}}Raphitoma linearis is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae.[1] DescriptionThe shell is fusiform and turriculate. It has an elevated and acute spire. The twelve whorls are convex and longitudinally costated (twelve ribs on the body whorl). They are transversally sharply striated with 6-7 elevated lines, which run along the volutions. They are rather broader over the ribs and very sharp between them The outer lip is thickened on the outside with an obtuse varix or rib, but smooth within. The siphonal canal is short, rather broad and slightly inflected.[2] DistributionThis marine species occurs in European waters from Norway to the Azores; in the Mediterranean Sea.
