Twelve new species of two genera Smenospongia and Cacospongia (Demospongia: Dictyoceratida: Thorectidae) are described from Gageodo Island and Ulleungdo Island, Korea. Of these, ten new species of the Smenospongia are distinguished from the other nine reported species of the genus by the skeletal structure and sponge colour. Primary fibres of the genus Smenospongia are mostly dense, dark colour, and invisible inside of fibres, but they are mostly cored detritus and echinated with spicules. Especially, the end of primary fibres at the surface shows densely cored with spicules. All these new species changed the colour. Two new species of the genus Cacospongia are compared with nine other reported species. In skeletal structure, primary fibres of the genus Cacospongia are light colour, visible inside and more heavily cored with spicules and sands. The skeleton of this genus has large meshes. The colour of the genus Cacospongia does not change.

A large number of Demospongiate have been collected from 18 localities in Cheju Island and its adjacent waters during the period from 1970 to 1991. The identified Demospongiae consist of 67 species, 40 genera and 30 families. Among them 11 species were new to Koera; Oxeostilon fernaldi, Microciona gradalis, Tedania ignis, Haliclona koremella, Adocia neens, Callyspongia variabilis, Suberites axinelloides, Anthosigmella raromicrosclera, Epipolasis kushimotoensis, Acanthella insignia, and Spongosorites salimonensis.

Ten new species of two families (Suberitidae and Polymastidae) are described from Korea. Six new species in Suberitidae: Plicatellopsis ramosa n. sp., Pseudosuberites anheungensis n. sp. P. youngilensis n. sp., Suberites hwasunensis n. sp., S. chujaensis n. sp. and S. rugosa n. sp. are compared with other similar reported species. All new species differ from previously reported species in morphology, texture, color, skeletal structure, and spicule type. Four new species in Polymastidae: Polymastia fistula n. sp., P. sasuensis n. sp., P. viridis n. sp., and Weberella haengwonensis n. sp. are different from previously reported species in the growth form of papillaes and fistules, color and spicule types. For example, Weberella haengwonensis is similar to Weberella verrucosa in shape, but differs based on surface papillaes and spicule sizes.
