As now defined and characterized by Lamarck, is easily distinguished by
not having the winged aperture on the right side dentated or digitated,
and the sinus therein always separated from the canal.
In some species the exterior is variously striated, smooth, wrinkled
longitudinally, or tuberculated; the interior presents vivid and
beautiful colours.
These shells frequently attain a large size and great solidity.
Shell thick, sub-involute, diconic, or ventricose, terminated like a
cone before and behind; aperture very long, narrow, terminated
anteriorly by a canal more or less elongated, recurved; the edges
parallel; the external dilating with age, offering behind a gutter at
its attachment to the spire, and before a sinus more posterior than the
canal, through which passes the head of the animal; operculum horny,
long, and narrow, with elements as if imbricated; the summit terminal.
