The Coast Range Shoulderband is one of the most common native snails in the Bay Area. Like other shoulderbands, it has a single dark line running up the middle of the spiral of its shell, but it can be distinguished from the other shoulderband in SF (H. arrosa) by the tiny, elongate, regular ridges on the shell, somewhat resembling lines of Morse code. Its habitat preferences are varied, but open woodland, particularly near creeks, seem like a favorite.
