The spatial distribution of craters 8 km diameter on an area of Callisto are compared with that of a lunar highlands area from which craters are removed to produce the Callisto size/frequency distribution. Craters in the lunar area are mapped and classified according to degradational type using the five-fold LPL scheme where Class 1 is the freshest and Class 5 the most degraded. The size/frequency distribution are determined and compared with the Callisto area. Craters are removed according to the stage of degradation. Its crater population is basically a production population deficient in large craters relative to that of the terrestrial planets. This indicates that the population of impacting objects responsible for the period of heavy bombardment in the inner solar system was different from that at Jupiter, and probably had a different origin as well.
