| R. V. Kesling 1962 | Rhombiferan cystoids with the theca elongate and consisting of five 00, five RR, five LL, at least four ILL (presumably five), and presumably four BB. Rhombs developed only between ILL and between LL. RR reduced to small plates, alternating with 00 and with them forming a slightly elevated ring around the peristome. Brachioles erect, attached to facets on the RR. |
