Description

The length of the shell varies between 45 mm and 60 mm. The white, elongate, fusiform shell is transversely finely ridged throughout, the numerous ridges being articulated with minute brown dots. The spire is acuminate. The shell contains fourteen, flattish whorls. These are on top angulate and excavated below the suture. The

body whorl The body whorl is part of the morphology of the shell in those gastropod mollusks that possess a coiled shell. The term is also sometimes used in a similar way to describe the shell of a cephalopod mollusk. In gastropods In gastropods, the b ...
