This Sea Matt, when magnified, has a white femi- 

 tranfparent appearance, full of little dots or points. It is 

 found adhering to fucus's and fhells all round the coaft of 

 thefe kingdoms. It is always brighteft when taken in the 

 greater depths of the fea. There are- frequently little 

 helmet-fhaped bullae on the tops of the cells, which are 

 fuppofed to be the ovaries. 



The figure at D. in tab. 22. vol. 48. Phil. Tranf. 

 was drawn for me by Mr.G. D. Ehret, F. R. S. when we 

 were at Brighthelmftone, in SufTex, while it was alive in 

 fea- water, in June 1754. Here the figures of the polypes 

 are exaclly reprefented as they appeared through the mi- 

 crofcope.

I have often met with this little Sea Matt upon fucus's, 

 both on the coaft of SufTex and Cornwall. Sometimes it 

 is found furrounding their ftems, at other times fpread on 

 their leaves.
