Extra details from original publication
Remarks: Globorotalia archeomenardii, new species, is distinguished from G. menardii (d'Orbigny) and G. praemenardii Cushman and Stainforth by having a more convex spiral side and in being less lobate. The range in size of the specimens of the new species is very small in contrast to that of the other two species. Typical G. archeomenardii disappear with the first appearance of G. praemenardii. It is probably the ancestor of the G. praemenardii-menardii suite.
