Raphitoma densa (Monterosato, 1884)
Canarias, Mediterranean.
Predator in the infralittoral and the circalittoral.
 
« Teleoconch of 7-9 convex whorls, slender and stout, suture incised, sculpture robust. Densely disseminated microgranules in the surface. Axial sculpture of 16-29 orthocline, equidistant ribs, and interspaces slightly narrower than the ribs. Spiral sculpture of 6-9 cordlets above the aperture. Cancellation rectangular, with strong and sligthly acute tubercles at the intersection of axials and spirals. Subsutural ramp narrow, with small tubercles in correspondence with the axial ribs tip and one or two small spiral cordlets. Columella simple, slightly sinuous anteriorly, gently angled posteriorly. Siphonal channel short. Outer lip with 10-14 strong inner lyrate denticles, the most posterior is shorter. Siphonal fasciole with 6-10 strong nodulose cord. Colour uniformly orange brown in the background (from ligth to dark), with large ashy blotches, as wide as 1-3 axial ribs. Suprasutural cordlet (rarely two) at least on the last whorl. Comma-shaped ashy spots on the subsutural ramp. Enterely white specimens are known. » – Giannuzzi-Savelli, Pusateri & Bartolini: “A revision of the Mediterranean Raphitomidae 7”, Biodiversity Journal 2018, 9 (4), p.433.
