Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| H. Bolli 1957 | Shape of test very low trochospiral; equatorial periphery strongly lobate; axial periphery rounded. Wall calcareous, perforate, surface finely pitted, in well preserved specimens with fine, short spines. Chambers strongly inflated, spherical; 10-12, arranged in 2-2K whorls; the 4-4}^ chambers of the last whorl increase rapidly in size. Sutures on spiral side radial, strongly depressed; on umbilical side radial, strongly depressed. Umbilicus fairly wide, deep. Aperture a medium to high arch without lip or rim; interiomarginal, umbilical-extraumbilical. Coiling random. Largest diameter of holotype 0.5 mm. | |
| J. P. Kennett and M. S. Srinivasan 1983 | Test low trochospiral, equatorial periphery strongly lobulate; axial periphery
broadly rounded; chambers spherical, strongly inflated, four to four and one-half rapidly increasing chambers in the final whorl, sutures radial, depressed; surface densely perforated with circular to subcircular pores and elevated circular spine bases (PI. 59, Fig. 2). On early chambers, the spine bases tend to coalesce into regular ridges. Umbilicus wide, deep; aperture a low to medium arch without a lip or rim, interiomarginal, umbilical- extraumbilical. |
