it adheres most closely to paper. The colour is a bright rosy-red. No 

 fruit has been seen. The periphery is pierced with large lacunae, with 

 cellular walls ; the cells small, angular, and coloured. 



A rare and beautiful species, for a knowledge of which I am 

 indebted to my excellent correspondent, whose name it bears, 

 and who has repeatedly taken it, after storms, at TYemantle. 



It is nearly related to C. Muetteri, Sond. (also found by 

 Mr. Clifton), but is of a much brighter colour, a softer and 

 more gelatinous substance, and, above all, differs in the wide 

 "isthmuses'' (so to say) between the articulations. In C. 

 Muetteri the internodes are connected by very slender, seta- 

 ceous pedicels. It may also be compared with very luxuriant 

 specimens of the European C. articulata, from which also it 

 differs in substance and colour, and in the shape of the inter- 

 nodes. It is possibly one of the plants to which the Australian 

 " Fucus articulates " of Brown, in Flinch App. p. 594, should 

 be referred ; but more probably that synonym attaches to 

 Chondria opwitioides, a much more common plant, or to some 

 species of Erythroclonium. All these Algse have a similar ex- 

 ternal habit, though differing widely in structure and fructifi- 

 cation.

 young ramuli. 3. Portion of the periphery : — the latter figures more or 

 less magnified.
