synonyms, as before, numbers seventeen species.* Since then our list 

 has increased to number twenty-six or twenty- seven, and whole genera 

 are still unrepresented. From the above I have purposely excluded any 

 mention of the Lucernariadae, not seeing how this family can be placed 

 among the Actinozoa; and in this view I believe Professor J. Reay 

 Greene coincides, although he has placed the three species which fre- 

 quent our coast in his list. As an appendix, I shall briefly allude to 

 them, as they are still, though erroneously, believed to have affinities 

 with the Actinia. In nomenclature I shall adopt that of my friend, 

 Mr. Gosse, so far as his synopsis of the ActinidaG goes ; to the end of 

 the Sagartia I have adopted his " Actinologia Britannica." 



Before entering on a detailed list of the species, I think it better to 

 allude briefly to the various marine provinces into which I think it most 

 convenient and desirable to divide the sea-coast of Ireland. A division 

 of this nature must be more or less arbitrary ; but I trust the one that I 

 now propose will be found sufficiently correct for general adoption by 

 our Irish zoologists.
