Ringiculidae are a family of small deep water sea snails, marine gastropod mollusks or micromollusks in the informal group Lower Heterobranchia.[1] [2]
Ringiculidae is the only family within the superfamily Ringiculoidea.
The shells of species in this family superficially resemble minute versions of the shells of the Cassinae.
Characteristics
[edit](Original description in German) The shell is generally spherical, though in rare cases, it can be an elongated oval shape. Its aperture is crescent-shaped and lacks both a siphonal canal and a notch. The outer lip is typically thickened and reflected, while the columella is folded. This family is distinguished from Marginella and related genera by the absence of a notch at the base of the aperture; it differs from the Bullidae by its thickened outer lip. [3]
