There is probably no genus of red algae of this region the species of

Hypnca. Well developed plants of II. musciformis are easily recog-
nized, but practically everything else is vague and doubtful, and our
determinations of other species are ojily tentative. In regard to the-
smaller forms, it seems as if no two authors used the same name for
the same plant, and even the best authors are often inconsistent with
themselves. For instance, J. G. Agardh, 1876, p. 564, under H. cervi-
comis, refers to H. spinella Kiitzing, 1868, PI. XXVI, as a synonym;
under H. spinella (Ag.) J. Ag., on the next page, he refers to the same
plate. We have collections of Hypnca from several stations to which
we do not feel willing to give specific names. H. cornuta reported by
Moseley proves to be Chondria polyrhiza Collins & Hervey.
