Diagnosis Test lenticular, spiral side more convex, with a low trochospiral coil of about three gradually enlarging whorls and seven broad and low chambers in the final whorl, sutures oblique, later ones slightly depressed, chambers subtriangular on the more flattened umbilical side, sutures radial around the shallow umbilicus, periphery subacute, rounded, peripheral outline somewhat lobulate; wall calcareous, coarsely but sparsely perforate, but with imperforate spiral suture, peripheral margin, and apertural lip or may have rare pores on the periphery, surface otherwise smooth; aperture a low interiomarginal equatorial arch bordered by a protruding lip, extending somewhat onto the spiral side, a small part of the proximal end of successive apertures remaining open as relict apertures as new chambers are added. U. Eocene (Priabonian); USA: Mississippi. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
