Notes on the Fauna of the Chipola Formation- XLII a New Species of Oliva (Omogymna) (Gastropoda: Olividae)

Abstract

The Olivinae of the Alum Bluff Group have been previously reviewed (Drez, 1981) with the description of two new species and one subspecies and the reassignment of previously described species to one new genus and subgenus. Recently during a visit to Tulane University to examine their paleontological collections, a new large species of Olivinae from the Chipola Formation was found in the collections, unlike anything else in the western Atlantic Tertiary.  Further examination of the Tulane collections failed to produce an additional specimen.
