Abstract
THE new work of Dr. Agardh, forms the third part of a series of monographs of algæ, two parts of which have already appeared. The first part contains the genera Caulerpa, Zomaria, and certain groups of Sargassum; the second contains the Chondariaceæ and Dictyoteæ. The Ulvaceæ form the subject of the present monograph. This work should have special interest for algologists, from the circumstance that in it the author has expressed his views, and the reasons on which they are founded, concerning the much-debated question whether Bangia, Porphyra, Goniotrichum, and Erythro-trichia belong to the Florideæ or to the Ulvaceæ. The fact that Dr. Agardh still retains them among the Ulvaceæ is a sufficient proof that he is not convinced by the perusal of Dr. Berthold's work (noticed in NATURE, vol. xxvii. p. 385), and the statement of the latter that they belong to the Florideæ.
