[3] This snail has a shiny, rounded, grayish to brownish white shell up to 1.9 centimeters wide.
The body is dark gray to black with copper flecks along the skirt and tail tip.
[3] The snail lives on rocky mountain slopes, taking shelter in talus and rockslides.
During the dry conditions common in its habitat, the snail seals its shell aperture to solid rock to avoid desiccation.
It is associated with local plant species such as saguaro cactus (Carnegiea gigantea), yellow paloverde (Parkinsonia microphylla), brittlebush (Encelia farinosa), foxtail brome (Bromus madritensis), Natal grass (Melinis repens), creosote bush (Larrea tridentata), and Coulter's lupine (Lupinus sparsiflorus).
