Thirty-one species of Foraminifera, of which 29 are new, are described from the Washita group (Lower Cretaceous) of southern Oklahoma and northern Texas. Four new genera are described, Polychasmina, belonging to the Reophacidae, Meandrospira of the Ophthalmidiidae, Acruliammina of the Placopsilinidae and Planomalina, a new member of the Anomalinidae. The geologic range of three genera, Nodophthalmidium, Ophthalmina and Eouvigerina, is extended downward to include the Lower Cretaceous.
