84 MANUAL OF THE MOLLUSCA. 
XVII. CARIBBEAN PROVINCE. 
The Gulf of Mexico, the West Indian Islands, and the eastern 
coast of South America, as far as Rio, form the fourth great 
tropical region of marine life. The number of shells is esti- 
mated by Prof. C. B. Adams at not less than 1500 species. Of 
these 500 are described by M. D’Orbigny in Ramon de la Sagra’s 
History of Cuba, and a small number of the Brazilian species 
in the same author’s Travels in South America. A list of the 
Barbadoes shells has been given by Sir R. 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.
