Habitat: Java (DUMERIL). Coasts of Australia, Tasmania, 

 Lord Howe Island, New Zealand. 



Note. DUMERIL says that there is a specimen of this species 

 in the Paris Museum, collected by FONTANIER, from Java. 

 As this australian species has never been found again in the 

 indo-australian Archipelago, we doubt the correctness of the 

 locality, where FoNTANIER is said to have found his specimen.
