Original Description
“Test elongate compressed, trochoid, periphery, lobulate rounded; wall semihyaline prominently, compactly perforate, comparatively smooth; initial chambers small about three whorls of semiglobose chambers rapidly in creasing in size, four more globose chambers in last formed whorl; primary aperture in form of an arch at base of last formed chamber with one at least secondary smaller aperture at opposite end.

Size: Holotype (fig. 9) .415 x .249 x .217mm; hypotype (fig. 7) .442mm dia. x .332mm.

Extra details from original publication
“The possibility that these are abnormal has been considered. They are rare. If normal forms, the genus is questioned because of the secondary apertures. Globgerina helicina D’Orbigny, 1826, was described as a Recent from Adriatic; Brady (1884, Challenger Exped. 1873-76, Rept., Zool., vol. 9, pl. 81, figs. 4, 5) illustrated two forms which seem to have about the same structure in the views illustrated. The Challenger forms were from deep water, 1125, 1900 fms.”
