To these must be added two species, Ehizoxenia alba and Sympodiimi margaritaceum^ 

 described by James Grieg from the coasts of Norway, both of them being undoubtedly

The following species have been too imperfectly described to enter into any modern 

 system : — Anthelia rubra of delle Chiaje, Anthelia olivi and Anthelia domuncula of 

 de BlainviUe. 



Genus Sympodium (Ehrenberg). 



Some doubt has been thrown upon the stability of this genus by the recent investi- 

 gations of von Koch (18) upon Sympodium coralloides, who has shown that this form 

 is a true Alcyonid adapted to live on a Gorgonia stem, and proposes that its name should 

 be changed to Alcyonium coralloides. It is possible that, when they are properly 

 examined histologically, the other species attributed to Symjiodium may turn out to be 

 after all true Alcyonians with a modified habit. For the present, however, it may be 

 allowed to stand provisionally, and the reader may be referred to the excellent account of 

 the genus in the ' Challenger ' volume for the species that have been hitherto described.
