Diagnosis Test free, low trochospiral, chambers ovate, increasing gradually in size as added, sutures gently curved, periphery rounded; wall light brown in color, finely and sparsely agglutinated on a proteinaceous base, the early whorl darker brown and with very little agglutinated material; aperture interiomarginal, at the end of a siphonlike lobe projecting from the umbilical margin of the chamber and directed forward, and as the succeeding chamber overlaps the former aperture it remains as an intercameral foramen, opening into the umbilical lobe of the later chamber. Holocene; Caribbean, W. coast of Trinidad. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
