Varietas corallio cylindraceo, bafi vix attenuata. 



This Coral is dragged up in great abundance by the 

 ■coral-fifhers on the fouthern coaft of France and Italy : 

 it is always found fingle without branches, and generally 

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

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

 as many intermediate fmall 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 fize 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 raraea ; but the intermediate lamellae of 

 the latter in a crofs fection appear branched ; befides the 

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

 on the outride, and of a ferrugineous color. 



There are many other kinds of the Single Star Madre- 

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

 I fhall confine myfelf to the defcription of only fuch 

 as I have met with that are recent.
