I found this little Coralline, adhering by its radical
tubes to a fpecies of Fueus,. called by Linnæus, Fucus
lendigerus. In the plate I have given a figure of the
Fucus with the Coralline creeping up it, of its natural
fize. It was taken up at fea by an Eaft-India fhip on
the coaft of Africa, not far from the ifland of Afcenfion.

adhering tube.
This Coralline is about two inches high, very llen-
der, and of a bright yellow color. It creeps on fucus’s.
The ovaries differ from all the reft of the genus: they are
lobated, and the lobes are placed oppofite to one another:
thefe appear to be full of fpawn, of a deep orange color,
which is fent forth from holes at the endot the lobes.
This was firft difco'vered by Mr. John Evans, a fea-
officer in the Eaft-India Company’s fervice, among fome
fea productions brought from Yarmouth, in Norfolk, in
the year 1767.

Dr. David Skene, of Aberdeen, firft difcovered this
Coralline. The fpecimens he fent me were imperfedt, as
wanting the denticles ; they feem to be, by what I could
judge of the ftalks and imperfedt pieces, not unlike the
