​​

• The spire is flattened or of moderate height, with 3½ to 3¾ whorls and ornamentation ranging from clear spiral ridges, to interrupted spiral lines, or no ornamentation at all. 

• The spire is sometimes slightly tilted related to the plane of coiling.

• Whorl sutures can be red-brown and juveniles are often red-purple in colour.

• This species has not been found in the Pacific Ocean and is likely restricted to the Atlantic Ocean.

• Eye type a, operculum type c, radula type I.
