The Esna shales are a series of strata that lie at the base of the lower Eocene in Egypt. They contain almost no macrofossils, but the careful study of five widely separated stratigraphic sections has revealed a large microfauna. This, together with Foraminifera from the underlying Cretaceous Chalk and overlying Eocene beds, constitutes a fauna of 168 species and varieties which is listed. Nineteen new species and 17 new varieties are described in this report. Analyses of the relations and ranges of these forms furnish new information on the Mesozoic-Cenozoic boundary in this region.
