18. A. PARASITICA, " body cylindrical ; skin coriaceous, 

 sprinkled with minute warts ; tentacula snort, in six or seven 

 series, varied." R. Q. Couch.

Hah. Coast of Cornwall. " The favourite site for them is on the 

 claw of the corwich crab (M. verrucosa)," R. Q. Couch. In the 

 neighbourhood of Falmouth never found on this crab nor on Pinna 

 ingens, but frequently on Pecten maximus, Buccinum undatum, and 

 on stones, W. P. Cocks. 



" The body, when the animal is expanded, is columnar, with a 

 hard coriaceous skin, sprinkled with minute warts. The tentacula 

 are about one-third the diameter of the oral disc, rather slender ; 

 mouth generally elevated into a cone. This may probably be con- 

 sidered a variety of the Actinia gemmacea, as that kind is liable to 

 so many variations, but it had not the appearance of belonging to 

 that species." ft. Q. Couch. 



Rapp considers this to be the Actinia effoeta of Linnaeus, and the 

 Actinia brune of Cuvier ; but Easter's figure (Opusc. Subs. 143, tab. 

 14, fig. 2.) quoted by Linnaeus, represents an apparently diiferent 

 species ; and Cuvier's description does not agree well with that given 

 by Rapp himself, nor with that of Mr. Couch. 



The Actinia effaeta mentioned in systematic works on British 

 Zoology is referable sometimes to Act. crassicornis, and sometimes to 

 Adamsia maculata. 



19. A. BELLIS, " lody lengthened, the lower part narrow, 

 smooth, the upper enlarged and glandularly warty ; oral disc 

 expanded, lobed ; tentacula in several rows, variegated.' 1 ''
