Diagnosis Test planoconvex, trochospirally enrolled, with few whorls and only three chambers per whorl, chambers crescentic and sutures strongly oblique on spiral side, sutures radial and final chamber occupying about one-half the face of the umbilical side, free living in the early stage, some adult specimens attached to the substrate by a spongy calcareous substance or "puffermasse"; wall agglutinated, imperforate; aperture interiomarginal, about midway between the umbilicus and periphery. Holocene; England. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
