inner and the middle whorls show irregularly-spaced constrictions, and here parabolic nodes are associated on the ribs. Suture lines cannot be seen. Remarks : The specimen shows coiling and ribbing characteristic for Rugiferites . The extremely high number of the ribs indicates a new species, however the single available specimen is insuffi­cient to designate one. The nearest form is R. polypleurus (BUCKMAN), which is the most densely ribbed species hitherto described, but the here figured form shows more numerous ribs, furcation point in lower position and constrictions and parabolic nodes enduring up to the penultimate whorl. R. polypleurus, as well as all known Rugiferites , is known only from the Middle Bathonian, almost exclusively from the lower part of the Subcontractus Zone. Its occurrence in this fauna is a good argument for identifying the Middle Bathonian. The single figured Rugiferites from Sicily is that of WENDT (1963, pp. 69, 137, pi. 20, figs 5.a-b) from Erice. This ammonite, however, seems to belong to the genus Bullatimorphites . More significantly, WENDT (1965, p. 290) included in an Aalenian-Callovian condensed faunal list " Tulites (Rugiferites ) aff. polypleurus (Buckman)", which is a good coincidence.
