An objective index to the literature is given for Genus Candona (Ostracoda) in North America, through 1975, combined with a subjective review pertaining to validity and synonymy of species. Pre-Quaternary species are not considered. There are 102 entries, including 97 names. Taxonomy of Candona has not surpassed the initial descriptive level. Specific diagnosis can be based on valve morphology alone. There are about 45 known valid nearctic species, most of which are clearly confined to the nearctic realm; supposed holarctic ranges of other species are questioned.
