Whilft I was on the Siiffex Coall at Brighthelmjlone^ I firfl 

 perceived the Polypes alive in the Veficles of the denticulated 

 Clafs of Corallines, and particularly in this. Thefe Animals are 

 of a much largrer Size in the Veficles than thofe in the Denti- 

 cles. They are protruded or grow out irregularly here and 

 there, wiih their Veiicles, from the Sides ot the Stem and 

 Branches. We can eafily diftinguifli them in the Microfcope 

 to be united to the Body of the Parent Polype ; which feems 

 to confifl: of Links of fmall Polypes in Pairs, each Pair con- 

 neded to other Pairs by a flefby Line, that runs through the 

 Middle of the Coralline. Here we faw the fmall Polypes 

 of this Species extending their Claws in fearch of Food, as well 

 as thofe of the veliculated kind.
