ZOOLOGICAL SOCIETY. 



February 28, 1843.— 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 Hystricidce, 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 : — 



Chilonycteris fuliginosus. Chi. supra fuliginosus,fusco-tinctus, 

 suhtus fuscescens, guld femorihusque 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 cf 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 Rhinopoma of India and Africa. The large size of the ears sug- 

 gests for this genus the name 



Macrotus. 



Ears large, lateral, slightly plaited, united over the head by a rather 

 high transverse membrane. Tragus elongate, acute ; lobule broad 

 and divided from the conch by a slight nick. Nose-leaf lanceolate, 

 erect ; the front margin distinct. Lower lip with a narrow, tri-
