This Sea Matt has larger cells than any of this genus
that I have met with; they are egg-fhaped at the top,
the lower part of the fides are a little contracted, they
then end abruptly at the bafe. The walls that furround
the cells Teem to be formed of a very ilender tube.
The figure here reprefented was drawn from a fmall
fpecimen, Tent me by the ingenious Dr. David Skene
from Aberdeen : fince which, I have received a mpre
compleat fpecimen from my worthy friend Mr. Parfons,.

this is regularly dichotomous, and is of a brownifh yellow
color; the middle of the cells are almoft tranfparent.

Silken Sea Matt.
This Sea Matt has very delicate
thin leaves, divided here
and there at the extremities,
fometimes in two, fometimes
in three parts, growing together
in tufts, fending forth,
radical tubes, and having but
one layer of cells.

I have fome elegant fpecimens from the Eaft Indies,
that approach very near to this kind, but they have no
radical tubes, and their fides bend inwards.

This elegant little Sea Matt I found growing on a red
pennated cartilagenous fucus, called Fucus Nereideus,
from the Mediterranean Sea.
The cells when magnified appear furrounded by {harp
denticles, with a briftle fituated in the front of each cell,
bending inwards like a horn : the mouths of the cells incline
forward, and their whole femi-tranfparent fubftance
appears full of fmall points. I am indebted for this,
among many other rare fea productions, to my ingenious
and worthy friend Dr. John Fothergill, F. R, S.
