Recent ostracode fauna from seven localities (Alligator Harbor, Ochlockonee Bay, Tampa Bay, Crane Key, Bahia Honda, Molasses Reef and Key Largo Dry Docks) is described and illustrated. Seventy species, distributed over 37 genera occur in the bays and the inner neritic zone. Three genera, Megacythere (type species: Megacythere robusta Puri, n. sp.), Neocaudites (type species: Neocaudites nevianii Puri, n. sp.) and Reticulocythereis (type species: Reticulocythereis floridana Puri, n. sp.) and twenty-two species (Actinocythereis subquadrata Puri, n. sp., and twenty-two species (Actinocythereis subquadrata Puri, n. sp., Acuticythereis tuberculata Puri, n. sp., Bairdia shulerae Puri, n. sp., Bradleya hornibrooki Puri, n. sp., Bythocypris laeva Puri, n. sp., Caudites angulata Puri, n. sp., Caudites howei Puri, n. sp., Cyprideis floridana Puri, n. sp., Cytheropteron howei Puri, n. sp., Cytherelloidea sarsi Puri, n. sp., Hemicytherura cranekeyensis Puri, n. sp., Hulingsina sulcata Puri, n. sp., Kangarina bradyi Puri, n. sp., Leptocythere cranekeyensis Puri, n. sp., Leptocythere yoni Puri, n. sp., Loxoconcha postdorsoalata Puri, n. sp., Loxoconcha ochlockoneensis Puri, n. sp., Megacythere robusta Puri, n. sp., Neocaudites nevianii Puri, n. sp., Platella mülleri(sic) Puri, n. sp., Puriana floridana Puri, n. sp., Reticulocythereis floridana Puri, n. sp.) are described as new.
