' If the umbilicus be wanting, they are hi:s LoTORiuM(2). Finally, when the canal is short, the spire elevated, and the varices simple, they are his TRITONIUM. Their mouth is usually plicated transversely on both margins. Very large ones inhabit the seas of Europe(3). The varices a.re sometimes numerous, compressed, and almost membranous, constituting the TROPHONA, Montf.( 4) At other times, they are compressed, very salient, and but few in number(s). M. de Lamarck separates from all the Murices of Brugiere, the RANELLA, Lam., Characterized by opposing varices, so that the shell is bordered with them on both sides. Their canal is short, and their surface studded with mere tubercleg; margins of the aperture plicated(6). The APoLLEs, Montf., are merely umbilicated Ranell::e(7). The Fusus, B1·ug. Comprises all shells with a salient and straight canal, which are destitute of varices. When the spire projects, the columella is without plic::e, and the margin is entire, they are the Fusus properly so called, Lam., which Montfort again subdivides; when they have no umbilicus, they are his Fusus(8).

When provided with an umbilicus they are his LATHIRA(2). The STRUTHIOLARI..IE are distinguished from the true Fusi by a bor-der which surrounds their aperture, and which covers the columella. The margin o[ the adult is inflated, which connects them with Murex(s). When the spire is salient, the columella without plicre, and there is a small indentation or well marked emargination of the margin near the spine, they are the PLEUROTOMA, Lam.( 4) The CLAVATUL..IE, in which the emargination is wide and reaches to the spire, are also properly distinguished. When the spire is but slightly marked, flattened or rounded, and the columella is without plic::e, they are the PYRULA, Lam. Some are umbilicated( s), and others not( 6). From these Pyrulre, Montfort again separates the species with a flattened spire, internally striated near the lip, by the name of FuLGUR( 7). They are a sort of Pyrulre with a plicated columella, the plicre being .sometimes almost insensible. Among these divisions of the Fusi of Brugieres, the FAsoroLARIJ£, Lam., are distinguished by some oblique and well marked plicre on the columella, m~ar the origin of the siphon( B).
