REEF CORALS. 



The corals constituting the Florida Reefs, or growing in the shoaler 

 waters of that region, belong to the "West Indian Fauna, without 

 exception. They have been made a special object of study by Professor 

 Agassiz for many years, and this part of the catalogue was to have 

 been written by him. But as the multiplicity of other labors has thus 

 far prevented him from putting this project in execution, and as a long 

 absence from the Musemn will still further protract the delay, it has 

 appeared preferable to add this list, with remarks from notes made by 

 me in the field and in the Museum, so as to have as complete a view of 

 the coral fauna of Florida as possible. 



Professor Agassiz's future work will bear chiefly on the structure of the 

 23olyp as well as of the hard parts, and on the geological part taken by 

 the diflterent corals in the formation of the reefs aud of the peninsula of 

 Florida.
