A classification of the phylum Sipuncula
Bulletin of the British Museum of Natural History (Zoology)
A classification of the phylum Sipuncula is adopted following the analysis of Cutler & Gibbs (1985) and comprises two classes, four orders and six families. This replaces the earlier classification of Stephen & Edmonds (1972) which was based on four families only. The diagnostic characters are reviewed. Seventeen genera are redefined, one new subgenus is described and twelve other subgenera are recognised.
