Notes on the Fauna of the Chipola Formation- XXI a New Species of the Genus Lopha (Mollusca: Bivalvia)

Abstract

The shallower water deposits of the Chipola Formation exposed in the section along Farley Creek eastward from the Chipola River contain many specimens of a relatively small species of the ostreid genus Lopha. All are elongate and most show evidence that they were attached, during life, t o a tubular dasydadacian alga that is common in all collections from that area; a few, however, were attached to small cerithioid and Turritella shells.
