ANTHOZOA HYDEOIDA. 



Family CORYNID^E. 



In June 1843, I received from Joshua Alder, Esq., of Newcastle, 

 the figure and description of a Zoophyte which may, perhaps, be re- 

 ferable to the genus Hydractinia, but is evidently distinct from any 

 described species, and indeed from any polype known to me. The

 portion when contracted. 

 Is Tubularia ever with- 

 out a tube in any stage 

 of its existence ? I know 

 Coryne squamata : it is 

 not that." 



Sars has lately characterised the genus Hydractinia under the 

 name of Podocoryna. Fauna littoralis Norvegise, i., p. 4. His P. 

 carnea is evidently the same as the Hydractinia rosea of Van 

 Beneden. 



Family TUBULARIAD^E. 



Professor Reid of St. Andrews, has communicated (Nov. 1845) an 

 account of a zoophyte nearly related to CorymorpJia. (Fig. 79, 6.) 

 " It was about an inch in length, and of a pale fawn colour through-
