Description

The length of the shell varies between 5 mm and 25 mm. The hemispherical shell is smooth, depressed, convex above and flattened beneath. The blunt spire is formed of four indistinct whorls, entirely smooth. The

aperture In optics, the aperture of an optical system (including a system consisting of a single lens) is the hole or opening that primarily limits light propagated through the system. More specifically, the entrance pupil as the front side image o ...

. The coloring is slightly variable, it is generally of a yellowish or reddish white, with brown lines, and two decurrent, interrupted, or articulated bands, one of which surrounds the suture, and the other only borders the circumference. The epidermis is thick and brown.Kiener (1840).
