Molluscs of Tasmania

Trochidae – Monodontinae: Austrocochlea porcata (A. Adams, 1853) (‘striped top-shell’)

Synonym(s): porcata A. Adams, 1853 obtusus of authors (non Dillwyn) zebra Menke, 1829 taeniatus Quoy & Gaimard, 1834 constrictus Quoy & Gaimard, 1834 (in part) extenuatus Fischer, 1876 multicarinatus Fishe, 1876.

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.
