There are four other species of Sertularella which I have not 

 yet found, although S. gayi certainly occurs. 

 Diphasia attenuata, Hincks. 



Common on zoophytes, and sometimes on seaweed. It is the 

 only species out of seven that I have at present found. Deal, 

 Sandgate, Dover, Folkestone. 

 Sertularia pumila, Linn. 



Very common, especially upon seaweed, whose fronds it often 

 thickly covers. I have not found it upon zoophytes. Sandgate, 

 Bexhill, Heme Bay, Whitstable, St. Leonards, Folkestone. 



Sertularia gracilis, Hassall. 



Not uncommon on zoophytes and seaweeds, but small and not 

 easily seen. Sandgate, Dover, Westgate, Whitstable, Worthing.

Found upon zoophytes and seaweeds, often in masses of 

 considerable size. Deal, Sandgate, Bexhill, Dover, Folkestone,

Two species of Thuiaria occur in Britain, but I have not yet 

 found either of them. 



If any fellow-members have slides of hydroids which require 

 identification, I shall be happy to assist them to the best of my 

 ability.
