Diagnosis Test elongate, megalospheric test subcylindrical with broadly rounded base, microspheric test slightly flaring from the narrow base, circular to oval in section, triserial in the early stage, later biserial, sutures slightly depressed to flush, oblique; wall calcareous, optically granular, finely perforate, surface smooth; aperture an elongate slit extending from the base of the final chamber up the face, across the top, and about halfway down the opposite side, both margins poreless, one margin being curved inward and the opposite one projecting above like a narrow hood, bordered with a narrow rim. Holocene; N. Atlantic; E. Gulf of Mexico. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
