Abstract

Bolli (1950) distinguished four successively developing 'subspecies' within Globorotalia fohsi (s.l.) which he used for the subdivision of the zone of Cushman and Stainforth (1945) in the late Tertiary Cipero Formation of Trinidad; correlations were later extended to many other parts of the world. The new species Globorotalia (Turborotalia) peripheronda, G. (T.) periferacuta, G. (Globorotalia) praefohsi are here proposed for forms preceding G. (G.) fohsi in progressive development of the imperforate carina; stratigraphic succession is shown to follow this lineage. Variations in the perforate pseudo-carina, used as criteria by Bolli, have no direct relation to stratigraphic horizon. G. barisanensis differs from G. fohsi only in the latter characters, so is considered a junior synonym.
