Diagnosis Test large, flattened, early stage in a low trochospiral coil, later becoming nearly planispiral and bievolute but not symmetrical, about two and a half rapidly enlarging whorls, increasing from about five to seven chambers per whorl in the early stage to eight or nine in the final whorl, sutures depressed, curved slightly back at the periphery, bluntly rounded periphery with imperforate carinal band; wall calcareous, thin, optically granular, coarsely perforate; aperture a low subequatorial arch in the early stage, becoming progressively more asymmetrical in later chambers, a narrow slit beginning perpendicular to the basal aperture and extending obliquely up the apertural face, both slits bordered above by a narrow lip, aperture continuing as a slit along the spiral suture on the umbilical side, the umbilical margin of each chamber bordered with a very narrow protruding flap or lip. M. Miocene (Helvetian), Mohnian; USA: California. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
