1908-9.] THE GEOLOGICAL CONNEXIONS OF THE CARIBEAN' REGION. —~ 391 
There are several other species of Caribean miocene fossils upon 
which I should like to say a word or two, but I feel that I must bring 
my paper to anend. The proper place for further remarks would, no 
doubt, be a monographic review of the Caribean fossils. It is, however, 
unlikely that any such undertaking would ever fall to me. 
It is, I think, pretty clearly made out that there was in tertiary times 
a land connexion between the Caribean and North Africa and a sea 
connexion between the Caribean Sea and the Pacific. The land con- 
nexion and the sea connexion probably existed in cretaceous times, and 
were in progress of slow alteration during later cretaceous time, and 
came to an end during the tertiary period, probably at the termination 
of the miocene, when the final remnant of the Atlantis disappeared and 
the Isthmus of Panama rose above the sea level, and the last gap in the 
Andes was elosed.
