Abstract: A well-developed medusa of Atorella vanhoeffeni Bigelow, 1909 (Cnidaria, Scyphozoa, Coronatae) was collected on November 11, 1995, as the second record of this genus in Japanese waters. Based on this specimen, a description is provided along with photographs. A morphological comparison is made between the present species and Atorella japonica Kawaguti and Matsuno, 1981 from the Sea of Japan near Oki Island, Shimane Prefecture, Japan.
