Zusammenfassung:Nassarius levis sp. nov. is described from Canopus Bank, off Ceará, Northeast Brazil, based on shell morphology. It differs from other Brazilian species of the genus in having a more elongate shell, with a weakly developed parietal shield and a notably smooth surface. This last trait has not yet been described among the Western Atlantic Nassarius, but it is common to other congeners from the Eastern Atlantic, such as Nassarius elatus (Gould, 1845) and the Indo-Pacific, such as Nassarius excellens (Kuroda & Habe, 1961).Nassarius levis sp. nov. é descrita para o banco de Canopus, estado do Ceará, Brasil com base na morfologia da concha. Difere das outras espécies locais por apresentar uma concha mais alongada, com um escudo parietal pouco desenvolvido e uma superfície notavelmente lisa. Essa última característica ainda não foi descrita entre as espécies de Nassarius do Atlântico oeste, mas é comum a outros congêneres do Atlântico leste, como Nassarius elatus (Gould, 1845) e Indo-Pacífico, como Nassarius excellens (Kuroda & Habe, 1961).
