M r . DILLWYN, as well as ourselves, received this new
species of Conferva from Mr. Borrer and Mr. Hooker, who
discovered it on marine rocks in Papa Westra, in the Orkneys.
It is said to spread in patches over the rocks. The filaments
are closely entangled, and, though so far erect as to form a sort
of fine olive-brown turf, throw out branches in various directions.
These branches are often, but not constantly, alternate,
numerous, obtuse, mostly simplei Their joints
scarcely so long as broad, and, after drying at least, their
separations are white and pellucid. The filaments and branches
are rather rigid, though extremely slender.
