MICROCHIROPTERA 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 marginatm (compared with which it is 

 proportionally equally destructive to fruit), arid extends eastward 

 through the Malay Archipelago as far as New Ireland, where it is 

 associated with Melonyderis melanops, distinguished from it by its 

 larger size and the total absence of the tail. 



Nesonyderis. 1 Dentition : i f , c }, p f , m f ; total 32. Allied to 

 Melonyderis, but distinguished by the absence of the inner pair of 

 lower incisors, and of a claw to the index finger. Tail wanting. 

 Kepresented by N. woodfordi, of the Solomon Islands. 



Callinyderis.- Dentition : i f, c ^, p f , m % ; total 32. Allied 

 to the preceding, but with a short tail ; no claw to index. One 

 species from Celebes. 



Trygenyderis. 3 Dentition : i f , c ^, p f , m f ; ' total 34. No 

 external tail ; a claw on index. One species from West Africa. 



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 inf eriorly 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- 

 lostomatidce) ; 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. 



Sedion 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 tuber culatus). First phalanx of the middle finger extended 

 (in repose) in a line with the metacarpal bone.
