Amalda edithae

From the dorsal view, the body whorl makes up slightly more than half of the shell’s total length and is finely striated both longitudinally and spirally.

The uppermost basal groove begins at the columellar callosity, just below the body whorl’s center, ending in a subtle projection of the outer lip.

This groove is succeeded by a well-defined ridge that curves slightly concavely at the lip due to the backward sweep of the notch.

The aperture is narrow and lanceolate, with an acute outer lip that has a well-defined sinus at its juncture with the body whorl.

The enamel band is similarly colored with dashes that obliquely cross the suture, reverse direction, and continue around the spire.
