JMICROCHIROPTERA 655 
the smallest known species of the suborder, being much smaller than 
the common Noctule Bat of Europe, and its forearm scarcely longer 
than that of the Long-eared Bat. It is nearly as common in certain 
parts of India as Cynopterus marginatus (compared with which it is 
proportionally equally destructive to fruit), and extends eastward 
through the Malay Archipelago as far as New Ireland, where it is 
associated with Melonycteris melunops, distinguished from it by its 
larger size and the total absence of the tail. , 
Nesonycteris..—Dentition : 2 2,¢ 4, p 3, m2; total 32. Allied to 
Melonycteris, but distinguished by the absence of the inner pair of 
lower incisors, and of a claw to the index finger. Tail wanting. 
Represented by VV. woodfordi, of the Solomon Islands. 
Callinycteris.°—Dentition: 7 3, ¢4, p 3, m 3; total 32. Allied 
to the preceding, but with a short tail; no claw to index. One 
species from Celebes. 
Trygenycteris2=—Dentition: i2,¢ 4,p 3%, m 3; total 34. No 
external tail; a claw on index. One species from West Africa. 
HH 
Suborder MICROCHIROPTERA. 
Insectivorous (rarely frugivorous or sanguivorous) Bats, of com- 
paratively small size. Crowns of molars acutely cusped, marked 
by transverse grooves ; bony palate narrowing abruptly, not con- 
tinued backwards laterally behind the last molar ; one rudimentary 
phalanx (rarely two phalanges or none) in the index finger, which 
is never terminated by a claw; outer and inner sides of ear-conch 
commencing inferiorly from separate points of origin; tail, when 
present, contained in the interfemoral membrane, or appearing upon 
its upper surface ; stomach simple (except in the Desmodont Phyl- 
lostomutidw); Spigelian lobe of the liver very large, and the caudate 
generally small.. Inhabit the tropical and temperate regions of 
both hemispheres. The members of this suborder may be divided 
into two sections. 
Section VESPERTILIONINA. 
Tail contained within the interfemoral membrane; the middle 
pair of upper incisors never large, and separated from each other 
by a more or less wide space. Middle finger with two osseous 
phalanges only (except in Myxopoda aurita, Thyroptera tricolor, and 
Mystacops tuberculatus). First phalanx of the middle finger extended 
(in repose) in a line with the metacarpal bone.
