Description
Ostracods from several drowned terraces of Neogene age in the Hawaiian Islands, ranging in depth from 260 to 355 fathoms, resemble in part, Modern faunas of the Hawaiian and South Pacific Islands. Of the 26 species and 19 genera from the terraces, 18 species and three genera are new. Five recent species and new occurrences of Pacific ostracods that have previously been described are reported from Alijos Rocks, Clipperton Island, the Hawaiian Islands, and the Sahul Shelf in the East Indies. The new species are included for comparative purposes. Information about Pacific Ostracoda is not sufficient to allow precise ecological comparisons between living faunas and fossil assemblages. However, most of the described forms from the terraces occur living at depths less than 50 fathoms, and none have been found living at depths greater than 160 fathoms. Faunistic differences occur between the drowned terraces reflecting possible temporal and/or environmental differences between the sites of deposition.
