Four new species of Carazziella are described from North and South America: C. hobsonae from Florida and Texas, C. calafia from central California, C. carrascoi from Chile and C. patagonica from Argentina. Carazziella citrona (Hartman, 1941), the type-species, is redescribed from the California type-collection and C. reishi (Woodwick, 1964) from the Marshall Islands is redescribed from the holotype and from new materials from Indonesia and Johnston Atoll. Relationships of the American species with counterparts in Australasia are discussed along with a consideration of the peculiar gizzard-like structure found in some species of Carazziella and Polydora.
