Facet counts and measurements indicate that growth in the holochroal eyes of Isotelus iowensis and Nileus vigilans is accomplished by addition of new facets at the base, probably during molting, and by increase in the size of the largest facets; the former is the dominant process. The rate of addition of facets appears to be non-uniform in many individuals.
