Book Description
Thirty species of Ostracoda from the Yorktown formation and lower beds in the York-James Peninsula of Virginia are described; one species, Murrayina barclayi, is new. The combined ostracode-foraminiferal assemblage of the Yorktown seems to be closer to the Ecphora-Cancellaria facies of the Choctawhatchee formation of Florida, than to any other fauna. A collection of Mollusca, Foraminifera, and Ostracodea made by Dr. Denise Mongin is tabulated and discussed in terms of Mansfield's two Yorktown zones, and the fauna of the Powell's Lake, Virginia, outcrop is confirmed in its St. Marys age by the Mollusk identification of Mongin.
