The SYLLIDAE of Japan are named with 77 species and 7 subspecies in 20 genera, 5 subgenera and 4 subfamilies; 2 others in 2 genera are not determined specifically. One new genus, 1 new ubgenus, 31 new species or subspecies and 5 new combinations are given. 21 species or subspecies are new to Japanese waters. One genus, Geminosyllis is erected from SYLLINAE and one new subgenus, Regulatus is named in Autolytus. 46 species or subspecies, 53.4%, are currently known only from Japan, 40 others are known also from other areas

The genus Boccardia (Polychaeta: Spionidae) associated with mollusc shells on the south coast of South Africa

Three species of Boccardia (B. polybranchia, B. pseudonatrix and B. proboscidea) were associated with mollusc shells on the south and south-east coasts of South Africa. Boccardia polybranchia was widely distributed along the coast and falls within the known distribution range of this species. Comparisons with material from other, international, locations showed that some specimens have been misidentified. No characters could be found to characterize distinct species for different regions within the range of B. polybranchia, as currently recognized. Boccardia pseudonatrix was found only at the most eastern site, increasing its known distribution range. Boccardia proboscidea, a non-indigenous species, was found only on abalone farms and was most abundant in the west
