Conus argillicola (Eichwald, 1830)
Although Hall (1966) synonymized this species with Conus
vindobonensis Hoernes & Auinger, 1879, the two taxa are not very similar.
Especially the elongate last whorl and the long siphonal canal exclude
conspecificity with Conus s.l. vindobonensis. Moreover, the
spiral cords on the spire whorls of C. s.l. vindobonensis are always
much weaker. Bałuk (1997) treated Conus argillicola as a subjective
junior synonym of Conus pyrula Brocchi, 1814. The Pliocene Lautoconus
pyrula, however, lacks spiral cords, is broader, and has rounded shoulders
and very prominent and broad spiral cords on the base. The illustration of
Eichwald (1852) does not correspond unambiguously to any other Paratethyan and
Mediterranean species and the status of Conus argillicola remains
unclear without observation of type specimens or new material (5).
