Abstract

Ten species from the Richmond Group west of the Cincinnati Arch belong to the genera Foerstephyllum Bassler, Staffordophyllum Bassler, and Calapoecia Billings, of the Order Tabulata, and Cyathophylloides Dybowski of the Order Rugosa. The Waynesville, Liberty, and Whitewater Formations contain respectively one, four, and nine species, with one being common to the Waynesville and Whitewater, and three to the Liberty and Whitewater. New taxa are Foerstephyllum vacuum magnum n. subsp., Staffordophyllum floweri n. sp., and Cyathophyllum wellsi n. sp. Cyathophylloides is emended to include species previously assigned to Favistina (Favistella).
