Original Description
Extra details from original publication
Distribution: G. exumbilicata is abundant in the shallow Northwind Escarpment and in Alpha Rise sediments deposited during the Matuyama epoch. In earlier publications (Herman 1970a; Herman et al., 1971) and in Figs. 2 and 14 this species was included with the counts of G. quinqueloba and was also referred to as Globigerina sp., cf. G. quinqueloba.
Editors' Notes
Herman 1980 argued that this was a junior synonym of Globigerina quinqueloba egelida Cifelli & Scott 1970:
" In 1970, Cifelli and Smith established a new planktonic foraminiferal subspecies, Globigerina quinqueloba egelida (p. 32-34, PI. 3, figs 4-6). This taxon, present in plankton tows collected in the North Atlantic exhibits peak development in the western "Slope Waters" during winter and in the subarctic region during the summer. In 1974, the writer published an article in which a new planktonic foraminifer, Globigerina exumbilicata was described from Arctic Ocean basin Pleistocene and Pliocene sediments. Subsequently, Dr. Cifelli sent me specimens from his plankton tow collection which were examined under scanning electron microscopy. It appears that Globigerina exumbilicata Herman, 1974, is identical to Globigerina quinqueloba egilida Cifelli and Smith 1970, and the latter name has priority."
