three well-defined white rings, of which the basal 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 
vubida for the red one, should it on future examination prove to be 
distinct, which I am inclined to think is probable.
