312 Distribution of Ostracoda in the Neogene of central Haiti

The ostracode fauna of the Neogene deposits from the the Central Plateau and the Artibonite Valley of Haiti is described from more that 400 samples. More than 100 ostracode species are recognized, of which 60 are illustrated. Three brackish-water species are described as new: Cyprideis n. sp.?, Perissocytheridea cahobensis, and Perissocytheridea ? haitensis. Central Haiti formed a single depositional basin during the Neogene in which penecontemporaneous environments ranged from continental to deep marine. The sea regressed in a southeasterly direction; marine deposition ceased in the northeast near the end of the early Miocene and persisted in the west until the Pliocene. The stratigraphic and paleobathymetric distributions of species of the genera Krithe and Costa are discussed.
