The name of Sea Hair, applied to this species, is ve 
characteristic of its general appearance, and to an matte 
observer it would pass for something of the kind, as 
exposed on the shore. It grows plentifully all round 
rocky shores on the stalks of the larger sea weed, a g( 
beyond low water mark. On the south eastern l ,al . - t , 
our coast, it occurs most commonly as short, delicate .</ 
like fibres on the stalks of the Laminaria digitala, and ra • 
exceeding an inch and half in height ; but frequently « 
a storm, clumps, as large as a child’s fist, are waslici a» ^ 
from deep water. About Mevagissey, Goran, and we- 
the Headman point in Veryan bay, it occurs 10 D, * s ^‘ > ^ 
large as a child’s head, or even larger. Mr. Peach o W 
has some very fine specimens in his collection, and 6 
some equally 'fine, from the same neighbourhood. I “j, 
been informed that several years ago, many cartloads of y 
Zoophyte were drawn on shore in a trawl net at Me van 
and sold as manure ; whether this is true or not, it ls r t 
tainly more abundant and finer there, than on any other t ^ 
of our coast that I have examined. It is of a van 
brown colour, very slender and elegantly waved. 
shoots arc numerous, alternate and of equal size to the ^ fl (f 
It does not like the rest of the species of this genus, 
its branches from a continuous trunk, but the oflsets ^ 
quenlly become the continuations of the height 
polypidom. It is divided at short intervals by imp°ji> 
septa ; the internodes join each other in straight lines, 
consequence of their being so sleuder, they yield 10 
other, and give the polypidom a zig-zag or gently ' ‘ c li 
appearence." The cells are opposite, in single pairs °° ^ e H 
inlernode, and attached through the greater part ot . ^ 
extent; their apertures, are not everted like those o 
others of this genus, but look upwards; the external e 
the aperture is continued into a slender aente point, ^fl/ 
beside two large lateral teeth. The vesicles are irreg' jo' 
distributed over the polypidom, of a long egg-form; J „ t» 
ferior portion is pedunculated, the superior truncated ' |f / 
operculum, and they are most plentifully produce* , -W 
December to April. In the figure of this species g » 
lillis in his essay on Corallines, the lateral teeth ot ^ g jd 
are omitted because the specimen was not “ placed i 
view for the painter when it was drawn. ’
