| The adoral zone runs into this pocket and the mouth is located in its lower right-hand corner. |
| In all cases the apical part of the conch is more heavily overgrown than in adoral sections. |
| The coiled shells are mostly nearly complete, but often the body chambers are broken ventrally and adoral parts are missing. |
| These individuals are rare, are less than 15 mm in test diameter, and contain spines very similar to the thin, gracile, lightly ornamented, adoral spines of larger specimens. |
| Therefore, in these early stages, the boundary can be drawn between these aboral plates and those formed adoral to the terminals. |
| In front the peristome bends sharply to the right and extends as far as the right end of the adoral zone. |
