Commingled with these charming Roses, there are others which attain a
larger size, occurring in even greater abundance. They are frequently
an inch and a half in diameter when expanded, and some are even larger
than this. You may know them at once by observing that the outer row of
tentacles, and occasionally also some of the others, are of a scarlet
hue, which, when examined minutely, is seen to be produced by a sort of
core of that rich hue pervading the pellucid tentacle. The species is
commonly known as the Scarlet-fringed Anemone.[37] The inner rows of
tentacles, which individually are larger than those of the outer rows,
are pale, marked at the base with strong bars of black. The disk is
very variable in hue, but the column is for the most part of the same
rich brown as we saw in the Rosy. Yet, though these are characteristic
colours, there are specimens which diverge exceedingly from them, and
some approach so near the Roses, as to be scarcely distinguishable
from them. Generally, however, the scarlet-cored outer tentacles,
and a peculiar habit of throwing the tentacular margin of the disk
into crumpled folds, will be found sufficient to determine this very
handsome kind of Anemone from its nearest allies.
