CAPNEAD^. 
Ill August, 1856, the Rev. J. P. Greenly, being on a 
visit to Ilfracombe, found in a crevice of the slaty rock at 
Bull Point, at extreme low water, this magnificent species, 
which lived in his possession till the following April. To 
his courtesy I owe copious descriptions and drawings made 
from the animal while in life and health ; by which I am 
enabled to draw up the foregoing diagnosis. I forwarded 
to him for comparison some drawings which I had by me 
of Mr. Thompson’s Corynactis heterocera / and the agree- 
ment of the two forms in all essentials, and especially in 
the singular shapes of the diverse tentacles, showed that 
they were of one and the same genus, which was thus 
proved to have characters that called for its separation from 
Corynactis. At the period last named my kind corre- 
spondent forwarded the specimen to me : but it was already 
dead; and while it retained its form and colour, I was 
precluded from adding anything to my knowledge from 
personal observation. 
In captivity the animal was lively and extremely sensi- 
tive, retracting its disk with remarkable suddenness and 
rapidity on alarm. It early crawled from the piece of slate 
on which it was captured, and took up a position on the 
side of a finger-glass in which it was kept. The tentacles 
were observed to vary the shape of their knobs, within 
slight limits : one here and there in the outer row occa- 
sionally approaching the hastate form of the next row.
