Ringicella is a genus of tropical air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Odontostomidae.
Adult snails of this genus have an extremely unusual shell morphology, very similar to that found in the genus Anostoma Fischer von Waldheim, 1807, of which this genus was previously considered to be merely a subgenus.
The adult snails in this genus carry their shells upside down, with the spire or apex at the bottom, and the umbilicus at the top.[1]
