Siphocypraea briani (Petuch, 1996)
Statigraphy: Pinecrest Sand Member of the Tamiami Formation
Location: APAC, Sarasota County, Florida USA.
Notes: Described as Calusacypraea briani and differentiated from S. sarasotaensis by having a larger and longer shell. I have placed this shell as S. briani however it could be a gerontic individual of S. sarasotaensis. Some Cypraeidae demonstrate sexual dimorphism which could explain the larger size as well. WoRMS classification Siphocypraea, Petuch Calusacypraea.
