Busycon maximum is a geographically widespread shell found only in the Upper Pliocene of the Southeastern United States. Form alumense from the Florida Panhandle differs from B. maximum found in the Sarasota shell pits by lacking shoulder knobs and in having a more compacted spire.

Order Trocida Family Calliostomidae Calliostoma mitchelli philanthropus (Conrad, 1834) Statigraphy: Pinecrest Sand Member of the Tamiami Formation Location: SMR Phase 10 Pit, Sarasota County, Florida USA. Status: Extinct Notes: This top shell displays quite a bit of variation. Conrad (1834) described both C. mithchelli and C. philanthropus. Later authors such as Dall (1892) and Mansfield (1930) placed several subspecies within C. philanthropus. Of 30 Calliostoma species/subspecies from the Upper Pliocene, Campbell (1993) recognized 19. Two stocks were dominate C. virginicum and C. mitchelli which took page precedence over C. philanthropus and which former subspecies are now named.
