Haddon and Shackleton — A Revision of the British Actinice. 625 



coelenteric canals of the Zoanthean. The capsules are paired, and contain a large 

 number of ova. We have these in the nauplius stage, and in other stages of 

 development. We have two specimens of the Copepod, but are unable to say 

 whether these are adult or not. The capsules form distinct swellings (PI. lxi., 

 figs. 19-22) of the body- wall of the Actinian. This fact leads us to suppose 

 that the Copepod remains within the ccelenteric cavities while the capsule is 

 developing ; and when the latter is ripe it breaks away from it. 



We have sections of a Crustacean in the ccelenteron of the only specimen of 

 Episoanthus macintoshi (from Shetland) we were able to cut, but we cannot say 

 anything more about it. 



Small, oval, deeply pigmented bodies occur in many parts of the body in 

 Parazoanthus dichroicus and in P. douglasi (PI. LXii., figs. 5 and 6). They are 

 evidently parasites, but we have been unable to determine their nature. 



Problematical rounded bodies, which stain deeply and uniformly with carmine, 

 are present in Z. macgillivrayi, Palythoa howesii, and other species.
