Two specimens (131.5 and 147.0 mm in standard length) of the Gelatinous Blindfish Aphyonus gelatinosus Günther, 1878, collected from southern Japan (Kumano Sea and near the Tori Island, part of the Izu Island chain), were found among preserved specimens held by the Department of Natural Science, Faculty of Science, Kochi University, Kochi, Japan and National Museum of Nature and Science, Tsukuba, Japan. Aphyonus gelatinosus is recognizable in having only a single pelvic fin ray, high numbers of dorsal fin rays (92–118) and caudal vertebrae (46–55), few long gill rakers (3–4), and short predorsal length (26.5–30.5% SL). This species and genus is known from the Pacific Ocean, but not from the north Pacific including Japanese waters. Thus, these specimens are a new record of both the genus Aphyonus and A. gelatinosus for Japan.
