This moft curious fea produ&ion grows on fucus's and 

 ftones on the coaft of Cornwall and Wales. 



We have but an imperfect figure and account of it in 

 Rondeletius ; but my worthy friend the late Dr. SchlofTer 

 has given us a very good figure and defcription of it in 

 the Philofophical Tranfa&ions. The Rev. Dr. William 

 Borlafe, in his Natural Hiftory of Cornwall, haslikewife 

 given us a figure of two kinds ; one with a hole at each end 

 of the rays, befides the central hole in the epidermis ; and 

 one with only one hole in each ray, and that on the broad 

 part, which he takes to be the fame with Dr. Schloffer's; 

 but I find that the two kinds, mentioned by Dr. Borlafe, 

 are one and the fame animal, and this appears very clearly 

 from a fpecimen fentmefrom North Wales, by my inge- 

 nious friend Thomas Pennant, Efq. where the ftars on it 

 anfwer to both kinds ; for fome of the rays have only one 

 hole, which is on the obtufe end, but the greater!: num- 

 ber of the ftars have a fmall hole at the narrow end of the 

 rays which turns up, befides the hole on the broad part : 

 ■fometimes thefe holes at the fmall end join all together 

 in a circle, and the opening of the outward fkin, or
