Geological investigations in Papua and New Guinea have largely been carried out by, or on behalf of, companies engaged in the search for oil. One hundred and fifty-six species of Foraminifera, referred to 58 genera, are recorded and illustrated; 35 species have been described as new. Where possible, species have been given their attribution as recorded in the collection of the Australasian Petroleum Company, Port Moresby, and the known stra!igraphical range within Papua and New Guinea is indicated. The genera Bolivinoides and Afrobolivina are considered to be synonyms of Bolivina, based on a comparison of the internal structure of the type species. The generic name Brizalina is used for species having the biserial chamber arrangement bf Bolivina, but lacking the basal chamber lobes. Species with a biserial to uniserial growth and lacking basal chamber lobes are referred to the genus Rectobolivina. In the genus Bulimina the 'second foramen' recorded in several species is considered to be formed by the toothplate 'cutting off' part of the septal foramen; it does not occur on the final chamber.
