Diagnosis Early stage irregularly enrolled, probably streptospiral, later planispiral, with welldeveloped septa and chambers, final chambers uncoiling and rectilinear; wall calcareous, microgranular to granular, single layered or with a slight tendency toward differentiation; aperture areal, at least in the final whorl and terminal in the uncoiled portion. U. Devonian (Fammenian); France. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
