Han. East Coast, Mr. Colenso. Bay of Islands, Lyall. 
Our specimens, apparently broken, are 5-6 inches in 
length, and not aline in breadth. The main stem, from loss 
of membrane and thickening of midrib, is narrower than the 
branches. It is irregularly divided at a few long intervals 
into principal branches, which are bare of ramuli in their 
lower part, but closely pinnated and sometimes bipinnated 
above, the pinne very erect. Every part of the frond is 
regularly inciso-serrate, the serratures being from 4 a line to 
nearly a line in length, and about as much asunder, alternate, 
subulate, acute. The midrib, which is evident below, be- 
' comes very faint upwards, and is gradually lost in the 
younger portions of the frond. The colour of our specimens 
is a dark reddish brown, fading to white on macera- 
tion. The substance is rigid, thickish, and it does not 
adhere to paper. Under a lens of lower power, the frond 
appears closely striate transversely, owing to the arrange- 
ment of the cellules in the interior of the frond; under a 
higher power this character is lost, as the cells of the peri- 
phery, which are small and more opake, obstruct the view. 
The stichidia are produced in great abundance along the 
midrib, which eventually they completely cover. Our plant 
is much less branched than Turner’s F. lineatus, with longer 
and straighter branches, a more rigid and thicker substance, 
and a different colour.

Has. New Zealand, Sir Joseph Banks. 
No one has gathered this species at New Zealand since 
the time of Banks, whose specimen is vouched for by Turner. 
We earnestly hope some of our friends at New Zealand may 
re-discover it. Le
