taxon was established for mostly conispiral, but also discoidal and
auriform (ear-like) shells which have a nacreous, aragonite, inner layer.
Kaynak: PleurotomariaceaThe paucispiral shell is umbilicated,
auriform and depressed. The entire aperture is oblique. It has a simple columella , and a rounded,
Kaynak: TornidaeThe aperture is
auriform, moderately large, and oblique. The posterior angle is acute, slightly channeled at the junction of the outer lip
Kaynak: Cossmannica aciculataThe shell is oval-
auriform, depressed, and rugosely striate. It has a thin, readily deciduous epidermis. The apex is minute, very short
Kaynak: Shelled slugThe shell is small, rudimentary,
auriform (ear-shaped) and is situated far back on the animal. The shell is incapable of containing the

Kaynak: Aperture (mollusc) The shell is thin, mostly external, calcareous,
auriform, paucispiral and invested by a velvety epidermis . The spire is lateral and

auriform (ear-shaped) with a wide aperture to the long, slender forms of typical top shells. The internal shell is
Kaynak: TrochidaeThe shell is rudimentary,
auriform, thin, opaque, oval, increasing irregularly. The protoconch is first smooth, then spirally grooved.
Kaynak: Schizoglossa novoseelandicaThe aperture is sublunate or
auriform, without teeth or folds, height two-fifths to one-third that of shell. The peristome is expanded
Kaynak: AmphidromusThe last whorl (known as the body whorl ) is
