Brown.—Papers.—Report on the botanical collections made by Dr. W. A. Cunnington in lakes Nyasa, Tanganyiku and the Victoria Nyanza, 1904–5: Dr. A. B. Rendte. Dc, Cunnington spent about three weeks on and about Lake Nyasa, nearly nine months at Lake Tanganyika, and less than a fortnight on the west of the Victoria Nyanza. His object was to make as complete a collection as possible Of the plants and animals, especially from Lake Tanganyika, with the view of solving the “Tanganyika problerm”—whether the fauna and flora of this lake indicate a former marine connection. The flowering plants, fern allies, and Characeæ, numbering about forty-five species, were, for the most part, well-known and widely-distributed forms, such as Najas marina, species of Potamogeton, Pistia Stratiotes, Ceratophyllusn demersum, Myriofrhyllum spicatum, Jussiaea repens, Trapa natans, and Chara zeylanica. with others restricted to tropical or subtropical Africa, such as Ottelia, Boottia sccrbra, and species of Utricularia. In no case was there any suggestion of marine conditions, either past or present, in the represerittives of the flora.
