Diagnosis Test compressed, ovate to flabelliform proloculus followed by second chamber growing in opposite direction, in an incipient tight coil, then uniserial, with a few small rectilinear chambers that increase in length as added, finally followed by elongate adult chambers with a slightly curved axis that each occupy about one-half the test periphery, the bulging basal part of the chambers enclosing the corresponding part of earlier adult chambers; wall agglutinated on an organic base, surface smoothly finished; primary aperture areal, a curved transverse slit near the midpoint of the apertural face, secondary cribrate openings on the bulging proximal end of the adult chambers. U. Cretaceous (Turonian to Santonian): Nigeria; S. Chad; U. Eocene or Oligocene: Colombia; Holocene: USA: Louisiana; Caribbean mangrove swamps in Trinidad, West Indies; Panama; Ecuador, Brazil.
