 {Appun, 4, sub i. grandifiora) ; v.fruct. in Mus. £rit.j Guiana [Appun).

 4^5 lines long, and have about 12 pairs of nerves, arcuately conjoined near the margin. 

 The pyxidium (Plate LIY.) is 8| in. lon^, mucb constricted and sulcated near the base, 

 suhcylindrical and 6-sulcate belovp- the calycary zone, which is 4^ in. above the base, and 

 projects 1 in. all round, being there sbarply bexangular, acute at the thickly tumified 



gles, the lobes, 1 J in. tbick, being connected by a sharp linear ridge ; the interzonal 



band ascends from the lobes in ogival form, and is 2 in. high ; the superior zone is Sj in. 



having within it a nearly horizontal mouth, contracted at its sharp edge to 



diameter of IJ in, ; the operculum, pulvinate at its base, is 3| in. broad, and Ij in high 

 with a thick flattened convex summit.
