Diagnosis Test small, commonly 100µm to 120µmin diameter, with rounded to ovoid proloculus, later may become biloculine or multilocular, and chambers may be trochospirally enrolled or uncoiling or irregularly arranged; wall colorless, membranous, transparent, proteinaceous; aperture terminal, rounded, may have pronounced neck and prominent entosolenian tube; pseudopodia granular, filose and reticulose; multinucleate, nuclei about 6 µm in diameter; both unilocular and multilocular individuals may produce abundant amoeboid gametes and undergo sexual reproduction. Living specimens may be deeply buried in accretionary mass of debris and food particles. Holocene; intertidal region; USA: Monterey Bay, California.
