Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| A. F. M. Haque 1956 | Test small, oval, longer than broad, biconvex, nearly bilaterally symmetrical. Periphery sub-acute, broadly rounded, lobate. Dorsal side flat or slightly convex, showing all the chambers. Ventral side completely involute, umbilicate. Chambers distinct, inflated, globose, somewhat overlapping, about 6 in the adult whorl, rather rapidly increasing in size as added; last two chambers occupy more than half of the test. Sutures distinct, depressed, somewhat curved on the dorsal side, radial on the ventral. Surface smooth, shiny. Wall calcareous, very finely perforate, built of radially arranged crystals of calcite. Aperture an elongate slit at the base of the last chamber of the outer whorl extending from the periphery to the umbilicus with a narrow lip. |
