The shell has a spiral structure, with a commonly off-white colouration above the periphery on the upper half of the whorl, and dark brown below it. It has a narrow brown band above the suture with a moderately developed spiral sculpture in comparison with other species of the genus Carinodrillia.[2] The length of the shell varies between 15 mm and 26 mm.
