Hab. Hardwick Bay ; Spencer’s Gulf. 
It has been also found at Oyster Bay, on the east coast of Tas- 
mania. 
This fine species, which has been described by Messrs. Crosse and 
Fischer as a Periploma, to which genus, on account of the inequality 
of its valves, it bears some resemblance, must nevertheless, from its 
gaping and beaked posterior extremity, be placed in the genus 
Anatina of Lamarck.
