Diagnosis Test domelike, median layer of larger chambers parallels the upper surface, covered dorsally by a few tiers of smaller chambers and with ventral hollow of the dome filled with numerous more irregular chambers, median layer with spherical proloculus and annular series of arcuate chambers interconnected by four stolons, two at each end of the chamber, dorsal series of chambers aligned in tiers, appearing quadrangular in transverse section but irregular in horizontal section, ventral chambers arcuate in transverse section and irregular in horizontal section; wall calcareous, that of lateral chamber walls solid and nonperforate, roofs and floors finely perforate. L. Miocene (Aquitanian); Saipan and Tinian, Mariana Islands. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
