Seventeen species and subspecies of planktonic Foraminifera are recorded from approximately 1,000 feet of Senonian Upper Chalk from Culver Cliff, Isle of Wight. Four species, Planomalina ehrenbergi, P. rowei, Schackoina cushmani, and Globotruncana culverensis, are described as new. Planktonic-benthonic ratios suggest a neritic or upper bathyal environment for the deposition of most of the Upper Chalk. There is indication of a shallowing of the Upper Cretaceous sea at the beginning of the Belemnitella mucronata Zone.
