», but we think that this statement overemphasizes the same HOWARTH’ s figure (7b), which like our specimen really shows the weak sulci jointed with a strong and raised keel, which also shows a narrow and gently bisulcate venter in the fragmocone and a narrow and flattened venter in the body chamber. HOWARTH has not provided a draw or description of the suture line of SPATH’ s

The Italian specimens figured by MENEGHINI (1870, pl. 11, fig. 7), ZANZUCCHI (1963, pl. 18, figs. 1-6) and PINNA (1969, pl. 1, fig. 16) have an uncertain taxonomy, as well as the little and badly preserved small sized fragment of the GEMELLARO’ s collection, recently revisioned by MACCHIONI (2002b, p. 147). However, they have not stratigraphical recording. We also doubt whether to ascribe the specimens figured by WIEDENMAYER (1980, pl. 32, figs. 3-5) to
