Olivella barbenthos

Shell is medium-sized for the genus (6.2 - 8.6 mm.) with 6-7 whorls, stout, oval and short spired. Suture narrow and deep. A part of the ventral side of the shell is covered with thickened callus. Protoconch small. The columella has two series of plicae, an upper and a lower one. The upper series consists of 3-5 plicae, the lower of 4-5. The ground colour is white. The shell has an interrupted band around the middle of the body whorl, which is sometimes vague on lighter coloured specimens. The body whorl is covered with light to dark brown longitudinal waves. Darker specimens have a purple band around the body whorl just below the suture. This band is white on lighter coloured shells, which are more frequent. A light to dark brown fasciolar band is present.
