I found this empty shell at Ricketts Glen State Park near the same fallen log that I found the Anguispira alternata. It measures 18.1mm in width. The books list this as 19mm to 25mm but I figure that's close enough. One interesting thing is that I can see what looks like a pupa/chrysalis inside the shell.
