Loxacypraea chilona
Taxonomy
Cypraea chilona was named by Dall (1900). It is extant. Its type specimen is USNM 498388, a shell. Its type locality is USGS Loc. 2211 - Alum Bluff, lower bed, which is in a Burdigalian marine marl/sandstone in the Chipola Formation of Florida.
It was recombined as Siphocypraea chilona by Dolin (1991); it was recombined as Cypraeorbis chilona by Darragh (2011); it was recombined as Loxacypraea chilona by Petuch (2004), Landau and Marques da Silva (2010) and Dolin (2015).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| T. A. Darragh 2011 | Petuch stated that a fossula was absent in by the descriptions and illustrations in Dolin and by my own observations of two of the species, Cypraeorbis arlettae and C. wilcoxi (see figs 3H–J, N, K, O). Revision of American taxa is beyond the scope of this paper, but I consider that Floradusta and Loxacypraea are synonyms of Cypraeaorbis, as the type species of each have a fossula similar to C.sphaeroides and C. ventripotens. |
