This typical Lissoceras has a narrow umbilicus, high and arched umbilical wall, rounded umbilical margin.i slightly convex flanks and somewhat flattened venter. The whorls are completely smooth. Entire suture line cannot be seen, but portions of the characteristic haploceratid suture are visible. Remarks: L. ferrifex, the type of which came from the condensed Bathonian of Swinitza, ia fairly common in Mediterranean Bathonian faunas. The species was described from Sicily by WENDT (1963, p. 20), however that form is probably a specimen of L. oolithicum . on the basis of its wide umbilicus and different suture line (see GALÁCZ, 1980, p. 60).

Cadomites (Polyplectites) cornutus KOPIK, 1974 — SANDOVAL, p. 299, pi. 23, fig. 7; text-fig. 108-F (only) Description : A small, wholly septate, well-preserved specimen. The dimensions at 31 mm maximal preserved diameter are 12 (39%); 18 (58%); 10.5 (34%). The specimen is probably a nearly entire phragmocone, as indicated by the beginning of a slight excentricity shown in the umbilical seam of the last preserved part. The umbilicus is moderately narrow, deep, with rounded umbilical wall. The whorl-sides are convex, the venter is broadly arched. The sculpture consists of projected and forwardly arched primary ribs ending in small, sharp tubercles somewhat below the middle of the whorl-side. The number of primaries is 31 on the last preserved whorl. The density of the primary ribs is variable, there are segments with denser and others with slightly sparser costae. The tubercles are furcation points for dense, sharp secondary ribs. The last whorl bears 110 secondary ribs, i.e. the secondary/primary rib ratio is 3.5. Suture line cannot be seen because of the presence of recrystallized shell throughout the whorls. Remarks : C. (P.) cornutus, described from the Polish Lower Bathonian, Is probably a species of wider geographic distribution. Recently it was recorded from Spain (SANDOVAL 1983). From the Betic Cordilleras SANDOVAL figured a large Polyplectites from the Upper Bajocian (loc. cit. p. 20, fig. 4), which is regarded here as non conspecific. A similar form is C. (P.) zlatarskii. also of Lower Bathonian, but this species is smaller, showing the end of the phragmocone at ca. 25 mm, and has a denser ribbing (see GALÁCZ 1980, p. 76). The subgenus Polyplectites is well-represented in Sicily (see WENDT 1963). The form figured by WENDT (loc. cit., p. 132, pi. 21, figs 2.a-b) is similar but smaller, with a contracted body chamber which begins at ca. 21 mm diameter. C. (P.) cornutus seems to be restricted to the Lower Bathonian, just as many other smallsized Cadomites microconchs in the Mediterranean region.
