Mollusks

Shell ear-shaped, pearly, recurving, very depressed, more or less oval,
with spire very small, very low, almost posterior and lateral; aperture
as large as the shell, with margins continued; the right thin and sharp,
the left flat, enlarged, and sharp; a series of holes, complete or
incomplete, parallel to the left margin; one large oval muscular
impression.

                            Haliotis Midæ.
                            H. iris.
                            H. tubifera.
                            H. excavata.
                            H. Australis.
                            H. tuberculata.
                            H. striata.
                            H. asinina.
                            H. glabra.
                            H. lamellosa.
                            H. unilateralis.
                            H. rugosa.
                            H. canaliculata.
                            H. tricostalis.
                            H. dubia.

_H. asinina._ The asinine Haliotis.

Internal margin very broad, inside pearly, smooth, shining, iridescent,
reflecting green, pink, and orange; back clouded with brown and green;
striated longitudinally.

_H. costata._ The ribbed Haliotis. Pl. 22, fig. 4, interior. Pl. 32,
fig. 6, exterior.

Species with disk rounded anteriorly.

_H. canaliculata._ The channelled Haliotis.

Species with disk elevated by a large parallel rib, hollowed interiorly,
and with the anterior margin more or less irregular.

_H. tuberculata._ The tuberculated Haliotis.

Aperture open the whole length of the shell; outer lip irregular,
exterior reddish brown, striated longitudinally and wrinkled
transversely, with a few raised tubercles; interior pearly, reflecting
the most beautiful shades of pink, blue, green, and yellow.


                              FAMILY XIII.
                         PLICACEA. Two genera.


                      1. Tornatella. Six species.

Shell thick, oval, convolute, the spire very short; the last whorl much
larger than all the others united; the external thin, sharp, dentated
interiorly; one or two large plaits on the columella, of which one
serves to separate the two parts of the foot.

                          Tornatella flammea.
                          T. solidula.
                          T. fasciata.
                          T. auricula.
                          T. nitidula.
                          T. pedipes.

_T. fasciata._ The banded Tornatella.

Spire produced, apex acute, aperture straightened, with one plait on the
columella; finely striated transversely, with two white transverse
bands; colour purplish red.

_T. coniformis._ The cone-shaped Tornatella. Pl. 22, fig. 3.

Species like a cone; the spire entirely flat.


                     2. Pyramidella. Five species.
