Empty shells of a tropical cephalopod Nautilus pompilius Linnaeus, 1758 (Nautilida: Nautilidae) are known to be drifted to the coasts of the Japanese Archipelago, but it has been believed that no record was present on the Pacific coasts of the Tohoku District, northern Honshu, where is distant from the Kuroshio and the Tsushima Current. However, a drifted shell of the species has been handed down since 1812 (Bunka 9 in the Edo Period) in the Suzuki Family, Shichigahama-machi, Miyagi-gun, Miyagi Prefecture. According to a tradition in the Suzukis, the shell appeared as attached to a sea turtle from off Shichigahama, and the history of the drift and preservation was recorded in old literature. Sincethen, the Suzukis have called the shell " Fuketsu-no-kai " and carefully preserved it as their heirloom. The name Fuketsu-no-kai is a probable corruption of " Kuketsu-no-kai " that is one of the Japanese synonyms of the species in the Edo Period. In Niigata Prefecture, the drifted shells of the present species are called Kuketsu-nokai and revered. Therefore, this folklore is assumed to have been introduced into the Pacifi ccoast of Miyagi Prefecture by religious people. The present shell is thought to be a highly important specimen in the contexts of natural history, historiography and folkloristics: the present shell is a very rare case of the drift of the species into the Pacific coast of the Tohoku District; the detailed story of the drift can be documented by old literature; the present shell is a good example showing an old Japanese folklore of worship of the species.

Seeds of Macropsychanthus (Fabaceae) drifted on the coasts of Japanese islands were classified to seven species based on about 700 seed collections. The identified species were M.comosus (G.Mey.) L.P.Queitoz & Snak, M.ferrugineus Merr., M.hexander (Ralph) L.P.Queiroz & Snak, M.javanicus (Benth.) L.P.Queiroz & Snak, M.umbrinus (Elmer) L.P.Queiroz & Snak, M.wilsonii Standl.) L.P.Queiroz & Snak, and an unknown species(M. " mable " tentatively named). Most frequent seeds are M.hexander, which were about 80% of all drift seeds of Macropsychanthus. The following frequent species were M.wilsonii (5%), M.comosus (4%), M.ferrugineus (4%) and M.javanicus (3%). M.umbrinus and M. " mable " were rarely drifted and about 1%, respectively.The characters of their seeds were described.

和歌山県田辺湾に異例の数のタガヤサンミナシの貝殻が漂着した.それらの貝殻模様の新鮮さを基準に3段階に分類し,漂着の原因を考察した.新鮮な貝殻を多く含む異例の数のタガヤサンミナシの漂着は, 2010年12月-2011年2月の厳寒と,採取した時期に接近した台風の影響が大きいことが示唆された.また,極めて稀に漂着した生きたタガヤサンミナシ1個体を飼育し,摂食行動を確認した.
