Diagnosis Test lenticular, compressed, periphery subacute to carinate, chambers biserially arranged, with planispirally enrolled plane of biseriality, commonly four pairs of chambers in the final whorl, alternate chambers extending to the closed umbilicus on one side, leaving only a small triangular portion visible near the periphery of the opposite side, sutures curved; wfill calcareous, hyaline, optically radial, surface smooth and polished; aperture interiomarginal, a long narrow slit along the periphery of the preceding chamber, bordered by a small apertural ridge or lip. L. Pliocene to Holocene; Pacific margins; Caribbean. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
