Diagnosis Test ovoid in outline, robust, chambers one-half coil in length and laterally strongly overlapping the earlier parts of the test, chambers added in planes separated by gradually increased angles, so that they appear in section to form a sigmoid series; wall calcareous, porcelaneous; aperture at the end of the final chamber, largely covered by a broad flap that attaches at its base to the preceding chamber. Holocene; N. Pacific. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
