Conus (Chelyconus) mediterraneus (Hwass in Bruguière, 1792)
Conus ventricosus (Gmelin, 1790)
Conus ventricosus (Bronn, 1831) - Pliocene
Conus (Chelyconus) mediterraneus permiocenica (Sacco, 1893)
Hall (1966) was correct to interpret this species as a very polymorphic species comparable to the extant Lautoconus ventricosus . Especially the height of the spire and the convexity of the spire whorls are very variable. Similarly, the outline of the last whorl ranges from slightly ventricose to nearly straight-sided. Like the recent L. ventricosus , the spire of the Miocene C. vindobonensis tends to be more or less gradate in some specimens. Consequently, the high spired, gradate specimens illustrated by Hoernes & Auinger (1879, pl. 6, figs 10–11) as Conus mediterraneus are most probably aberrant specimens of Conilithes vindobonensis . Therefore, Conus mediterraneus var. pupoidemiocenica and permiocenica, which were introduced by Sacco (1893b) as new names for these specimens, are subjective junior synonyms of Conus vindobonensis (4).
