This seems to be a perfectly distinct as well as abundant species on
the Western Coast of the United States and along its whole extent. The
specimens distributed are those of the smaller form occurring on exposed
shores on Phyllospadix, those under (a) representing the stages where the
membranous portion is developed, while those under (b) have little more
developed than the prothalloid basal portion which is peculiar to this spe-
cies.
