Description and discussion A small, slightly curved part of the phragmocone is referred to Forstersspecies. The whorl section is nearly circular on the earliest part preserved. Up to adiameter of 5,5 mm ornament consists of strongly prorsiradiate ribs, separatedby interspaces of similar width. Rib density is about four per whorl height. Theribs weaken markedly on, and pass straight across the dorsum. Tuber-culation commences at a diameter of 5,5 mm; at first only ventral tubercles arepresent, but
