Diagnosis Test free, trochospiral, spiral side flattened to concave, umbilical side convex, periphery angular, commonly the peripheral margin of the chambers is slightly elevated on the spiral side, the elevated radially spiralling septa giving the test a sculptured appearance; early chambers tiny, those of the later whorls enlarging rapidly as added, about three whorls present, sutures arched and curved backwards at the periphery on the spiral side, radial on the umbilical side; wall thin and finely agglutinated, commonly with preserved organic lining, exterior with roughened surface and sugary appearance and may include platey fragments that lie flat on the surface to form a pavement; aperture an elongate extraumbilical slit, beginning about halfway between the periphery and the umbilicus, and extending along the base of the apertural face nearly to the umbilicus. U. Cretaceous; USA: Texas, Arkansas. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
