The foot is proportion-ably small, and the tentacula support theeyes upon a lateral peduncle larger eventhan the tentaculuin itself. The operculumis horny, lon;^, and narrow, resting upon athin tail. Pteroccraa, Lam., have the mar-pin of the full-grown shell divided into long,slender digitations, varying in number ac-cording to the species. The animal is thesame as in Strombus. Other Strombusidie have the sinus con-tiguous to the siphon. These are the Roi-tellaria, Lam. They have generally a secondcanal mounting up the spire, and formedby the external lip, and by a continuationof the columella. In some of them the lipis digitated. Their animal resembles thatof the MuricidK ; but the operruium is verysmall. Others have merely denticulationson the lip : their canal is long and straight.Others have the margin entire and plane;and these are the Uijipocrcties, Montf.

Thus they have not organs ofcopulation, and must fecundate themselves. Vermetus, Adanson,—lias a tubular shell, whose whorls, at an early age, still form a kind of spire; but they are continued onin a more or less irregularly twisted or bent tuhe, like the tubes of a Serpula. The shell usually attachesitself by interlacing with others of the same species, or by becoming partially enveloped by lithophytes.The animal, having no power of locomotion, is deprived of a foot, properly so callcil; but the partwhich in ordinary Gasteropodcs forms the tail, is here turned under, and extepds forwards, even beyondthe head, where its extremity becomes inflated, and furn
