Spelling
The specific name was originally introduced in the binomen Buccinum grana, translated in French as "buccin graine". This has been emended to granum by Kiener (1834: 22) and most subsequent authors, presumably considering that the correct Latin word for "graine" ("seed") is granum. Therefore, the spelling granum must be conserved in application of ICZN art. 33.2.3.1. "when an unjustified emendation is in prevailing usage and is attributed to the original author and date it is deemed to be a justified emendation".[2]
Description
The shell size varies between 10 mm and 14 mm
The small shell is ovate, pretty thick, reddish, smooth and shining. It is surrounded with interrupted, small, brown lines, more approximate towards the middle of the lowest whorl, and of a deeper color at the base. The spire is elongated, pointed. It is composed of seven slightly convex whorls, surrounded at their upper part by a white band, sprinkled with distant, brown points or spots. The aperture is white. The internal edge of the outer lip is crenulated, the external part forming a smooth, thick callus, of a dull white, which is continued upon the base of the shell even to the columella, which is arcuated and folded at its base.[3]
Distribution
This species occurs in the Mediterranean Sea and in the Atlantic Ocean off Senegal.
