together in some numbers, and this remarkable and elegant character 

 will readily distinguish it from any other species. 



Cancellaria antiquata. Cane, testa ovatd, acuminatd, contahu- 

 latd, albidd ; anfractibus septenis, pla?iulat}s, costatis, transverse 

 striatis ; costis acutis, superne spinis cavis desinentibus ; apertu- 

 rd trigond ; labro reflexo ; columelld plicis tribus minimis ; um- 

 bilico maxima. Axis 7 lin. 

 Hab. New Guinea ; in twenty-two fathoms, coarse sand. Also ob- 

 tained by Mr. Cuming at the island of Corregidor, Bay of Manila, 

 in seven fathoms, coarse sand. 



A species nearly allied to the singular C. trigonostoma, having a 

 similar relative situation of the whorls to each other, and a very large 

 umbilicus. This is a smaller shell, with a shorter spire, and sutures 

 less profound. 



A letter from Mr. J. E. Gray, addressed to the Curator, was read. 

 This letter refers to some species of Bats from Jamaica, which Dr. 

 Richard Parnell had sent to Mr. Gray. Among these, Mr. Gray ob- 

 serves, are some specimens of the genus Macrotis, a genus which he 

 had recently established upon a Bat from Hayti, showing that this 

 form is likewise extended to Jamaica. 



*• The collection also contains a specimen of Arctibeus Jamaicensis, 

 Leach, and some specimens of a new genus, which is very interest- 

 ing, as being a Noctilionine Bat, with an apparent nose- leaf, bearing 

 a much greater resemblance to the Leaf-nosed Bats {Phyllostomina) 

 than even Mormoops, which, when he first described it, Dr. Leach re- 

 ferred to that group. Indeed at first sight I was inclined to regard 

 the new bat as belonging to the Leaf-nosed Bats ; but on examination 

 I found that the nostrils, instead of being placed on the leaf-like pro- 

 cess, which is the character of that group, were on the under side of 

 the nose- keel, and quite separate from it. 



" This genus may for this reason be called Phyllodia, and it is 

 thus characterized : — 



*' Head moderate ; nose rather produced, with a sharp-edged 

 transverse keel, with the nostrils on the lower side of the keel, and 

 an ovate, lanceolate, fleshy process on the middle of the upper surface; 

 chin with a single, transverse, membranaceous fold, surrounding a 

 triangular group of many small warts ; ears lateral ; tragus distinct ; 

 wings long, rather narrow ; thumb moderate, lower joint rather 

 shortest ; wing from the upper part of the ankle ; interfemoral mem- 

 brane large, truncated ; heel-bone long, strong ; tail enclosed, half as 

 long as the membrane, with the tip above it, and with a vessel from 

 each side of its tip to the hinder margin of the membrane. 



" These characters show that this genus has much resemblance 

 with Mormoops, and especially Chilonycteris, but it differs from the 

 former in having no transverse membranaceous fold on the face, and 

 from the latter, with which it agrees in having a membranaceous fold 

 across the chin, in having a fleshy, erect, leaf-like expansion on the 

 upper surface of the nose, which is wanting in that genus."
