D is c o v e r e d in the sea at Bantry bay, by Miss Hutchins,
from one of whose specimens, sent to Mr. Turner, our drawing,
as well as Mr. Dillwyn’s, is made. It grows in close straight
tufts, 2 or 3 inches high, of a bright green, paler and blueish
when separated. Filaments capillary, flaccid when dry, much
and irregularly branched in their upper part chiefly, the
branches but little spreading, sometimes almost parallel to
each other. The joints are very slightly tumid;'appearing
clouded internally when dry; but their contents are not, in
that state, so much condensed as in many other species. The
lower joints are scarcely at all longer than broad, but the
upper ones are gradually more so, and the length of the ultimate
branches is 7 or 8 times as great as their diameter.
It is necessary to mention that our C. isogona, t. ] 030,
must in future be called C. Youngana, under which name it
appears in Mr. Dillwyn’s t. 10 2 . We had no idea of the
worthy author’s intention, and we therefore rely on his pardon
and that of his friend, €C unity fuiblukd hu -£u,ulon.
