thoa Couchi, Johnston; and P. sulcata, Gosse. Of these thirty-one 
species, twenty-five (that is to say, about five sixths) inhabit the seas 
of Great Britain, and have been described in the ‘ Actinologia Bri- 
tannica’ of Mr. Gosse. The six species which are wanting in Eng- 
land are Cerianthus membranaceus, Edwardsia Harassu, EH. tu- 
mida, Sagartia ignea, S. erythrochila, and Bunodes biscayensis. The 
Cerianthus belongs to the Mediterranean fauna, as, perhaps, does also 
Sagartia erythrochila. 
The twenty-five species of our coasts which inhabit the English 
seas only furnish three species which extend as far as the Mediter- 
ranean; these are Anemonia sulcata, Actinia equina, and Adamsia 
palliata. 
Our French actinological fauna nevertheless differs from that of 
the coasts of Great Britain by the absence of several genera which 
have an eminently boreal character, and which are found chiefly in 
the Shetlands and north of Scotland; such are the genera Phellia, 
Gregoria, Bolocera, Hormathia, Stomphia, Ilyanthus, Capnea, Aure- 
liania, and Zoanthus. One can hardly cite three species of Actiniz 
in the Mediterranean which are wanting on our oceanic coasts. We 
may conclude from this that, if our ocean shores possess many 
Actinie and few Gorgoniz and Corals*, the Mediterranean presents 
the opposite condition. 
The bathymetric distribution of the Actinic is very simple; they 
nearly all live in shallow water; they are only found in the littoral 
zones, and that of the Laminarie (0-28 metres) and Nullipores 
(28-72 metres). Beyond this point occur the greater part of the 
Corals which characterize the following zone, that of Brachiopods 
and Corals (72-184 metres). 
In the littoral zone Actinia equina, Anemonia sulcata, Sagartia 
ignea, S. erythrochila, Bunodes verrucosus, Palythoa sulcata, &c. 
chiefly live. 
The Laminarian zone is principally inhabited by the non-adherent 
Actiniw, as well as by Metridium dianthus, Sagartia sphyrodeta, 8. 
pellucida, &c. 
In the zone of Nullipores, or of the great Buccina, we dredge up 
on shells Sagartia effecta, S. viduata, Adamsia pallata, Chitonactis 
coronata, and Palythoa Couchi. 
All zoologists who have attended to the specific distinction of the 
Actiniz have sought to establish the number of cycles and the 
number of tentacles in each cycle. The number of cycles is not 
absolute; it is not uncommon to find one cycle more or less in 
adult specimens of the same species: thus Tealia felina has five 
* The Corals of our oceanic shores are Caryophyllia Smithi, Dendro- 
phyllia cornigera, Desmophyllum crista-galli, and Paracyathus striatus. 
The Gorgonize are Gorgonia verrucosa, Pterogorgia rhizomorpha, and 
Muricea placomus.
