William Horton Lloyd, Esq., in the Chair. 
A letter from J. E. Gray, Esq., addressed to Mr. Waterhouse, was 
read, containing an account of two new species of Bats, a species of 
the family Hystricide, and a new Manis. 
The two specimens of Bats to which Mr. Gray’s observations 
refer, are from Hayti, and were presented to the Society by J. N. 
Tweedy, Esq., Corresponding Member. 
One, Mr. Gray observes, constitutes a second species of the genus 
Chilonycteris, which he had founded upon some specimens brought 
from Cuba by W.S. Macleay, Esq.*, and agrees in almost every 
particular with Chilonycteris MacLeayi, but differs from the three 
specimens of that species contained in the collection of the British 
Museum in being of a much darker colour, and in having the ears 
larger and rather narrower. The principal characters are as follows :— 
CurLonycTeErts FuLieinosus. Chi. supra fuliginosus, fusco-tinctus, 
subtis fuscescens, guld femoribusque ad basin rufescentibus ; au- 
ribus elongatis, attenuatis, acutis.

The second species, Mr. Gray remarks, is more interesting, since 
it proves to be a new genus, readily characterized by the size and 
structure of the ears, and the length of the tail. It agrees most 
nearly with the genus Macrophyllum, but differs from it in having 
the last joint of the tail produced beyond the edge of the large trun- 
cated interfemoral membrane; the tail in the species of the genus 
last mentioned only extending to the edge of the membrane. An- 
other important difference consists in the large size of the ears and 
their union on the upper surface of the head—a character which is 
the more remarkable, since it affords an exception to the rule which 
has hitherto been general, viz. that the Bats with a simple nose-leaf 
(Phyllostomina), which are inhabitants of the New World, have the 
ears separate and confined to the sides of the head, whilst those 
found in the Old World have them united as in this genus from 
Hayti, which thus unites the Glossophagine genera of this tribe with 
the Rhinopome of India and Africa. The large size of the ears sug- 
gests for this genus the name ,
