Sixty-eight species of Foraminifera, and one species of problematical organism, are described from the Haslam, Qualicum, and Trent River formations of Vancouver Island (Santonian - Early Campanian). A new species is described for each of the genera Hagenowina, Cyclogyra, Lenticulina and Bullopora?, and a new species Mammilla hemispherica is erected for the problematical organism. High values of faunal diversity and calcareous benthic/agglutinated ratio are treated as indicating relatively deep neritic water, whereas low values indicate shallow neritic water. On this basis the Foraminifera are listed in order of increasing water-depth, and a paleogeographic reconstruction is made which indicates that, where the mountainous core of Vancouver Island now exists, there was at this time a landmass with a seaway in the region of the Strait of Georgia, and that two headlands projected northward from this landmass into the seaway — thus causing the threefold geographic division of the sediments into Haslam, Qualicum, and Trent River formations.
