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

 more friable than leather, and not unlike the dried fiefh

 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 Iiland 

 of Mauritius, and prefented to me by my worthy friend

The cells of this Alcyoniurn are much fmaller than 

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

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

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

 was. brought from CurafToa, in the Weft Indies,.
