Of NEW SOUTH WALES. 27 



The genus Alexia appears to be confined to Europe, Great 

 Britain, and some of the West Indian Islands. This is, I believe, 

 the first recorded species found in the Southern Hemisphere. 

 Mr. Angas, in his list of the Molluscan Fauna of the Province 

 of South Australia, given in the Proceedings of the Zoological 

 Society of London, 1865, does not mention any of the Family 

 Auriculacea. I have received, Marinula patula, Lowe — Marinula 

 xanthostoma — H. and A. Adams, from South Australia. It is 

 also found in Port Jackson, and on the coast of Tasmania.
