Painted turtles were examined from Kentucky and Tennessee. Two zones of intergradation were established on the basis of several characters. These characters were the degree of disalignment of the carapacial seams, the presence of a dark plastral mark, the width of the light borders of the seam of the second lateral lamina, and the width of the dorsal stripe. A zone of intergradation occurs in eastern Tennessee between the subspecies Chrysemys picta picta and C. p. marginata. A second zone occurs in western Kentucky and northwestern Tennessee between C. p. marginata and C. p. dorsalis. The zoogeography of these zones is discussed.
