Despite their widespread occurrence as fossils and as part of the present marine benthos, lepadomorph barnacles have been known heretofore in the Gulf Coast Tertiary from only five Eocene species. These usually comprise dissociated valves of distinctive shapes and ornamentation whose assignment to genera and species involves determining the number as well as the morphology of the valves. Lepadomorphs have potential value stratigraphically not only as guide fossils but also as indicators of bathymetry. Although living stalked barnacles as a group range from benthic to epipelagic and from intertidal to abyssal, most genera have rather narrow tolerances and seemingly prefer deep water. Two new species, Aporolepas howei and Euscalpellum? latunculus, are here introduced.
