Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. Todd 1957 | Test small, compactly coiled except for the last formed protruding chamber; height of spire ranges between three-quarters of and equal to diameter of spire. Chambers indistinct, slightly inflated; 4 chambers constituting the last whorl, with a fifth elongate chamber extending downward and at an angle to the axis of coiling. Sutures indistinct, except the last few which are indented. Wall thin, calcareous, perforate, ornamented by a rather coarse cancellation. Aperture large and semicircular or broad and arched at the umbilical edge of the protruding chamber, bordered by a thickened and slightly upturned lip of clear shell material. Diameter exclusive of protruding chamber 0.30-0.37 mm; greatest dimension of test 0.42-0.58 mm. | |
| J. P. Kennett and M. S. Srinivasan 1983 | Test compactly coiled except for the last-formed protruding chamber, low to high spire, chambers indistinct, slightly inflated , four in the final whorl; sutures obscured on earlier chambers due to test thickening, radial to slightly curved on later chambers, slightly depressed. Surface cancellate with distinct pore pits and interpore ridges. Aperture a broad arch at the umbilical edge of the protruding final chamber, bordered by a thickening rim. |
