This report is a survey of the micropaleontology and stratigraphy of Upper Cretaceous rocks in the Ponce-Coamo area, south-central Puerto Rico. Planktonic foraminifera and radiolaria are utilized for the zonation of these rocks. Upper Cretaceous planktonics useful in zonation are illustrated. One new species of Praeglobotruncana and two new subspecies are described and illustrated.
