A comparative study of the various type specimens of species of the genus Cryptopecten Dall, Bartsch & Rehder, 1938, as well as additional material makes a provisional revision of the recent species of the genus in the Indo-Pacific possible. Based on this material five species are recognized, viz, Cryptopecten bernardi (Philippi, 1851), C. nux (Reeve, 1853), C. vesiculosus (Dunker, 1877), C. guendolenae (Melvill, 1888), and C. bullatus (Dautzenberg & Bavay, 1912). A lectotype is designated for C. nux (Reeve, 1853), and a type-locality for C. bernardi (Philippi, 1851).
