Distribution

USA: Florida; Caribbean Sea: St. Martin (Pilsbry & Sharp 1897); Barbados; Antigua; Honduras (Henderson 1920); Brazil: Amapá to Rio de Janeiro, including Fernando de Noronha Island (Penna 1972; Penna­Neme 1974; Scarabino 1975, 1985, 1994). Living 26 to 59 m (Penna­Neme 1974), shells down to 150 m.
