INTRODUCTION Of the bottom material collected by the Snellius-Expedition 78 samples contained Foraminifera. Many of these samples were extremely small, since they were gathered by means of piston core samplers; some were larger, as they were collected by means of a dredge; others were samples in shallow water at beaches or reefs. A l l samples were fixed in formaldehyde, so that after the 40 years they remained in store before they were studied, rests of protoplasma were seldom preserved. The numerous plankton samples, preserved in formaldehyde or in alcohol, did note contain planktonic Foraminifera; obviously the small amount of CaC03 in the samples caused the dissolution of the tests. The planktonic Foraminifera are not described here, as planktonic forms of the Pacific Ocean were already studied by Parker (1962) and by Todd (1965). Planktonic specimens from several of the localities are preserved in cardboard slides, but, as they do not belong to the bottom fauna, they were not considered ecologically. Several slides are preserved containing the planktonic fauna of a sample as a whole.
