Diagnosis
ReferenceDiagnosis
H. M. Bolli 1957Shape of test very low trochospiral, biconvex, moderately compressed. Equatorial periphery lobate. Axial periphery rounded. Wall calcareous, perforate, surface smooth. Chambers moderately compressed; 12-15, arranged in 2-2.5 whorls. The 5 chambers of the last whorl increase fairly rapidly in size. Sutures on spiral side curved, less so in the last chambers, depressed; on umbilical side radial, depressed. Umbilicus fairly narrow, open. Aperture a low arch with a lip; interiomarginal, extraumbilical-umbilical. Coiling random in the Globorotalia trinidadensis and Globorotalia uncinata zones. A prreference for dextral coiling (up to 75 percent) develops in the Globorotalia pusilla pusilla zone. Largest diameter of figured hypotype 0.35 mm.
