1 The genus, Mussa, as here restricted, includes both Mussa and Symphyllia of 

 Milne-Edwards and Haime, — different specimens of the same species sometimes dif- 

 fering in the same way, and to the same extent, as do these two so-called genera. The 

 only difference given, is dependant upon the mode of growth. 



2 It is probable that this, and some of those following it, are only varieties of one 

 species. 



3 The name OrbiceUa is now restricted to the genus of which 0. annularis and 

 0. cavernosa are types. This group is equivalent to Heliastrcea of Edwards and 

 Haime, of more recent date. 



4 The genus, Astrcea, is here restricted to the group of which A. rotulosa is the 

 type. This was the original type named by Lamarck, in 1801, when the genus As- 

 trcea was first established. The genus, thus limited, is equivalent to Favia of Oken, 

 1815. 



6 The genus, Undaria, is equivalent to Pachyseris Edw. and Haime, of later date. 



6 Ocenopsammia is recombined with Dendrophyllia, because in certain species 

 part of the corallets have the structure of the former genus, and others that of the 

 latter, even in the same specimen. The only distinction made is that the former 

 genus has a smaller number of lamella?, — a character that is by itself seldom of gen- 

 eric value. 



7 The genus, Antipathes, as here adopted, includes Cirrhipathes, AracTinopathes, 

 and Rhipidopathes of Edwards and Haime. Those divisions were based only upon 

 the modes of growth and branching, which are quite insufficient for establishing gen- 

 era among Polyps.
