Duobus diversis stratis frons cava contexta est; cellulae exteriores minores, rotundatae, interiores majores, poly- gonatae, glandulas pyriformes acervatim gerentes. Caules solidi, textura parenchymatica. The plant (Fig. 8) reaches a height of about 4^2 cm. (the largest specimen collected, the smaller ones were only two cm.). It is fastened to the substratum (stones, shells etc.) by means of a rather large, flat disc; from this one or more, erect ramified shoots grow up. The stem of these erect shoots is terete and solid; it bears the swollen, hollow, short shoots. The shape of these is obovate-pyriform reaching a length of about 8 mm. and a breadth of 5 mm.; the wall is about 90 ^ thick while the hollow in the interior is filled up with slime. The plant is when living somewhat trans- lucent. With the exception of the stem, which is firmer, it is of a rather soft and slimy con- sistency and adheres strongly to the paper. The colour is red with a yellows-brown tinge. As to the anatomy of the thallus, we find the membrane of the vesicles consisting of a layer of large cells (Fig. 9 A), which on their outer side are covered more or less com- pletely by a layer of small cells (Fig. 9 B). Seen from the surface the innermost large cells show themselves to be roundish polygonal (Fig. 9 J5, C). On the upper side over the transverse walls of the large cells, where some more space is left on account of the somewhat curved surface of these cells, we find a row of roundish cells and from these again smaller and smaller roundish and flat
