The fubftance of this Alcyonium, now it is dry, is 

 more friable than leather, and not unlike the dried flefh 

 of moft of the Gorgonias. It is two* inches and a half 

 long, and one inch and a half high ; it feems to have ad- 

 hered to a rock. It was found on the coaft of the Ifland 

 of Mauritius, and prefented to me by my worthy friend^

The cells of this Alcyonium are much fmaller than 

 thofe of the A. mamillofum or A. ocellatum beforemen- 

 tioned, but are compofed of the fame number of rays,

 rocks and corals ; and in the fpecimen here figured, it is 

 incrufting the Sertularia frutefcens. I received this fpe- 

 cimen from Dr. Pallas, who fent it to me to convince me

 tularias with the Gorgonias, and gives it the name of Ser- 

 tularia Gorgoniain his book on Zoophytes, pag. 158. It 

 was brought from Curaflba, in the Weft Indies.
