continent, into his single Occidental province. The South- 

 African province is not brought out by Mr. Dana so pro- 

 minently, as I have found necessary. Mr. Dana joins the East 

 Indian Archipelago and Australia into his single Oriental 

 province, and makes New Zealand, as a sub-province, ap- 

 parently as distinct from Australia, as Australia is from the 

 East Indian Archipelago : whereas I find that the Cirripedes 

 of New Zealand clearly belong to Australia ; and that the 

 Australian Cirripedes, especially if the temperate shores be 

 alone considered, are as distinct from those of the East 

 Indian Archipelago, as from those of any other quarter 

 of the whole world. I believe that the provinces deduced 

 from the distribution of Cirripedes, accord better with the 

 Molluscan provinces, than with those given by Mr. Dana 

 for the rest of the great class of Crustaceans. 



In the following tables, an asterisk means that the 

 species is not found in any other distinct region of the 

 globe. When found in one of the five provinces, a cor- 

 responding number, within brackets, is appended, to show 

 in which province or sub-province it has been found.
