Amalda mamillata, common name the mammillate ancilla, is a species of sea snail, a marine gastropod mollusc in the family Ancillariidae.[1]

Description

The length of the shell varies between 30 mm and 60 mm.

(Original description in Latin) The shell is elongated-ovate. It is orange-tawny in color. The body whorl is banded more intensely at the top and base. The spire is very mammillate, grooved, as if lathe-turned, with a pointed apex, and is prominently covered with a rough callus at the front and on the right side. The lower part of the outer lip is toothed, and the columella is thickened with a white callus.[2]
