1. Sagartia rosea. 



2. S. hell is. 



3. S. sphi/rodefa. 



4. S. troglodytes. 



5. Bunodes gemmacea. 



6. Bunodes Ballii. 



The last, B. Ballii is altogether unmentioned in his list as occurring 

 in any of the provinces. The only ones he records as occurring from the 

 west province, are as follows — 



1. Actinolola dianthus. 



2. Sagartia hellis. 



3. S. venusta. 



4. S. viduata. 



5. Anthea cereus. 



6. Actinia mesemhryanthemum. 



7. Tealia crassicornis. 



Sagartia Parasitica. — Since writing this paper, I have had the good 

 fortune to be able to add another species to my list, viz. Sagartia para- 

 sitica, which in Ireland has been only recorded from Bantry Bay. Hav- 

 ing purchased some cockles from a vender at the door, I remarked that 

 the greater number of them had adhering to them an anemone which I 

 had never seen before. 



On consulting Gosse, I had no difficulty in identifying Sagartia 

 parasitica. I append some of the principal points in his description : — 



" Colour. — Column, ground-colour, a dirty white or drab, often 

 slightly tinged with pale yellow; longitudinal bands of dark wood- 

 brown, reddish or purplish brown, run down the body, sometimes very 

 regularly, and set so closely as to leave the intermediate bands of ground- 

 colour much narrower than themselves. 



" Tentacles. — Pellucid, faintly tinged with flesh-colour, cream-yel- 

 low, or purplish, each marked with a dark-purplish or brown line down 

 each side, which is broken into about five dashes. 



*' Size. — It frequently attains a height of 4 inches, with a diameter 

 of 2| in column, and 3^ in flower." 



The specimens I examined agree very weU with the above descrip- 

 tion, the tentacle markings being very plain and distinct. In size, how- 

 ever, my largest was only fths of an inch in diameter, and the column 

 appears to be covered by a transparent mantle, of firm consistency, 

 through which the longitudinal buff and purplish-brown bands are 

 plainly seen. This may be peculiar to young individuals. Gosse de- 

 scribes it as being parasitical on univalve shells (such as Turritella tere- 

 hra, Trochus magus, T. %iziphinus, and Buccinum undatum), which are 

 tenanted by a soldier-crab, and occasionally on stones. 



Mr. R. Couch says: — '' That the favourite site for the anemone (in 

 the neighbourhood of Penzance) is on the claw of Maia squinado."
