Notes on the Fauna of the Chipola Formation- III Two New Species of Vasum (Mollusca: Gastropoda), With Comments on Vasum Haitense (Sowerby)

Abstract

When the writer (Vokes, 1966) published a monograph on the genus Vasum in the western Atlantic there were two species of Vasum known from the Chipola Formation of northwestern Florida. Since then, additional collecting has revealed two new species in this formation, plus many more and better examples of one of the previously described forms, Vasum haitense (Sowerby).
