I am doubtful whether the superb specimens of 
Polypi deposited by me in the Society's collection, 
actually belong to the species here named, or are as yet 
undescribed. The account by Ellis is very meagre, 
saying nothing of the form or coloration of the polyps; 
and the figure by Shaw is but little more satisfactory. 
I have not seen the other figures above referred to. If 
the species are identical, our specimens attain probably 
a larger size, and are more beautiful than their fellows of 
the European shores. I have seen isolated specimens 
of at least a foot in length, with the peduncle the size 
of a large straw, and the polyps one and a half inches 
in diameter. 'The stems are usually of a pale flesh 
color, the tentacule somewhat darker, and the central 
portion a deep crimson, often filled with pendulous clus- 
ters of ova of a lighter color, in form like minute clusters 
of grapes. It is impossible to imagine a more beautiful 
object than is presented by a group of these animals, 
seen in the clear water by a bright sunlight, as they 
-wave to and fro in the current. In the delicacy of their 
petals, if they may be so termed, and the depth and 
brilliancy of their colors, they are equalled by few of 
the flowers of earth.
