Description
A medium-sized marine gastropod, commonly known as Fournier's Hornmouth or Fournier's Murex. The shell is robust, with a dark reddish-brown to purplish-brown exterior and a prominent, somewhat angular shape due to strong, frilly or spiny axial varices. The aperture is ovate, featuring a lighter, almost white rim and a deep reddish-brown interior. It is typically found in rocky intertidal and subtidal zones.
