Diagnosis Test free, up to 2 mm in length, irregularly cylindrical, straight to arcuate; wall thin, agglutinated, of very fine sand and mud, poorly cemented and flexible in life, although dried specimens become rigid and fragile, white to dark gray in color, smoothly finished, or may be transversely wrinkled; may have apertures at both ends of the test, one being much smaller than the other, the much constricted openings possibly expand temporarily for the ingestion of food particles but are closed at gametogenesis, and the tiny inequally biflagellate gametes escape from secondarily formed small pores of 15 µm to 20 µm diameter that are scattered over the test surface and then become free swimming. ?L. Pennsylvanian; Permian; Oligocene; Miocene; Holocene, at 100 m to 346 m; S. Atlantic. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
