Diagnosis Test attached, encrusting, early chambers clustered in raspberrylike arrangement, followed by a few whorls of somewhat larger chambers, later chambers more irregular, elongate and vermiform in outline as seen in horizontal section, spreading over the substrate as in Acervulina, those of successive layers neither aligned nor regularly alternating in position, chambers of a single layer connected by intercameral stolons through the vertical walls, chambers of successive layers connected by fine pores; wall calcareous, with occasional solid pillars embedded in the roof of nepionic chambers; aperture consisting of the lateral stolons and surface pores. Miocene; N. Pacific: Saipan Island. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
