The genus Tubulostium has been in need of clarification, and as a contribution toward this end four species from the Eocene of the Gulf Province are described. It is concluded that the genus is probably to be placed with the annelids. The generic name is dubious but is retained until a broader study can be made. Of the Cassididae, species belonging to Galeodea and Sconsia are described; of the Ficidae, species belonging to Priscoficus, Perissolax, and Ficus; of the Buccinidae, the new genus Bolis. These forms have a considerable geographic distribution and rather short stratigraphic range and are therefore valuable in wide correlation of deposits.
