Cantharidus Callichrous

''Cantharidus'', common name the kelp shells, is a genus of sea snails, marine gastropod molluscs of the family Trochidae, the top shells.Rosenberg, G.; Bouchet, P. (2013). Cantharidus Montfort, 1810. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=204763 on 2014-01-12

Description

The shell has an ovate-conic or pyramidal shape. It is imperforate, smooth or spirally sculptured outside, brilliantly iridescent within. The colors are generally bright and variegated. The aperture is less than half the length of shell, longer than wide, ovate. The columella is usually more or less folded or toothed near the base.Tryon (1889), Manual of Conchology XI, Academy of Natural Sciences, Philadelphia

The central tooth of the radula has a body with broadly expanded supporting wings, a narrowed peduncle or neck, which bears a simple cusp. This peduncle has on each side delicate wings. The lateral teeth number five on each side and have as peculiarity that they increase in size from the inner to the outer one. The inner lateral is slender, narrowed toward the cusp, like the centrals, and (sometimes at any rate) bearing a lamella behind the peduncle. The outer laterals are very broad, with one or several denticles on the cusp. The only character separating ''Cantharidus'' from ''Gibbula'' is the simple cusp of the central tooth, whilst in ''Gibbula'' it is denticulate at the sides.

Distribution

This genus is composed of marine species with a wide distribution, occurring off Australia, New Zealand, the Philippines, French Polynesia, South Korea, Japan, Indonesia, New Caledonia, Oceania, East India, Africa.
