _Dolichophyllum_ (or _Macrophyllum_), the first represented by _L.
aurita_, characterized by an extraordinary long nose-leaf, and
peculiarly large ears and tragus. In the second subsection are
included _Vampyrus_, _Chrotopterus_, _Tonatia_ (_Lophostoma_)
_Micronycteris_, _Glyphonycteris_, _Trachyops_, _Phylloderma_,
_Phyllostoma_, _Anthorhina_ (_Tylostoma_), _Mimon_, _Hemiderma_
(_Carollia_) and _Rhinophylla_; all, with the exception of the last,
distinguished c
