Description
The size of the shell varies between .
This species normally has a sinistral (left-handed) shell, thus the scientific name. (When the shell is held with the spiral end up, the opening is on the left side.) The spire is low and the siphonal canal is long. There is a distinct shoulder where the spire meets the body whorl; knobs of small to moderate size are found at the shoulder. The base color of the shell is variable but is usually pale, and the shell is marked with dark stripes that run down its long axis.
