"The present paper deals with a study of the planktonic foraminiferal fauna of the Roesnaes clay of Denmark and the lower Eocene 3 facies of northwestern Germany (the so called London clay facies) . . . . Tentative correlation is made with the lower Eocene of the Gulf Coast (G. rex zone), the upper Lizard Springs formation (G. rex-G. aragonensis zones) of Trinidad, and the lower Eocene marls (zone of conical Globorotalia) in the eastern section of the northern Caucasus and similar sections in the Soviet Union. . . . Fifteen species are recorded of which one, Hastigerina eocenica, is new.".
