fpecimen which he gathered in Auguft, 1807, on the beach at Yarmouth. 

 It is of the fame nature with that of C. barbata, confiding of feeds immerfed 

 in a pellucid jelly, and furrounded by numerous filaments which wholly 

 envelop it. It is fcattered over the fides of the branches, and has to the 

 naked eye the appearance of being only very young fhoots. 



132. •vertkillata. C. falls dichotomo-ramofis, cartilagineis, craffis, fufco-oli- 

 vaceis ; ramulis verticillatis, incurvis, breviffimis, plerumque bifurcis, un- 

 dique obfeffis ; articulis diametro brevioribus. T. 55. 



133. fponghfa. C. fills ramofis, cartilagineis, craffis, olivaceis, ramulis fim- 

 plicibus, breviffimis, undique iinbricatis ; articulis diametro fub-fefquilongi- 

 oribus. T. 42. 



134. vit/ofci.f C. fills ramofis, flaccidis, craffis, elongatis, flavis ; ramis oppo- 

 fitis, remotis, ramulis minutis, pinnatis, fub-verticillatis, undique obfeffis ; 

 articulis diametro dimidio brevioribus. T. 37. and T. F. 



In September, 1808, the Rev. G. R. Leathes found a fpecimen on the 

 Yarmouth Beach, on which Mr. Turner has favored me with the following 

 remarks. " The fibres grow as defcribed in the Britijlj Conferva, from 

 every 3d, 4th, or 5th dilTepiment, but rather in tufts than in whirls : they 

 are long, fometimes fimple, but moftly three or four times dichotomous, 

 with acute angles ; towards their bafes grow on them fhort oblong dark- 

 brown bodies (whether feeds or capfules it is impoffible from their minute- 

 nefs to determine) cluftered and feffile, but from the collapfing of the 

 juices, often looking pedunculate. The filaments are fo obfoletely jointed 

 that it is difficult to fay, if they are fo in reality or not, though they look 



I I have received fpecimens of Fucus acuhatus and Fucu: ligulatus from Mr. Backhoufe, which are 

 covered with fhort ramuli of the fame nature and appearance with thole of C. mllasa. In the former 

 I found to my great furprize that the aculei are regularly jointed, and that the main filaments, 

 efpecially towards their extremities, have a fimilarly jointed internal tube running longitudinally 

 through them, and occupying nearly half of their width. I was particularly (truck with the refem- 

 blance of the joints to thofe of C. •villosa, and they fully confirm Mr. Turner's opinion, that there 

 is a ftrong affinity between tbefe two plants.
