The zooecia in question have zooecial aperture distinctly transversely elongated and about twice as long as that of ordinary zooecia. Frontal avicularia (c) with triangular mandible which is simply pointed at end without curving ; they are much smaller than vicarious avicularia. Vicarious avicularia (d) are provided with large triangular mandible, being pointed and slightly curved at apex. The above type specimen was obtained from off the Misaki Marine Station. Depth unknown. A somewhat smaller specimen, which may be regarded to be specifically identical with the type, is to hand from Kagoshima Gulf. This differs not inconsiderably from the type in Fig. Fig. 7. Adeonella hexangitlaris, n.
