This curious variety, which was found on the Yarmouth Beach by Mr. 

 Hooker, in the fpring of 1808, attached to a piece of deal, differs fo ex- 

 traordinarily from the common appearance of C. area, that except under a 

 microfcope nobody would fufpecl them of being the fame. It grew in a 

 very large tuft, and its filaments were remarkably foft, tender, ilippery 

 and gloffy, fo as to float with the flighteft agitation of the water and adhere 

 clofely to paper and glafs in drying.

The mode of growth, color and habit of this plant, which was firft dis- 

 covered on the coafl; of Sweden by Meffrs. Weber and Mphr, are precifely 

 fimilar to thofe of C. area, from which it differs in the fomewhat greater 

 thicknefs of its filaments, and greater length of its joints. It was C. mela- 

 gonium of which fome years ago I found a fingle filament on the fhore near 

 Swanfea, and which I then confidered as a variety of C. area, and as fuch 

 it is mentioned in my defcription of that fpecies. The drawing at T. B. 

 was made by Mr. Hooker from a dried fpecimen, and reprefents the plant 

 of its natural fize, and alfo when magnified 3.
