Linnaeus, in a note at page 1315 of his Syftem of 

 Nature, Ed. 12. remarks, that the vehicles which we 

 obferve in the ivory-tufted Celleferous Coralline, and in 

 the Goat's -horn Coralline, feem to unite this genus in a 

 natural order to the Veiicular Corallines. 



This genus has likewife an affinity to thofe Fluftras or 

 Sea Matts that have but one layer of cells, particularly 

 the Cellaria avicularia, or Bird's-head Coralline, where 

 there are feveral rows of cells united together in one Sin- 

 gle layer. 



In this fpecies, and in the Cellaria ciliata, or Ciliated 

 Celleferous Coralline, they have fomething lingular pro- 

 jecting from their cells, which is little figures not unlike 

 birds heads, particularly the former, the ufe of which is 

 not yet known. In this fpecies I have obferved in the 

 microfcope while it was alive, in a watch-glafs full of fea- 

 water, thefe birds heads opening and fhutting their beaks 

 all the time that the polypes were extending and con- 

 tracting themfelves in their cells. 



The arrangement of the cells of the Cellaria loriculata, 

 or Coat of Mail Coralline, obliges me to confider the 

 Cellaria farciminoides, or Bugle Coralline, as belonging 

 to this genus ; becaufethe Cellaria loriculata has its cells 

 placed back to back, which has the appearance of tending 

 to the roundnefs of the Bugle Coralline. 



I had formerly ranged the Bugle Coralline with the ar- 

 ticulated Corallines : but the fhape and difpofltion of the
