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.
