Here there was typical Glycerietum with hummocks of Glyccria maritima, and the other halophytes noted were Limonium humih (L.H.), Aster Tripolium (A.T.), Salicornia herbacea (SAL) and Suacda maritima (D.M.); the last two spread to the muddy shingle beyond the Pelvetia zone. Gelatinous clumps of the Blue-green alga, </p><p>Rivularia atra (Biv), were abundant on the surface of the marsh. </p><p>The algal vegetation of Mahee Island was not examined in detail, but at various points where records were made the zonation was similar to that of Skettrick Island which was mapped in detail. </p><p>REFERENCES. </p><p>(1) Lynn, M.
