As an appendix to the above, I have been permitted to subjoin 

 a few remarks upon the services rendered by our late regretted 

 colleague, Mr. T. H. Buffham, to algological science, in which 

 my chief purpose has been to make his labours in their entirety 

 better known. It was the reproductive organs of the Florideae 

 which mainly attracted the attention of our deceased friend. 

 In a large . number of these algoe the fecundating organs, 

 that is to say the antheridia or, as they are designated by 

 Schmitz, the spermatangia, were either unknown or imperfectly 

 described. Mr. Buffham had the repeated good fortune to 

 collect many species provided with the male apparatus, and his 

 descriptions of them are to be found in four memoirs published 

 in the Journal of this Club between the years 1884 and 1893. 

 (" Journ. Q.M.C.," Ser. II., Vol. i., p. 337-344, Plates X.-XII. 

 [1884] ; Vol. iii., p. 257-266, Plates XX.-XXII. [1888] ; Vol. iv. 

 p. 246-253, Plates XV.-XVI. T1891] ; Vol. v., p. 291-305, Plates 

 XIII. XIV. [1893].) Amongst the species in which Mr. Buff- 

 ham has represented the spermatangia may be mentioned the 

 following, arranged in the chronological order of the publica • 

 tions in which these organs are illustrated : — I. (1884). Galli- 

 thamnion tetricum, Gallith. byssoides, Spermothamnion Turneri, 

 Antitliamnion plumula, Griffithsia corallina, Ptilota elegans, Gera- 

 mium diaphanum, Geramium striatum ; II. (1888). PLelminthora 

 divaricate Callithamnion brachiatum, Geramium tenuissimum, 

 Spyridia filamentosa, Delesseria Hypoglossum, Gatenella Opuntia, 

 Lomentaria reflexa, Ghondriopsis tenuissima, Bhodomela subfusca, 

 Dasya coccinea, Bostrychia scorpioides ; III. (1890). Griffithsia 

 barbata, Lomentaria Tidlifornis, Chrondriopsis dasyphylla, Plo- 

 camium coccineum, Phyllophora membranifolia ; IV. (1893). 

 Ghoreocolax polysiphonio3, Rarveyella mirabilis, Phyllophora 

 rubens, Cystoclonium purpurascens, Spha-'rococcus coronopifolius, 

 Gracilaria confervoides, Bhodymenia pahnata, Ehodym. palmetta, 

 Lomentaria articulata, Nitophyllum Gmelini, Delesseria alata, 

 Deless. ruscifolia, Hydrolapathum sanguineum, Bonnemaisonia 

 asparagoides, Odonthalia dentata, Ralarachnion ligulatum. 



Besides the spermatangia of the species given above and 

 figured by him, Mr. Buffham has furnished us with a descrip- 

 tion of the male organs (in a certain number of species), in 

 which the morphological type corresponds with those of some 

 of the forms illustrated. He succeeds perfectly in making us
