Original Description Test small, about 80 µm, low trochospiral, chamber subglobular, increasing rapidly, four chambers in the final whorl, wall smooth to weakly pustulate, rarely with pore mounds, aperture elongate, extraumbilical-peripheral, or extending to the upper part of the apertural face, with or without a thin lip. Size: Test small, about 80 µm Etymology: Extra details from original publication Remarks. This species is proposed to include forms which have been widely misidentified as Globigerina fringa by several workers. Studies of Russian material by the Palaeogene Planktonic Foraminifera] Working Group, however, indicate that G. fringa belongs to the cancellate group (Olsson, 1992, pers. comm.) and should be considered a species of Eoglobigerina (Berggren, 1992). See above for notes on these two species. Editors' Notes
