Volutomitridae: Volutomitra obscura (Hutton, 1873) (‘magpie volute-mitre’)

Synonym(s): obscura Hutton, 1873 pica Reeve, 1845.
Typical shell-length 20 mm. Shell surface bears delicate pale marbling or wave-like patterning on the purplish-black background, but this is often worn away in beached specimens, leaving a pattern of large white blotches on brown. Lives subtidally amongst rocks and seaweed. Native. Endemic to southeastern Australia (TAS, VIC and SA). In Tasmanian waters, this is a widespread species; commoner in the N, and often beached.
