eastern fauna than it is at present, there was a fauna in the eastern 

 area during some part of the Tertiary Period with a stronger resem- 

 blance to that of the present Caribean seas than now exists. Thus 

 these various geologico-geographical groups bear a somewhat similar 

 sort of affinity to one another, that we find displayed between certain 

 recent and fossil species of animals. 



"When taken as a whole, the resemblace of the Caribean Miocene 

 fauna to that of Bordeaux, Dax, and Malta is striking, and it is 

 closer than its likeness to the American Miocene *. The present 

 molluscan fauna of the West Indies is not altogether devoid of affi- 

 nities to that of the Mediterranean, and even to that of the Red Sea. 

 Several of the species are, if not identical, at least so near, that they 

 are known by the same names. Hence arises some of the confusion 

 with respect to localities that we occasionally find in conchological 

 books ; the same species being attributed in one to the Mediterranean 

 or to the Red Sea, in another to the West Indies. 



The series of moUusca now described, with those previously de- 

 scribed by Mr. Sowerby, and the corals published by Dr. Duncan, 

 will furnish a basis for future investigations into the geology of the 

 Tertiary formations of the West Indies and Tropical America, and we 

 may expect conclusions of no small interest therefrom,

* By this I mean that there is such a number of types common to the Mio- 

 cene of Bordeaux, &c., that they resemble deposits formed within the same great 

 zoological province. It is in this respect that the resemblance is less close with 

 the American Miocene.
