Eight new ostracode species and two new varieties from the Bahia beds of Brazil, and one new species from the Todilto limestone member of the Morrison formation of New Mexico are described and illustrated. Four additional species from the Bahia beds are discussed. A new subgenus of Cypridea Bosquet, here named Paracypridea, is introduced, and Roth's genus Pseudocypridina is redefined as a subgenus of Cypridea. The evidence suggests that the major part of the subsurface Bahia beds in the Bahia embayment is Upper Jurassic (Purbeck), and there is reason to believe that the uppermost Bahia may be early Lower Cretaceous (Wealden). The Todilto limestone member of the Morrison contains a species related to Metacypris whitei Jones of the Upper Jurassic Morrison formation, but the more typical Morrison Ostracoda are not known in the Todilto.
