A new deep-water pleurotomarian gastropod from the vicinity of Guadeloupe, Lesser Antilles, is described as Perotrochus pyramus. This is the seventh species discovered in the western Atlantic, and the second to be shown to have a very low, broad turbiniform shell during intermediate stages of growth, becoming relatively higher as growth proceeds. Various aspects of the shell, sculpture, and progressive changes in shape are illustrated.
