Natural Hiftory of 
The firft fort.is found in Plenty, growing ere& on Oyfters, 
near Queenborough in the Ifland of Sheppey. ‘This is very little 
branched ; the Stem is flender, and twifted a little between 
the Denticles like a Screw: The Denticles are large, pitcher- 
fhaped, and placed alternately. When this Coralline was 
taken out of the Sea-at Queenborough, and kept immerfed a 
little time in Sea-water, I obferved, through the Microfcope, 
a Polype occupy the Infide of the whole, and each Denticle 
filled with a Part of it, ending in Tufts of tentaculi, or fine 
hair-like Claws, as exprefled in Plate Il. Fig. 4 moving 
about very {wiftly. The Veficle is added here, to thew its 
magnified Proportion to the Denticles ; but the Animal Was

paration of its Body, in five Minutes time the Claws were 
moving about in fearch of Prey.

branched, the Denticles are placed more afunder, and their
