Veficulated CoRALLINeE dina 2 3 i | 
In September 1753, 1 received a recent Specimen of one of 
this Species in Sea-water, and had an Opportunity to difco- 
ver in the Microfcope the Form and Motion of the Polype 
that pofleffed the Infide of it, and of tracing the main Body 
through all its undulated Cafe, as it is exprefled in the 
magnified Figure at C. In the fame Plate, Fig. c, is the na- 
tural Size of the Piece magnified. Since this Obfervation, I had 
an Opportunity, in Fane 1754, at Brighthelm/ftone, of feeing 
this Coralline ina more perfect manner; and haye had the 
- Honour of laying the Account of it, with a very curious 
Drawing by Mr. Erez, before the Royal Society, 4. ra. 40.40% 
"The Form of the Veficles is like a Cup, in which the princi- 
ple Parts of the Animals are placed: We have feen them thruft- 
ing out their Claws or Temtacwli in fearch of Prey, and have ob- 
obferved them at the fame time moving their Cups with their 
{crew-like Stalks atPleafure; whilft the whole Trunk of the Po- 
lype in the Infide of the Stem, or horny Cafe, was at the fame 
time affected with their Motions; for they appeared but as fo 
many Arms united to, and of a Piece with, the Body.

This curious Coralline was colleéted on the Sea-coaft near 
Whitehaven, in Cumberland, by that learned and eminent Phy- 
fician Doctor William Brownrigg, F.R.S.; and appears thro’ 
the Microfcope to be of the moft fingular Struéture of any
