Mollusks

_Animal._ Unknown.

_Shell._ Oval, and, as it were, depressed by the preservation of each
side of a longitudinal thickened band; aperture oval, almost symmetrical
by the excavation of the columellar edge, terminating anteriorly by a
short canal, often a little sloping; a sinus at the posterior junction
of the two edges. This genus forms a distinct division between the Murex
and Struthiolaria. Inhabits the Northern and Mediterranean Seas. One
species is found in America. Fifteen living species. Five fossil.

                       10. Genus _Murex_. Pl. XI.

_Animal._ See _Pleurotoma_, above.

_Shell._ Usually oval; the spire but slightly elevated, roughened with
longitudinal, transversal bands or varices; aperture small, quite oval,
and symmetrical by the excavation of the left edge, formed by a lamina
applied upon the columella, terminated anteriorly by a middling canal
sometimes very long and closed; the right edge more or less furnished
with varices. Operculum horny, complete, oval, nearly circular, with
sub-concentric partitions; summit terminal. This genus comprehends only
such shells as have only three or more varices on each whorl. These
varices show how often the animal has increased the size of its shell.
