Shepherd's-purfe Coralline. 



This moft beautiful Pearl-coloured Coralline adheres by 

 fmall Tubes to Fucuss^ from whence it changes into flat 

 Cells ; each fingle Cell like the Bracket of a Shelf, broad at 

 Top, and narrow at Bottom : Thefe are placed Back to 

 Back in Pairs, one above another, on an extremely flender 

 Tube, that feems to run through the Middle of the Branches 

 of the whole Coralline. 



The Cells are open at Top. Some of them have black 

 Spots in them : And from the Top of many of them, a Fi- 

 gure fcems to iffue out like a fliort Tobacco-pipe ; the fmall 

 End of which feems to be inferted in the Tube that paffes 

 through the Middle of the whole. 



The Cells in Pairs are thought by fome to have the Ap- 

 pearance of the fmall Pods of the Shepherd's Purfe : By others, 

 the Shape of the Seed-Veflels of the Flerb Veronica^ or Speed- 

 well.
