three well-defined white rings, of which the hasal ones are very 

 distinct. Several examples of this species were obtained at extreme 

 low water-mark, from a large mass of detached rocks known as the 

 Mewstone, near the entrance to Dartmouth harbour. They were met 

 with on two or three occasions, but were always found nestling among 

 the roots of Laminaria digitata. 



A few weeks since, part of a plant of Laminaria was sent to me 

 from Devon, and among the roots I found six specimens of an 

 Actinia that closely resembled the one just described, excepting that 

 the brown on the tentacula and certain parts of the disk was replaced 

 by various shades of red. These animals differ so little, except in 

 the general colour of the disk and appendages, that until I have an 

 opportunity of examining some more specimens, I must consider the 

 red one as only a variety of the other, and as such I would pro- 

 visionally describe it. This uncertainty obliges me to depart from 

 the old-established rule of giving the specific name from some marked 

 character in the animal, and I must therefore propose the more 

 general title of ornata for the brown species, and suggest that of 

 rubida for the red one, should it on future examination prove to be 

 distinct, which I am inclined to think is probable.
