Description

One turbinate freshwater snail shell. The exterior is varying shades of brown. The periostracum on the shell's apex and nodules is worn leaving areas of white. The interior is cream. The shell has five whorls, shallow, well-defined sutures, transverse growth lines, and is covered with large nodules. The shell appears to have large plates that form its construction, hence the common name "Armored rocksnail." The dextral shell has an oval-shaped aperture with lips that are slightly reflected onto the base of the shell.
