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 . ot havinghad the advantage of examining any authentically-named spe-cimens, I am obliged to trust to the general accordance of thespecimens here figured with the description given by Carmi-chael. My figure is drawn from a specimen collected by MissBall some years ago at Clontarf, and now in Herb. T. C. D., andit sufficiently accords with such specimens as I have examinedfrom other parts of the coast. If the threads were all of onediameter, and all built of a double row of cells, there could beno difficulty in ascertaining the identity of the species; butunfortunately this is far from being the case in any specimen Ihave seen. The character by which E. Ralfsii differs is, thelarge size of the cells and the minuteness of the grain of endo-chrome in each. This, in the specimens seen, is very far it may be of specific importance I cannot say. Fig. 1. Enteromorpha percursa:—the natural size. 2. Portions of fila-ments of various sizes :—highly magnified.
