To judge of the marine Mollusca of the Azores from the few species 

 received from thence, they appear to be generally identical with those of the 

 Mediterranean, except a very few species not identified, and several littoral 

 species, such as Littorina striata, Mitrafusca, Miira zehrina, Pedipes, which 

 are not European, but common to Madeira and the Canary Islands.
