Diagnosis Test elongate, broadest in the early triangular to quadrangular or flattened stage, later with nearly parallel sides, and may continue to be triangular or become broadly flattened to somewhat ovoid in section, chamber arrangement obscure from the exterior because of the coarsely agglutinated wall, sectioned specimens show it to be completely uniserial with somewhat overlapping chambers, but the triangular section suggests that it is probably derived from a triserial ancestor; wall coarsely agglutinated, the large grains tending to obscure the septa and chambers externally, with scattered large canaliculi of irregular form and orientation as they are offset by the large foreign particles in the wall; aperture terminal, ovate to slitlike. Holocene; Cuba; Atlantic Ocean: Puerto Rico Trench. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
