The shell surface is chalky white, crossed by horizontal purple to black streaks on the seven rounded axial ribs, that are twisted and swollen at the base of the body whorl.
The ovate aperture has a small anal canal that point slightly backwards.
The outer lip is crenulate, but has a smooth inner surface.
The siphonal canal is moderately long and, typical for this genus, fused above, almost sealed below and pointing to the left at its base.
[2][3] This species is distributed in the Pacific Ocean along the Galápagos Islands.
