_Animal._ As preceding genus.

_Shell._ Very similar to the Serpula, but the organization of the animal
makes it a distinct genus; often found clustered together, and attached
to marine substances; conical, thin, tubular, loosely spiral, aperture
straight, circular, edges sharp and complete, several partitions not
perforated towards the summit, operculum horny and complete. Inhabits
the sandy shores of the W. Indies and Africa. Two species.

                     3. Genus _Delphinula_. Pl. XI.

_Animal._ See Scalaria.

_Shell._ Thick, and pearly in the interior, subdiscoid or conical;
spiral whorls rough or angular, often detached, spiny; large umbilicus,
sometimes triangular; the margins united, mostly fringed or ventricose.
Inhabits the Indian and American seas. Five living species. Seven
fossil.

or dentated on the inner margin of the whorls; aperture not modified by
the last whorl of the spire, which is entirely flat; no columella.

elongated, having the eyes upon a dilation of their external base; mouth
without superior tooth, but furnished with a spiral lingual band.

_Shell._ Marine, found in almost all parts of the world, some smooth,
others knotted, spined, tuberculated, or undulated; thick, generally
pearly, spire sometimes depressed, at others elevated and pointed at the
summit, sharp or carinated at its circumference, frequently umbilicated,
not always; aperture transversely depressed, the margins not united at
the upper part; columella arched and twisted, often projecting forward;
