The tendency of all these facts can hardly be mistaken, and I 

 think I have said enough to show that my conclusions are based on 

 no mere superficial analogy. I have endeavoured to suggest what 

 seems the most probable explanation ; and I may add that, as it has 

 been shown that it is highly probable that a great part of N'orth 

 Africa was submerged within the Tertiary period*, it may be that a 

 part of the West-Indian Miocene fauna migrated to south Europe 

 and the East by that route. As I have already mentioned, Lucina 

 tigrina occurs fossil in Egypt. It will be unnecessary for me to say 

 more on this point, because it is easier to explain the migration of 

 species on this side of the Atlantic than to account for the mode in 

 which they crossed that ocean. It is not, however, without some
