Schuchert and Dunbar (1934) described from a small reef in the Long Point Formation (Middle Ordovician) of western Newfoundland a massive colonial organism, 3 feet in diameter, which the authors referred to the genus Monotrypa Nicholson. Because this size seemed excessive for a bryozoan I began a study, through the courtesy of the Peabody Museum of colonial forms from the above-mentioned reef. Although no species of Monotrypa has yet turned up in my investigation, a new species of Diplotrypa Nicholson has been identified and is described herein as Diplotrypa schucherti.
