Taxonomy & Nomenclature

Synonym/s: Placostylus bivaricosus cuniculinsulae Cox, 1872; Bulimus cuniculinsulae Cox, 1872

 

Considered a junior synonym of P. bivaricosus by (MolluscaBase, 2021a,b).

Extinct or invalid (synonym)

Last record: before 1901 (Department of the Environment, 2014)

A targeted survey of Blackburn Island in 1999 did not find the species (Ponder & Chapman, 1999)

 

Distribution

Blackburn (=Rabbit) Island*, in the lagoon of Lord Howe Island, New South Wales, Australia

 

* "Blackburn Island was named after David Blackburn, sailing master of the Supply. Its named changed to Goat Island, then Rabbit Island and back to Blackburn Island officially in 1973. The ‘Rabbit Island’ nickname probably has its origins from the unattended burrows of the Wedge-tailed shearwaters that are very similar to that of a rabbit."
