the identity of the plant here figured with that figured by 
Dillwyn, I think it best to abstain quoting any synonym or 
habitat which I have not recently verified. My figure and 
description therefore have reference alone to the specimens pub- - 
lished by Mrs. Griffiths in Wyatt’s ‘ Algae Danmonienses,’ and 
to such as agree with them in character. I am not very san- 
guine of the validity of this species, and, notwithstanding some 
differences in minor characters, would place it near C. glaucescens, 
to which it is closely related. The general aspect is not unlike 
that species, and the articulations are of about the same length ; 
but here the stem and branches are more flexuous, the ramuli 
shorter im proportion, and the dissepiments are less contracted. 
I am not disposed to place much reliance on any of these cha- 
racters. 
Meanwhile, as the plant has been published in a work of such 
celebrity as the ‘Algse Danmonienses,’ it is right that it should 
have a place in our volumes.
