Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| A. R. Loeblich and H. Tappan 1957 | Test free, lenticular, robust, periphery acute; chambers biserially arranged and spiralling, as in Cassidulina, each chamber extending to the umbilicus on one side with only a small triangular portion extending over onto the opposite side; sutures not visible from the surface, obscured by the coarse surface ornamentation; wall calcareous, finely perforate, granular in structure, ornamented by a honeycomblike secondary growth, with relatively wide hexagonal open areas separated by narrow but much elevated "partitions"; aperture elongate, a slightly curved slit bordered by a very narrow lip, and extending upward from the base of the final chamber, near to and paralleling the anterior margin of the chamber, and opening toward the side opposite that on which the final chamber lies, each successive aperture appearing on alternate sides of the test, the region immediately surrounding the aperture relatively smooth. |
