REMARKS. — The validity of Pictodentalium festivum was established by Scarabino (1995: 269) after examination of the type material and other specimens of both species and I do not agree with the synonymy proposed by Lamprell & Healy (1998). Pictodentalium festivum has more ribs (17-19), is slightly more pointed in section, and all the material examined displayed secondary ribs. The ribs of P. formosum are wide and rounded in section, fewer in number (13-17) and there are no secondary ribs. Also the colour pattern is different, P. formosum being basically dark purple with rose and green patches, while P. festivum is pale purple, rose and cream.
