Original description: Test either Hantkenina-like or distinctly Globigerina- like, almost planispiral to trochoidal. Chambers of Hantkenina type with axially situated spines, those of Globigerina type rounded peripherally, truncate toward umbilicus. Sutures straight to slightly curved in direction of coiling. Apertures large, arcuate, directed toward umbilicus, occasionally with liplike projections. Umbilicus subcircular, as a rule large, deep, with covering plate. Surface ornamented by rugosities of various size and type, either distributed irregularly or arranged in rows radiating from a central point on the surface toward the aperture (meridional pattern).
