While visiting the Bellairs Research Institute at Barbados during one of his collecting trips to the West Indies, Dr. P. WAGENAAR HUMMELINCK took two large samples of surfacial floor sediments of the sea west of Barbados. These samples have been trusted to the author for foraminiferal research. The excursion on which the material has been collected, aboard the research vessel “Diadema”, had been organised by the Director of the Bellairs Institute, Dr. JOHN B. LEWIS. The results add to our knowledge of the benthonic communities of Barbados’ west coast (see also LEWIS, 1965, and MACINTYRE, 1967).
