Four species of Onoba H. Adams et A. Adams, 1852 are reported from the Barents Sea and adjacent waters of Arctic Basin and White Sea: O. aculeus (Gould, 1841), O. semicostata (Montagu, 1803), O. leptalea (Verrill, 1884) and O. improcera Waren, 1996. Onoba karica Golikov, 1986 is considered as a synonym of O. leptalea. Both O. mighelsi (Stimpson, 1851) and Alvania jeffreysi (Waller, 1864) were erroneously recorded from the Russian waters by previous authors.
