This is one of Sir Hans Sloane’s firft beginning of the
Aftroite Corals. Specimens of this and the former are in
the Britifli Mufeum.
I have received fome fpeeimens of this preferved in
fpirits from Mr. Greg, from Dominica; they are of a
tough vifcid nature, and appear to have fome fine fand
mixt in their texture. They fpread over rocks with a
fingle fuperficies of cells,, as the Fluftra does on fucus’s,
and fhells, but never rife into branched figures, that I have
yet feen. They have twelve rays..

The fubftance of this Alcyonium, now it is dry, is
more friable than leather, and not unlike the dried flefb
of moft o f the Gorgonias. It is two inches and a half
long, and one inch and a half high ; it feems to have adhered
to a rock. It was found on the coaft of the Ifland
of Mauritius, and prefented to me by my worthy friend
Dr. John Fothergill.

The cells of this Alcyonium are much fmaller than
thofe of the A. mamillofum or A. ocellatum beforemen-
tioned, but are compofed of the fame number of rays,
that is, twelve to each cell. It is often found incrufting
rocks and corals ; and in the fpecimen here figured, it is
incrufting the Sertularia frutefcens. I received this fpecimen
from Dr. Pallas, who fent it to me to convince me
that he had found a new Sertularia, which united the Ser-
tularias with the Gorgonias, and gives it the name of Sertularia
Gorgoniain his book on Zoophytes, pag. 158. It
was brought from Curafioa, in the Weft Indies*
