Veficulated Corallines. 9 



Bloffom, than any belonging to the vvliol^ Tribe of Coral- 

 Hnes. 



Fig. A^ is the magnified Appearance of a fmall Branch 

 of this CoralHne with its curious Veficles. 



In this magnified Branch, at S, we may obferv^e, that the 

 Branches of this Coralline now-and-then terminate in irre(yu- 

 larly contorted tubulin not unlike thofe it begins with . 



I obferved at Brighthelmftone many Specimens of this Spe- 

 cies adhering to Oyfter-fhells, and growing ered: upon them ; 

 thefe were brought to us in a recent State, juft taken out of 

 the Sea. I took a very minute Branch from one of them, 

 together with its Veficles, and plac'd it in Sea-water upon the 

 Stage of my Microfcope, and in a very fhort time I found the 

 Animal in the Branch alive, extending its tejitaculi or claws 

 out of all its Denticles, but the Animal in the Veficle was con- 

 traded, and did not appear to move. 



Fig. C, gives the Appearance of this Branch in the Micro- 

 fcope. Here the Spines, which were folded up in the Veficles 

 of the Branch at Figure A, are all extended in the Figure C,

Sea-Oak Coralline. 



This little creeping Coralline arifes here and there from

 leaf 'd indented Sea-Oak Fucus. This is found in great Plenty 

 on the Sea-fliore near Sheernefs'm the Ifland o^ Sheppey. The 

 fame Coralline is found fometimes creeping on the filiquofe or 

 podded Fucus. 



The Denticles are blunt at the Openings, and placed in 

 Pairs exadly oppofite to each other j each Pair feems to be
