Fructificatio ignota. All the specimens found were sterile so in referring them to Wrangelia I have only had the vegetative thallus to rely on, but this shows so much likeness to the other species of Wran- selia that I have no hesi- tation in referring it to this genus. As being especially characteristic of this plant may be mentioned the fact that the cor- tical layer is not much developed and that the apices of the assimilating filaments mostly end in two short acute conical cells. Wrangelia bicuspidata is a sublitoral alga growing in rather deep water, 20—30 meters or more. It is an epiphyte, as in the case of Wrangelia penicillata found upon different large algæ, e. g. Caulerpa, Halimeda, Avrainvillea etc. and is fixed to these by means of thin rhizoids growing out from the lowermost parts of the filaments. The plant has a beautiful rosy colour and forms loose, flabby tufts up to seven cm or more in height (Fig. 127). The principal. Fig. 128. Wrangelia bicuspidata nov. spec.
