Diagnosis Test predominantly dextrally coiled in a high trochospiral, numerous broad and low chambers subdivided by transverse partition formed by infolding of the outer wall, sutures oblique, slightly depressed; wall aragonitic, hyaline, optically radial, very finely perforate, surface smooth; aperture elongate, looplike, extending up the face of the final chamber, a small supplementary triangular opening on the opposite side of the test at the junction of the inner partition and previous septum, supplementary openings of earlier chambers closed as a new chamber is added. Paleocene to Holocene; Europe; North America; New Zealand; Atlantic; Pacific; Arctic; Antarctic. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
