Species Globorotalia whitei Weiss 1955

Diagnosis / Definition:

Bolli (1957):
Shape of test very low trochospiral, umbilical side inflated; equatorial periphery lobate; axial periphery rounded to subacute. Wall calcareous, perforate, finely spinose. Chambers inflated, slightly compressed laterally; about 12, arranged in 2-2 1/2 whorls, the 4-5 chambers of the last whorl increasing moderately in size. Sutures on spiral side oblique, depressed; on umbilical side radial, depressed. Umbilicus fairly narrow, open. Aperture a low arch; interiomarginal, extraumbilical umbilical. Coiling random. Largest diameter of figured hypotype 0.33 mm.

Discussion / Comments:

Bolli (1957):
Globorotalia whitei Weiss appears to be the ancestor of G. wilcoxensis Cushman and Ponton. From that species it is distinguished mainly by its smaller size and less acute axial periphery.
