The genus is named after Acteon, a character in Greek mythology.

Description

The shell is convoluted, ovate, cylindrical, generally transversely striated. The aperture is oblong, entire, somewhat effuse at its base. It shows one or more folds upon the columella. The outer lip is thin, sharp, never having a varix.

The species of this genus are all marine, and convolute. They are almost always transversely striated. They are generally oval and cylindrical. The spire is more or less projecting and obtuse. The aperture is elongated, often narrowed at its posterior part, widened and somewhat effuse at its base. The folds of the columella vary from one to three. They are generally thick and obtuse.[1]

In the genus Acteon, the individual teeth of the radula are very small. There are many teeth in each row.
