PLEISTOCENE ECHINOID (ECHINODERMATA) FAUNA FROM SOUTHEAST JAMAICA

A previously undocumented echinoid fauna occurs in the terrigenous cla stic sedimentary sequence of the Old Pera Beds (Lower Pleistocene) and the overlying Port Morant Formation (Upper Pleistocene) at Old Pera, parish of St. Thomas, southeast Jamaica. The fauna is comprised of com plete tests (particularly from two horizons in the Port Morant Formati on), test fragments, and radioles, and includes: Cidaris (Tretocidaris ) bartletti (A. Agassiz), Eucidaris tribuloides (Lamarck); diadematoid indet. gen. and sp.; Echinometra viridis A. Agassiz; Echinometra? sp. ; Clypeaster rosaceus (Linne); a juvenile C. subdepressus? (Gray); mel litid indet. gen. and sp.; clypeasteroid sp.; Schizaster doederleini C hesher, Meoma ventricosa (Lamarck); and irregular indet. gen. and sp. Schizaster doederleini is still extant in the Caribbean, but is not kn own to live in Jamaican waters. Schizaster doederleini and Meoma ventr icosa are the first nominal spatangoids to be reported from the Jamaic an Pleistocene.
