ALATA. Three genera. 1. Genus Rostelluria. Pl. XI. Animal. Entirely unknown. Shell. Subdepressed, turriculated, with a produced and pointed spire ; aperture oval on account of a rather large excava- tion of the columellar edge, the right margin dilating with age, and having a sinus contiguous to the pointed canal which ter- minates the shell; an operculum. This genus is distinguished from the Strombus by having a sinus in the lower part of the right margin contiguous to the canal. Inhabits the European seas. Four living species. Three fossil. Rostellaria curvirostris. Rostellaria pespelicani. R. rectirostris. R. cancellata. 2. Genus Pieroceras. Pl. XII. Animal. See Strombus, below. Shell. Oblong-vate ; canal elongated, attenuated and often closed ; right margin Gilating by age into an expanded digitated wing, attached to and covering a short spire with a sinus in the lower part not contiguous to the body. Distinguished from the Strombus by not having the canal at the base shortened or trun- cated, and from the Rostellaria, by having the sinus of the right CONCHOLOGY. 127 margin distant from the body. Found in the Equatorial seas. Seven species. Five fossil. Pteroceras truncata. Pteroceras chiragra. P. lambio. P. millepeda. , P. scorpio. P. pseudoscorpia. P. aurantia. 3. Genus Strombus. Pl. XII. Animal. Spiral; the foot rather wide anteriorly, compressed posteriorly ; mantle thin, forming a prolonged fold anteriorly, whence issues a sort of canal; head very distinct ; mouth a ver- tical slit at the extremity of a proboscis, provided in the inferior median line with a lingual band having prickles flexed posteriorly ; tentacular appendages cylindrical thick and long, with the eyes at their extremity. Shell. 'Thick, subinvolute, dilated in the middle, terminating in a cone anteriorly and posteriorly ; aperture very long and narrow ; terminated anteriorly by a canal more or less elongated and flexed; edges parallel, the external dilating with age, pre- senting posteriorly a gutter at its point of attachment with the spire, and, anteriorly, a sinus behind the canal, through which the head of the animal passes; operculum horny, long, and narrow ; summit terminal.
