Typical shell-length 25 mm. Dark stripes on the body-whorl tend to be continuous, narrower than the paler interstices, and at an oblique angle. However, some forms are difficult to distinguish from A. brevis. Lives intertidally amongst rocks and seaweed, especially on moderately exposed shores. Native. Endemic to southeastern and southwestern Australia (QLD, NSW, TAS, VIC, SA and WA). In Tasmanian waters, this is a widespread species in N and NE Tasmania; rare or absent further S.
