Diagnosis Test enrolled, discoidal, and biumbilicate, with plane of coiling oscillating in the early stage, later nearly planispiral and evolute, about eight chambers in the final whorl, periphery rounded but slightly truncate in the later chambers, septa short and follow the curvature of the chambers; wall calcareous, microgranular, thick, undifferentiated, with agglutinated particles; aperture simple and basal in most of the test, becoming multiple and areal in the last one or two chambers. L. Carboniferous (M. Visean); England. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
