Dinquosis. — See " Kov/' above, p. 130. 

 bkull. — Frontal sliickl as in Meqaderma. Prenasal notch 

 deeper, measured from the cinguluin of canine about ^ of 

 total length of skull. 



Teeth. — A small p^ present. Cns]-) 3 of in^ moved con- 

 sideiably backward ; tlie posterior triangle (formed by cusps 

 2, 3, 5) at least double the size of the anterior (formed by 

 cusps 1, 2, 4). Cusp 2 moved inward and tending to dis- 

 appear, being represented only by a small tubercle, much 

 below the level of the other cusps. Antero-internal basal 

 ciis]i of upper canine very strongly developed, more so than 

 in Mtgadenna. 



JSuse-leof. — Posterior leaf a rectangle, with slightly convex 

 sides, twice as long as tlie median leaf; median longitudinal 

 ridge (told) as in Megaderma^ but its junction with median 

 leaf forming an obtuse angle on each side, strongly con- 

 Hasting with the sliarply acute angles formed in Megaderma. 

 Eange. — Indian Peninsula; S. Cliina; there seems as yet 

 to be no record of this genus from Burma. 

 Species. — Two, viz. : E. lyra, E. sinends. 

 Hodgson's Eucheira. — Tyjie species, E. schistacea, Hodgs., 

 z= Megaderma lyra, Geoff. The generic name Eucheira was 

 proposed by Hodgson because the " phalangeal system [of 

 E. schistacea] is ap])arently irreconcilable with Cuvier's 

 general and Geoffroy's particular definitions'' of the common 

 structure of the wing in Ciiiroptera; but at the same time the 

 descrij/tion and figure of the wing of schistacea, as given by 

 Hodgson himself, are those of a quite normal I\legadermine 

 •wing, and his schistacea is undoubtedly nothing but the well- 

 known "Megaderma" lyra. Although, therefore, the whole 

 basis en which Hodgson founded the genus Eucheira is a 

 mistake, still the name, as being the earliest in date, will 

 have to stand according to the current nomenclatural rules. 

 The name Eucheira has apjiarently been overlooked by suc- 

 ceeding writers and is not mentioned in Palmer's * index 

 Geneium Manmialium.' 



Peters' Lyroderma. — Type species, Megaderma lyra, Geoff. 

 The characters given by Peters for the " subgenus" Lyro- 

 derma are the shape of the nose-leaf, the flatness of the 

 Irontal shield, and the absence of postorbital processes. The 

 name Lyroderma is antedated by Hodgson's Eucheira.
