The collection of scalpellids from the Muséum national d’Histoire naturelle, studied by Gruvel, are reviewed, and their type specimens redescribed, including their appendages. Euscalpellum renei (Gruvel, 1902), Gruvelialepas pilsbryi (Gruvel, 1911), Catherinum recurvitergum (Gruvel, 1900), Arcoscalpellum atlanticum (Gruvel, 1900), Teloscalpellum luteum (Gruvel, 1900), Verum hoeki (Gruvel, 1901), Weltnerium bouvieri (Gruvel, 1906) and Ornatoscalpellum vanhoeffeni (Gruvel, 1907) are considered valid species. The following synonyms are recognized: Smilium longirostrum (Gruvel, 1900) (= Smilium acutum [Hoek, 1883]), Scalpellum edwardsii Gruvel, 1900 (= Neoscalpellum debile [Aurivillius, 1898]), Scalpellum patagonicum Gruvel, 1900 (= Ornatoscalpellum gibberum [Aurivillius, 1892]), Scalpellum striatum Gruvel, 1900, Arcoscalpellum curvatum (Gruvel, 1900) and Amigdoscalpellum talismani (Gruvel, 1900) (= Amigdoscalpellum rigidum [Aurivillius, 1898]), Scalpellum alatum Gruvel, 1900 (= Arcoscalpellum michelottianum [Seguenza, 1876]), Weltnerium weltneri (Gruvel, 1907) (= Weltnerium bouvieri [Gruvel, 1906]). The samples considered as Scalpellum gigas Hoek, 1883 (Trianguloscalpellum Zevina, 1978) by Gruvel from deep-water stations from Azores (Talisman Expedition 1883) are indeed Trianguloscalpellum ovale (Hoek, 1883). Arcoscalpellum crenulatum Foster & Buckeridge, 1995 is considered synonym of A. atlanticum (Gruvel, 1900).
