s the forearm. The dentition is _i._ 2/1, _c._ 1/1, _p._ 2/3, _m._
2/2, while the index finger has no claw, and the wings arise from the
spine. _Eonycteris_, with the dentition _i._ 2/2, _c._ 1/1, _p._ 3/3,
_m._ 2/3, is also represented by a single species, _E. spelaea_, from
Tenasserim, Burma, and the Malay Peninsula and Islands, which has
somewhat the appearance of a _Roussettus_, but the absence of a claw
in the index finger and the presence of the characteristic tongue and
teeth at once distinguish it. _Carponycteris_ (_Macroglossus_) and
_Melonycteris_, the former with several and the latter with a single
species, are closely allied Indo-Malay and Papuan genera, the index
finger in both having a claw, but the number of the teeth being the
same as in _Eonycteris_. _C. minimus_ is the smallest known species of
the suborder, much smaller than the serotine bat of Europe, with the
fore-arm scarcely longer than that of the long-eared bat. It is nearly
as common in certain parts of Burma as _Cynopterus marginatus_, and
extends eastwards through the Malay Archipelago as far as New Ireland,
where it is associated with _Melonycteris melanops_, distinguished by
its larger size and the total absence of the tail. An allied small
_Carpopycteris_ inhabits India. _Trygenycteris_ (_Megaloglossus_)
_woermanni_, of West Africa, is the only member of the group occurring
west of the Himalaya. _Callinycteris_ of Celebes, with the dentition
_i._ 2/2, _c._ 1/1, _p._ 2/2, _m._ 3/3, has a short tail and no
index-claws, while _Nesonycteris_ of the Solomons, with the dentition
_i._ 2/1, _c._ 1/1, _p._ 3/3, _m._ 3/3, differs by the absence of the
tail.

_Microchiroptera._

Insect-eating bats.

The second and larger suborder, the Microchiroptera, includes all the
insectivorous species, the majority of which are of relatively small
size as compared with the Megachiroptera. In these bats, with a few
specialized exceptions, the crowns of the cheek-teeth are surmounted
by sharp cusps, divided by transverse grooves. In the skull the bony
palate narrows abruptly and is not continued backwards laterally
behind the last molar; there is one rudimentary phalange (rarely two
or none) in the index finger, which is never terminated by a claw; the
outer and inner sides of the ear commence interiorly from separate
points of origin; the tail, when present, is contained in the
inte
