Milleporaalcicornis. Linn, Syft. Nat. Ed. 12. p. 1282.
The pores of this Millepore, as it is generally brought
to us, are fcarce vifible; but when they come from the
Weft Indies, preferved in fpirits, they are very diftin-
guifhable, each appearing funk in a little cavity : in the
dried fpecimens they appear level with the furface, and
o f two ftzes, larger and fmaller. This is one of the com-
moneft of the Corals in the Weft Indies, and ufed principally
for burning into lime. It is found in a variety of
forms, fome with round irregular branches, others pal-
mated, which end in taper figures, like fingers ; as thefe
branches grow up, they frequently unite together, forming
new palmated branches that end in flender digitated
forms. This Coral Js often found invefting the dead
ftems of the Gorgonias, where it appears like fo many
beads of a necklace.
Sir Hans Sloane, in his Hiftory of Jamaica, has given
a figure of a bottle that was taken out of the fea in-
crufted with it. This is now to be feen among his curious
collection of Corals in the Britifti Mufeum.

This
This Coral grows in immenfe mafles in the Eaft-Indian
Ocean; it is now and then brought us from Prince s
Ifland, in the Straits of Sunda. The laminae, or plates,
are generally half an inch thick, and full of minute pores
between the cellular ftarry cells, which both pafs from,
each furface to the central longitudinal veffels in nearly a
perpendicular direction, and with which they are united.
The furface of this Coral, when magnified, is full of little
fharp points between the fmall pores and round the
larger ; and when we examine the larger ftellated pores,
we find them furrowed on the infide to the bottom,
which makes a proper tranfition from this genus to the
Madrepores.

The animal of the Pipe Coral
is unknown.
The ftem is ftony (that is
coral) with tranfverfe partitions,
uniting together the
perpendicular tubes.
Thefe tubes are jointed,
communicating with one another
by means of geniculated
pipes, which pafs through
each of them, and are radiated
at their joints.
