the Chordaria australis of J. Agardh, who is now inclined, 
with us, to regard it as the type of a new genus, allied to 
Chordaria and Mesogloia. Our friend, M. Montagne, on the 
contrary, considers it one of the Floride, allied to Grateloupia, 
an opinion from which, for many reasons, we are compelled 
to dissent.

An attentive perusal of Turner’s characters of his Fucus 
lineatus has convinced us that it must be something very 
different from Amansia multifida, to which Agardh unites it. 
The description has so much in common with the following 
species, which does not however answer to the figure, that 
we venture to refer the Banksian speciss to the present 
genus.

* To this genus also belong Fucus fraxinifolius, Turn.; (E, fraxinifolium, —

tially in the position of the fructification, and in habit. I have another 
unpublished species (E. Backhousii) from the Swan River.—W, H, H.
