B. regia, Gosse. 



On stone dredged in five fathoms, Landtivet (?) Bay, coast of

Order ALCYONAEIA, ^lilne-Edwards. Fam. Alcyoniadae. 



]. Alcyoxium, Linnaeus.

2. Sarcodictyox, Forbes.

 [Gosse): rid. Ann. Nat. Hist. ser. 3. vol. ii. (1858), p. 276. 

 [On stones from deep water, ofi^ the coast of Antrim.] 



Fam. Pennataliadas. 



Penxatula, Linnaeus. 



P. phosphorea, Linn. 



This is included among Devon species, on the authority of 

 Turton and Kingston (' Nat. Hist, of Torquay, Dawlish, and 

 Teignmouth^). We can hardly suppose that they were mistaken 

 about so marked a form. But the Pennatula must be of extreme 

 rarity on the western coast, as we have, I believe, no other record 

 of its occurrence. 



It is abundant along the coast of Norway, as well as on our 

 own northern shores, and is included also in the Mediterranean 

 ' Littoral-Fauna' of Sars ; but this author states that the southern 

 form is much inferior in size to the northern. 



Fam. Gtorgoniadae. 



Gorgonia, Linnaeus. 



G. verrucosa, Linn. 



Common along the coasts of Devon and Cornwall, in about 

 30-40 fathoms' depth. 



Sars informs us that in the Grotto of Nisita, where at middav 

 there is only twilight, the Gorgonia occurs frequently, attached 

 to the precipitous walls of rock, at a depth of from half a fathom 

 to a fathom below the surface of the sea. In this situation it 

 grows to the height of one foot. 



G. verrucosa is found elsewhere in the Mediterranean at a depth
