Morphologic as well as morphometric changes occur in the character of fresh lunar craters at a diameter range of about 10-20 km. The continuous size/morphology sequence advocated by Smith and Sanchez (1973) is sustained by their data only for craters between 10-20 km and about 100 km in diameter. The cumulative-morphology index, and the frequency-of-occurrence of wall terraces, central peaks, flat floors, and 'swirl texture' (Smith and Sanchez, 1973) support the existence of a morphologic transition at a crater diameter of 10-20 km, rather than a continuous gradation in shape within craters between 4 and 150 km in diameter.
