Mollusks

Shell simple, conical, depressed, recurved; summit perforated a little
anterior in an oblong or oval manner, like a keyhole; the exterior
surface ribbed longitudinally, slightly striated transversely.

                           Fissurella picta.
                           F. nimbosa.
                           F. crassa.
                           F. Græca.
                           F. nodosa.
                           F. Cayennensis.
                           F. lilacina.
                           F. rosea.
                           F. Barbadensis.
                           F. radiata.
                           F. viridula.
                           F. hiantula.
                           F. pustula.
                           F. fascicularis.
                           F. Javanicensis.
                           F. depressa.
                           F. Peruviana.
                           F. gibberula.
                           F. minuta.

_F. nimbosa._ The scaly-ribbed Fissurella.

Species of which the middle part of the edges of the aperture is
hollowed in such a manner that, when placed on a level surface, they
touch only at the extremities.

_F. rosea._ The rosy Fissurella.

Species more depressed, edges bent up lengthwise, forming a kind of
canal.

_F. Græca._ The Greek Fissurella. Pl. 32, fig. 1.

Conical, ovate oblong; striæ cancellated and elevated; sections
tuberculated; exterior yellowish brown or clouded, interior white or
light blue.


            4. Pileopsis. The Caplike Limpet. Four species.

Easily distinguished by its form, which gave rise to the common name.

Shell oblique, sharp pointed; cone bent forward, with a recurved, almost
spiral summit, finely striated longitudinally and slightly wrinkled
transversely; aperture a round oval; the margin at the base nearly
round, more or less regularly crenated and indented, interior with a
lengthened, arched, transverse muscular impression.

                          Pileopsis ungarica.
                          P. mitrula.
                          P. intorta.
                          P. subrufa.

_P. ungarica._ The Fool’s Cap.

Conical, vertex slightly spiral, pointed, and recurved; exterior pale
fawn colour, and the outer margin bordered with a fringed epidermis;
interior sometimes of a very bright pink or rose colour.


         5. Calyptræa. The Cup and Saucer Limpet. Four species.

This genus of shells is remarkable for having in the interior cavity a
transverse funnel or tongue-shaped testaceous appendage, from which
originated its common name.

Shell conic, base orbicular; summit vertical and imperforated; cavity
deep, having at its interior summit a tongue-like appendage. This
appendage is sometimes vertical and sometimes like a horseshoe, having
on it a muscular impression of variable form.

                        Calyptræa extinctorium.
                        C. lævigata.
                        C. equestris.
                        C. tectum-sinense.
