Fronds about three quarters of an inch in length, growing in dense rose-
coloured tufts from other Algæ ; towards their base generally naked,
b u t pinnated or bipinnated above, the pinnæ and pinnulæ opposite,
spreading, obtuse at their extremities. In luxuriant specimens, the pinnulæ
are often again imperfectly pinnated towards their apex. Joints
fine rose-colour, in the middle of the main filament at least eight times
longer than broad, at the summit 8-4 times; every where colourless at
the articulations. Capsules secund, on the upper side of the pinnæ or
pinnulæ, pedicellate, solitary or 2-4 together, with a pellucid limbiis,
and containing 3-5 large sporidia.
This remarkably beautiful Ceramium is so erroneously represented,

and in English Botany, that I had completed my drawing under
the impression that it must be a distinct and nearly allied
