Three species of pedunculate barnacles (Cirripedia, Thoracica) are recorded from the upper Lower Miocene Higashibessho Formation in Toyama Prefecture, Japan. Arcoscalpellum s.l. hamurorum, a new species of Scalpellidae represents the fourth record for the genus from the Miocene of Japan. The occurrence of Lepas kuwayamai Karasawa, Tanaka, and Okumura (Lepadidae) extends the known geologic range for the species to the late Early Miocene. Scalpellidae genus and species indeterminate is known from too few plates to permit more confident identification.
