Summary A range of species of the genus Lacuna have been numerically described in terms of the geometry of their shells. Species are uniquely distinguishable on this basis. Interspecific affinities and relationships defined here agree with those suggested by conventional classification, by general external appearance, and by presumed ecological pressures associated with zonation. Geometrical analysis may prove an accurate systematic aid at the specific or varietal level.
