Test auriculate in outline, somewhat compressed and biconcave, resembling Alliatina but distinctly trochospiral, small accessory chambers developed over the sutures on the umbilical side, reflecting the position of attachment of the internal partition, asymmetrical internal partition of inverted V shape, crossing the chamber obliquely to attach to the interior wall of the septal face where its position is marked externally by a groove from the areal opening to the proximal chamber margin near the umbilicus, then extending back to attach to the base of the previous septum, sutures distinct, white in color, later ones slightly depressed, periphery broadly rounded; wall aragonitic, finely perforate, lamellar; aperture a low interiomarginal and equatorial slit, with a rounded areal aperture as in Alliatina but slightly offset toward the umbilical side, aperture sealed in the final chamber by a thin calcareous plate that is resorbed when new chamber is added to leave a functional areal foramen. Pliocene to Holocene; England, Italy; Pacific: Philippine Islands; off Mexico. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification)
