Description
The shell has an equilateral-triangle profile, being approximately as tall as it is wide. The whorls are slightly inflated and are sculpted with strongly beaded spiral threads and a row of splayed hollow spines along the shoulder. A smaller second row of spines is situated below the shoulder on the last whorl. The base color of the shell is lavender to reddish purple with golden maculations outlined in a darker purple. The base has strong spiral threads which are weakly beaded and is paler in color than the body, with scattered darker and lighter beads along the threads. The siphonal canal is closed and is ivory white near the aperture with a golden yellow to orange edge adjacent to the base. The aperture is white and nacreous.
