C. filamentis ramofiflimis venofis purpureo-nigrefcentibns ; ramis t

 ramorum obfoktis, ramulorum diametro fub-longioribus. 



Rocks in the Sea. Near Forres ; James Brodie, E/q. Bantry Bay, Mifs Hut chins. 

 At Falmouth ; Mr. Turner. At Scaton, Devon -, Mr. Griffiths. Sometimes 

 thrown on the fhore at Dover. 



OF this fpecies I fivft received fpecimens from Mr. Brodie, and have named 

 it after him as an acknowledgement of the kind attention with which he ha* 

 honored me, and of the affiftance which he has given to this work. 



C. Brodisei is among the mod magnificent of the genus, often extending to a 

 foot and a half or two feet in length, and pufhing forth from a difcoid bale 

 feveral main filaments as thick as fmall twine and of a blackifh purple color. 

 Thefe are befet with fcattered branches of uncertain length, which arife in a 

 direaion between horizontal and patent : along the branches at irregular inter- 

 vals clutters of Mender ramuli are difpofed, from a quarter to half an inch long, 

 multifid in a fub dichotomous manner, and acuminated at their apices. The 

 whole of the branches and ramuli are of rich deep red-brown color when frefh, 

 but turn black on drying, and are always ftrongly marked with dark longitudinal 

 veins. The capfules are ovate, fefiile, and plentifully fcattered over the ultimate 

 ramuli, fometimes on their fides, and fometimes at the axilla: of the divifions. 

 Befides thefe C. Brodixi, in common with mod other of the marine fpecies, 

 prefents what is ufually confidered as another kind of fruaification, confiding of 

 fphxrical globules imbedded in the ultimate ramuli, but of their real nature I 

 confefs that I am unable to fatisfy myfelf.
