The Shiranui Sea is a large bay located to the south of the Ariake Sea, western Kyushu. Its malacofauna is reviewed in terms of biogeographic relationships with the Ariake Sea. The Shiranui Sea can be categorized by malacofauna into three groups : 1) the northern area defined by species common to the Ariake Sea, 2) the transitional area between north and south, and 3) the southern area under the influence of warm-current open-sea water. This biogeographic division is also supported by the distribution of fish species and Arthropoda. The inner bay area of the Ariake Sea and the northern Siranui Sea belong to the same biogeographic zone characterized by the Ariake Sea principal species group, which is divided into I ) the temperate-zone group, 2) the temperate to subtropical-zone group, and 3) the temperate to tropical-zone group, In the southern Shiranui Sea, a tropical molluscan community exists in muddy tidal flat, and its composition and origin are discussed. Faunal research of the Shiranui Sea is in need of further detailed investigation, especially from the viewpoint of the conservation of nature.
