Diagnosis Test with single chamber in early stage, later may be biloculine or multilocular, with chamber arrangement irregular, coiled or uncoiling; wall colorless, transparent, and proteinaceous, without secreted or agglutinated mineral particles; aperture initially with prominent stomostyle and collar, but later may have more than one aperture, and the aperture may become a simple tubular opening. Holocene. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
