MANITAL OF THE MOLLTJSCA. 



Xyil. Cahibbeax Proyin'ce. 



The Gulf of Mexico, the West Indian Islands, and tho eastern. 

 coast of South America, as far as Pdo, form the fourth great 

 troiDical region of marine life. The number of shells is esti- 

 mated by Prof. C. B. Adams at not less than loOO species. Of 

 these 500 are described by M. D'Orbignyin Eamonde la Sagra's 

 History of Cuba, and a small number of the Brazilian si^ecies 

 in the same author's Travels in South America. A list of the 

 Barbadoes shells has been given by Sir E. Schomburgk. 



The coasts of the Antilles, Bermuda, and Brazil, are fringed 

 •with coral reefs, and there are considerable banks of gulf- weed 

 at some distance from the coast of the Antilles.
