Amalda hilgendorfi is a species of sea snail, a marine gastropod mollusc in the family Ancillariidae, the olives.
Description
This species attains a size of 50 mm, its diameter 18 mm.The shell is fusiform-turreted, very faintly grooved in spirals. It is violet-white in color, with a pale orange callus covering the upper whorls and the sutural area of the penultimate and body whorls. Near the base, there is a more violet-colored band bordered above by a spiral groove, followed by a slightly swollen, pale orange callus.
The aperture is rather narrowly elliptical, approximately half the total length of the shell. It is white, with a blunt outer edge that is very slightly arched and thickened above. Near the base, it shows a small denticle, while the basal margin is broadly notched. The columellar margin is slightly sinuous and is sculpted outwardly with several obliquely aligned, somewhat indistinct folds. A thin white callus extends onto the final and penultimate whorls.
