NEW FOSSIL CRINOIDS FROM JAMAICA

Fossil crinoids are poorly known from the Antillean islands. To the fi ve taxa of fossil crinoid previously recorded from Jamaica are added t wo further species of isocrinid, both based on pluriocolumnals and lef t in open nomenclature. Austinocrinus n. sp. is the first Lower Cretac eous echinoderm to be described from Jamaica and represents the earlie st report of this genus. It is the only fossil stalked crinoid from Ja maica to occur in a shallow-water deposit. Isselicrinus cubensis? (Val ette, 1926) forms part of an allochthonous assemblage in the Lower Eoc ene Port Maria shell bed. Isselicrinus cubensis was originally describ ed from Cuba, and the genus also occurs in Haiti, Mexico, and elsewher e.
