Varietas corallio cylindraceo, bail vix attenuata. 



This Coral is dragged up in great abundance by the 

 coral -fi fliers on the iouthern coaft of France and Italy : 

 it is always found fingle without branches, and generally 

 adhering to apiece of Red Coral. It is of a white color, 

 and very hard. The lamellae are forty in number, with 

 as many intermediate ftnall ones ; the latter extend to the 

 margin, but do not reach to the bottom of the ftar, like 

 the larger ones. The common or middle flze of this Co- 

 ral is about two inches long, and three quarters of an 

 inch diameter in the broadeft part. 



This is taken by fome authors to be the beginning of 

 the Madrepora ramea ; but the intermediate lamellae or 

 the latter in a crofs fection appear branched ; befides the 

 M. ramea is of a much loofer texture, deeper channelled 

 on the outfide, and of a ferrugineous color. 



There are many other kinds of the Single Star Madre- 

 pores found foflil in England, France, and Sweden ; but 

 I fhall confine myfelf to the defcription of only fuch 

 as I have met with that are recent.
