, Hub. On fuci beyond low water mark, on stones and 
j.dls from deep water ; common. Parasitical on Alcyonium 
H'S'tatmn, or dead man's hands, and other corallines; very 
f °nimon, from the Rame Head to the Lizard, and ten leagues 
r °ni the shore. 
There are two varieties of this species, both alike com- 
a ! the first, where the stem is composed of a single fibre 
. sparingly branched, rarely exceeding two inches in 
®*§ht ; the second, where the stem is composed of a 
at nber of tubes twisted on each other and growiug to 
i s e height of six inches. In the last variety, the polypidom 
er ect, rigid, and rooted, with tubular fibres which are 
v ° s ely malted together. I have a line specimen from deep 
a ^ er , growing in a large tuft, ten inches in height.
