A collection of octocorals taken by Prof. P.L.G. Benoit and Prof. Bouillon, and another collection made by Prof. Bouillon and Prof. Tursch, appeared to contain thirty two species. Two of them are new, viz. Sarcophyton turchi sp. N. and Capnella bouilloni sp. N. Two species have not been reported from the Seychelles before: Cladiella australis (MacFadyen, 1936) and Sinularia mayi Lüttschwager, 1915. In addition to a description of the two new species, a redescription of Cladiella australis (MacFadyen, 1936), Sinularia notanda Tixier-Durivault, 1966, and Capnella parva Light, 1913, is given.
