DESCRIPTION

Shell is large-sized, massive, highly conical, whorls are flat, stepped, separated by thin suture lines, increasing in width and height from apex to aperture, there are 11 or 12 convex, slightly opisthocline axial ribs on each whorl of the early teleoconch, decreasing in numbers but increasing in width towards body whorl, body whorl is relatively small, rounded, quadrangular, with a short siphonal channel.

REMARKS.

Cerithium vicetinum Bayan, 1870 represents a synonym based on juvenile specimens of C. giganteum and a mistake due to ontogenetic changes in sculpture. Campanile lachesis ( Bayan, 1870) has similar height and whorl shape to C. giganteum more slender shell with many whorls with strong adapical nodes, which may be elongated to short spines. Campanile paronae Boussac, 1911 , from the late Eocene of France, differs in having flat spire whorls with disordered thick and rounded tubercules increasing in size towards the body whorl ( Boussac 1911: 283, 284, pl. 17, figs 59, 63, 64 [Turin Basin]).
