species being attached,; alterations in the generic names and specific determinations by 
the authors of the Monograph, subsequently to its completion, will be noticed, and also 
whatever fresh information may be requisite about previously described species. 
It is hoped that after the description of all the new species has been finished there 
will be an opportunity for noticing the geographical distribution of Corals, and the pecu- 
harities of the paleontological evidence offered by them. : 
Nore.—In writing this Supplement, or, as I have termed it, ‘‘ Second Series,’ [am most anxious to 
acknowledge that the foundation of all my knowledge upon the anatomy, physiology, and classification of 
the Zoantharia was derived from the writings of MM. Milne-Edwards and Jules Haime. It will be found 
that the greater part of the following Introduction is taken, if not in exact words, still in ideas, from those 
writings ; and if any paleontologist or naturalist should think that I have neglected other works, it may, 
perhaps, be an excuse, that it is right, in following such distinguished men as those who wrote the “ First 
Series,’ to carry on their train of thought, and to choose the results of their labours in preference to 
those of others in compiling the “ Second Series.”
