one is entire j the lower lias a deep notch in the centre, which is 

 bald, triangular, and edged with a series of close, short, rounded 

 warts. The tongue is elongated, and is closely and minutely 

 warty. 



" The wings are large and broad. The thumb is long, two-jointed, 

 free and sharply clawed; the index finger is composed of two, and 

 the middle of four, bony joints. 



" The interfemoral membrane is rather large, and is deeply notched 

 behind. 



" The tail is rudimentary, consisting of a single joint imbedded in 

 the base of the interfemoral membrane. It has, in the female, a 

 slight cartilaginous band extending beyond its tip, and separating 

 behind into two diverging bands, one extending to the middle of each 

 shin: in the male, these bands are distinct at their origin. 



" The hinder feet are large ; their toes are nearly equal, and are 

 strongly clawed. 



•' This genus agrees with Glossophaga in most of its characters, 

 and has the same warty-edged slit on the middle of the under lip, and 

 the same elongated tongue : but it differs in the form and structure 

 of the nose-leaf; in the tongue being covered with rough and closely 

 set warts, which are not placed, as in that genus, in oblique plaits ; 

 and in the shape of the central upper incisors, which are elongated 

 and conical, and not short and flat-topped and bevel-edged. In the 

 form of its upper middle incisors it agrees with Vampyrns soricinus, 

 Spix; but it is distinguished from that, and from all the other Vam- 

 pyri, by the structure of its under lip and tongue, and by the hinder 

 part of the nose-leaf being separated by a groove from the skin of 

 the forehead. Its interfemoral membrane is somewhat like that of 

 Vamp. Spectrum, Geoff., and has the same muscular bands.

" The nose-leaf is oblong, transverse.notched and elevated behind. 

 The tragus is triangular, elongated, crenulated on its outer and upper 

 edge and 3-lobed. The face is rather bald in front, with scattered, 

 rigid hairs ; and there is a large convex wart, covered with rather 

 rigid hairs, on the back part of the cheek just under the eyes. The 

 wings are dark brown and hald; their front part and index fingers 

 yellow, with a few scattered hairs on the outside of the thicker part 

 near the loins and hinder members. The male is bay above, with 

 the tips of the hairs darker; beneath it is pale yellowish bay. In 

 the female the neck and wings are rather paler. 



" This Hat inhabits caves in St. Vincent's according to the late 

 Rev. Mr. Guilding, who proposed to call it Vesperlilio Cavernarum.' 



Mr. Gray exhibited a drawing of a Shell, contained in the col-

 base of the Parremo, near the Volcano of Tolyma, on the cast slope
