Akleistostoma (Akleistostoma) floridana (Mansfield 1931).
83.3 mm, Fossil.
Florida.
A nice complete specimen of this large fossil cowry species. The only data accompanying the shell said Sarasota, so I can reasonably consider the APAC pit as the likely source for this specimen. If you haven't aquired our Florida Fossil Cowries book, now would be a great time to do so!
