Further Comments on Hexaplex Fulvescens (Sowerby) and Hexaplex Hertweckorum (Petuch) (Mollusca:Gastropoda)

Abstract

In my original discussion (Vokes, 1968, that there must be post-Pliocene beds exp. 104) of Hexaplex fulvescens (Sowerby, 1834), I noted that the species "first appears in the upper Miocene Beds of southern Florida. It is never exceedingly abundant but it is well represented at several different Miocene localities in the vicinity of Lake Okeechobee." As we now know, the Pinecrest Beds ( = Fruitville Formation of Waldrop and Wilson, 1990) are middle Pliocene and not "Miocene."
