Phycologia britannica, or, A History of British sea-weeds, containing coloured figures, generic and specific characters, synonymes, and descriptions of all the species of algae inhabiting the shores of the British Islands . , is a very different plant, having a verdigris-green colour,and being thrice as slender. As a genus, Lyngbya is intermediate between Oscillatoria andCalothrix. From the first it differs, by having long, flexible fila-ments, destitute of oscillatory motion; and from the latter, byits stratified habit. There are several species, the most commonof which is a terrestrial one (L. muralis), which forms a silkystratum of a brilliant green colour on the surface of dampground, and abounds everywhere, and at all seasons. The majorpart of the species, are, however, marine; and, besides the pre-sent individual, three others are found on our coasts, and willbe figured in a future number. The genus Bangia has many points in common with Lyngbya,and is even united to it by Mr. Hassall, but if these genera are tobe combined, Bangia, being the older name, must be adopted. Fig. 1.
