Diagnosis Test: small, conical, with an early trochospiral coil of about four chambers per whorl, later with three or only two broad, low chambers per whorl around a continually widening umbilicus, final chamber occupying up to three-fourths of the test circumference, a strong umbilical flap from the final chamber extends over the umbilical area and covers similar flaps from previous chambers to form a lamellar central region; wall agglutinated, outer wall strongly canaliculate, but apertural surface solid; aperture from the chamber opening into the central region beneath the umbilical flap. Paleocene (Montian); Netherlands; Belgium. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
