From the album: Gastropods of the Tamiami Formation
Order Littorinimorpha
Family Cypraeidae
Siphocypraea transitoria Olsson & Petit, 1964
Statigraphy: Pinecrest Sand Member of the Tamiami Formation
Location: APAC, Sarasota County, Florida USA.
Status: Extinct
Notes: Although common in the Kissimmee River area, this specimen is from APAC in Sarasota where it is much rarer. Very close to S. problematica with slightly less coiling of the anterior sulcus and a slightly wider posterior aperture. Petuch would call this Siphocypraea streami.
