A review of the literature added another 37 species reliably recorded from the archipelago, bringing the total muricid fauna of Fiji to 95 species. Twenty-fi ve species, including 14 shared with Fiji, are reported from Tonga. Bouchetia n. gen. is described for Poirieria (Paziella) vaubanensis Houart, 1986, originally described from New Caledonia and now recorded from Fiji. Conchatalos spinula n. sp. and Prototyphis gracilis n. sp. are described from Fiji; Murexsul merlei n. sp. is described from Fiji and Tonga. Attiliosa caledonica (Jousseaume, 1881), formerly treated as a synonym or subspecies of Attiliosa nodulifera (Sowerby, 1841), is recognized as a valid species, as both species co-occur in Fiji without intermediates. Pascula ambonensis Houart, 1996, Tritonidea lefevreiana Tapparone Canefri, 1880 and Pentadactylus paucimaculatus Sowerby, 1903 are reclassifi ed in Cytharomorula Kuroda, 1953. RÉSUMÉ Gastéropodes Muricidae des îles Fidji et Tonga. Cinquante-huit espèces de Muricidae (Coralliophilinae exceptés), dont 3 nouvelles, ont été récoltées au cours de récentes expéditions aux îles Fidji. Un examen critique de la littérature indique la présence crédible dans cet archipel de 37 espèces additionnelles, ce qui porte à 95 le nombre d’espèces de Muricidae maintenant connues de Fidji.
