Description

This is a shell rather variable in its colouring pattern but also in the number and in the solidity of the concentric ribs adorning the valves surface. The several colouring pattern varieties such as: lilacina (B.D.D., 1893), zigzag (B.D.D., 1893), luteola, fusca, immaculata, triradiata Deshayes, and other ones, as those concerning the sculpture: raricostata (Jeffreys, 1864), rudis (B.D.D., 1893) and other ones, have no taxonomic value. In the young shells, which have not yet the solid radial ribs, the several fine concentric striae can be pointed out all over the surface. It is the same for the adults : the several fine concentric striae can be pointed out among the radial ribs which have the upper margin quite notched. On the contrary the outline, subtriangular in form, does not change very much during the different growth stages. The average measures are abt. 15 mm in length.
