REMARKS ON VIRGINIA EOCENE FOSSILS

The following notes and descriptions are based on material
by members of the first cruise of the Ianthina in Vir-

collected

Most material, then new, has been subof the Maryland Geological Survey and interesting geographic data on the Virginian beds have
been published by members of the Survey of that State. However, these few additional notes seem worthy of publication.
