Description
The shell of an Idaho forestsnail is up to 24 mm in diameter and 15 mm in height, and is heliciform with up to 5 3/4 whorls. The shell is covered with a light brown periostracum that wears away over time, and incrementally has lighter striations and axial riblets. The aperture is oval, white, and slightly thickened near the base with a callus.[2][3]
It can be found in northern Idaho, western Montana, eastern Washington, and southeastern British Columbia.[4]
