yellow-green, glossy when dry. The substance is very soft, silky, and flaccid, 

 and in drying the plant adheres pretty closely to paper. 



In ramification, and in the great length of the articulations, 

 this elegant species agrees with C. Feredayi (Plate XLVIL), 

 from which it differs in being of smaller size, in the much greater 

 tenuity of the filaments and especially of the upper branches 

 and ramuli, in the very soft substance and yellow-green colour. 

 It is not likely to be confounded with any Australian species, 

 but agrees in several respects with some from Japan ; and in 

 ramification with the European C.pellucida and its allies. 



The first specimens I saw were observed in a book of care- 

 fully dried and well selected Algse, prepared by Mr. Baines, of 

 Melbourne, for exhibition in the Victorian " Crystal Palace," and 

 which were, I believe, afterwards contributed to the Paris Ex- 

 hibition of 1855. The book was sent to Dr. Eerd. Mueller and 

 myself for our inspection, previous to being forwarded to the 

 Exhibition, and we agreed to affix Mr. Baines's name to this 

 new species of his discovery.
