Diagnosis Test free, large, up to 2.9 mm in greatest breadth, chambers in a low trochospiral coil, about five in the first whorl, increasing very slowly in height but rapidly in breadth so that later whorls have more chambers, the increased height of the spire resulting in an auriculate test, spiral side strongly convex, umbilical side flattened to concave, with broad umbilicus, chamber lumen open and undivided, sutures strongly curved on the spiral side, nearly radial on the umbilical side, internally the septa thicken toward their umbilical ends; wall agglutinated of calcareous particles, canaliculate; chambers opening into the umbilicus that is covered by a prominent umbilical apertural flap, growing continuously in a corkscrewlike spiral from an early stage, with successive attachments to the umbilical margin of each chamber of the final whorl, flap pierced by large pores in the center as well as at the edges. M. Eocene; USA: Florida. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
