_M. episcopalis._ The episcopal Mitre. Pl. 31, fig. 7.
Species turreted, with spiral whorls very wide and entire; the aperture
effuse anteriorly.
_M. papalis._ The papal Mitre.
Species with coronated whorls.
_M. pontificalis._ The pontifical Mitre.
Species covered with a yellowish epidermis, beneath which are
interrupted fillets of orange coloured spots; spire crowned with
tubercles.
_M. micozonias._ The small white-banded Mitre.
Species sub-ovate, spire very short, generally tubercled.
_M. dactylus._ The six-plaited Mitre.
Species oval, spire very short, and generally latticed.
_M. tæniata._ The riband Mitre.
Species flaring, turreted, ribbed; spire more than half the length of
the shell; aperture very narrow, long, sub-canaliculated, with one
plait.
3. Voluta. The Volute or Wreath. 44 species.
This genus, as established by Linnæus, included shells of different
families, promiscuously blended together, rendering it difficult to
determine satisfactorily respecting shells under examination. As
arranged and classified by Lamarck, it is still a numerous and beautiful
genus, containing some of the most rare and costly shells, particularly
V. Junonia or Peacock Volute, of which very few are known. They vary
considerably in size; some are very minute, and others large; they are
found chiefly in the seas of the torrid zone or southern hemisphere.
Shell oval, more or less ventricose; the first whorls of the spire
mamillose; aperture in general much more long than wide, strongly and
obliquely notched anteriorly; the right edge a little reflected, entire;
the columellar edge excavated, and adorned with great plaits, more or
less oblique, and a little variable in number with age.
