A comparative study of the Jaton species in East Atlantic waters, pp 11-36, figs 1-15, tabel 1, map 1, pls 1-18, by Frank Nolf & Steve Hubrecht.

Keywords: Jaton, Muricidae, Gastropoda, Mollusca, W Africa, junior synonyms.

Abstract: The description of a few doubtful new species in the past years has lead us to undertake a review of all the Jaton species living in the East Atlantic waters of West Africa. Four species are recognised as valid: Jaton decussatus (Gmelin, 1791), Jaton hemitripterus (Lamarck, 1816), Jaton sinespina Vermeij & Houart, 1996 and i flavidus (Jousseaume, 1874). Only the latter shows a constant appearance and can easily be separated from the other Jaton species. Jaton westsahariensis Franchi, 2007 and Jaton rikae Petuch & Berschauer, 2019 are treated as junior synonyms. After studying dozens of specimens we have to ascertain that an important part of the material shows a transition between the extreme forms used in the original descriptions.
