' 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. 
> It is probable that this, and some of those following it, are only varieties of one 
species. 
3’ The name Orbicella is now restricted to the genus of which 0. annularis and 
O. cavernosa are types. This group is equivalent to Heliastrwa of Edwards and 
Haime, of more recent date. 
* The genus, Astrea, 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. 
tr@a was first established. The genus, thus limited, is equivalent to Aawvia of Oken, 
1815. 
5 The genus, Undaria, is equivalent to Pachyseris Edw. and Haime, of later date. 
5 Cenopsammia 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 lamellz,—a character that is by itself seldom of gen- 
eric value. 
7 The genus, Antipathes, as here adopted, includes Cirrhipathes, Arachnopathes, 
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.
