Unpublished material originally identified by J.-M. Remy, as well as evaluation of his type material deposited in the Muséum national d'Histoire naturelle, Paris, has resulted in two new genera, Remyranina n. gen. and Planobranchia n. gen.; two new species, Liocarcinus heintzi n. sp. and Szaboa lamarei n. sp., and five new combinations, Remyranina ornata n. comb., Calappilia? gorodiskii n. comb., Mursia simplex n. comb., Planobranchia simplex n. comb., and Planobranchia laevis n. comb. These taxa include the first Oligocene record for the Matutidae, and the extinct genus Szaboa is re-diagnosed. The Remy collection, comprised primarily of fossils from France and equatorial Africa, consists of numerous Calappidae and Carpilioidea, especially abundant today in tropical environments, suggesting that at least for some taxa in these groups, environmental tolerances have changed little since the Eocene.
