Radial inter-chamber dorsal sutures; little lobed spiral sutras; subradial ventral sutures ending in a narrow and shallow umbilicus. All relatively depressed. Umbilical-extra-umbilical opening, a perforated arch. Thin and finely perforated wall. Maximum diameter of the holotype: mm. 0:26. Translated using Google translate from Italian Original text below Observation. - The Globorotalia pseudobulloides (Plummer) of the lower Eocene shows such remarkable resemblance with the species proposed here, that the similarities cannot be ignored, despite the different age. The Eocene species differs from ours only by the less convoluted spire and by the apparently non-perforated lip with a non-jagged edge.
