form a beautiful little grove-like figure of this animal.
This moft elegant fpecimen I have preferved in fpirits.
The figure of this animal, without its ovaries, was.
drawn by Mr. Ehret, in June 1754, at Brighthelmftone*
and is reprefented in the Philofophical Tranfa&ions,
Vol. 48. tab. 22. No. 1. A. to fhew the medullary part
of this animal in the ftem, united to the feveral heads in
their cup-like denticles. This is a moft exadt figure o f
one of thofe on the Afcidia before mentioned, when
viewed through the microfcope in fea-water.- The figure
at tab. 12. fig. B. Eflay on Corallines, has the ovaries*
but not the cup-fhaped denticles : this was taken from a
dried fpecimen, where the joints are very much fhrunk, fa
as to look knotty.

ovaries are egg-ffiaped, and
end in a tube.

Since I published my Eflfay on Corallines, I have met
with fome fpecimens, with their ovaries, which were o f
an oval figure, ending in a tubular mouth.
This Coralline is remarkably tender and brittle, and:
the bell-fhaped denticles are fo glutinous* that it is very

expanded. The ftalks that fupport them- are very elegantly
twifted, like the ftems of fome modern drinking

There are.different varieties and fizes of this twining
bell-fhaped Coralline, from one quarter to three quarters
of an inch long ; particularly the branched fort in tab. 4.
fig. e. f. E. F. which is very rarely met with. This has
wrinkled ovaries, but moft of the others are fmooth.
Thefe are all found climbing up and growing upon other
veficular Corallines ; moft of them are to be met with on
the coaft of Suflex.
