Sea Matt was brought from Weymouth, in Dorr
fetfhire, and was found adhering to the Fucus digitatus.
There are difperfed here and there, at regular diftances
over the furface, little tranfparent, ffiort, eredt tubes;
but to what ufe I ftiall not pretend to determine, unlefs
they are the ovaries.

Linnaeus, in a note at page 1315 of his Syftem of
Nature, Ed. 12. remarks, that the veficles which we
obferve in the ivory-tufted Celleferous Coralline, and in
the Goat’s-horn Coralline, feem to unite this genus in a
natural order to the Veficular Corallines.
This genus has likewife an affinity to thofe Fluftras or
Sea Matts that have but one layer of cells, particularly
the Cellaria avicularia, or Bird’s-head Coralline, where
there are feveral rows of cells united together in one fin-
gle layer.
In this fpecies, and in the Cellaria ciliata, or Ciliated
Celleferous Coralline, they have fomething lingular projecting
from their cells, which is little figures not unlike
birds heads, particularly the former, the ufe of which is
not yet known. In this fpecies I have obferved .in the
microfcope while it was alive, in a watch-glafs full of fea-
water, thefe birds heads opening and ffiutting their beaks
all the time that the polypes were extending and contracting
themfelves in their cells.
The arrangement of the cells of the Cellaria loricul.ata,
or Coat of Mail Coralline, obliges me to confider the
Cellaria. farciminoides, or Bugle Coralline, as belonging
to this genus; becaufe the Cellaria loriculata has its cells
placed back to back, which has the appearance of tending
to the roundnefs of the Bugle Coralline.
I had formerly ranged the Bugle Coralline with the articulated
Corallines : but the ffiape and difpofition of the
