Scales bordered in black which gives a cross-hatch pattern to the body, more intense along the midline of the side and sometimes resembles a series of X's along the body, The sides with 6 - 12 vertical bars, more conspicuous on the urosome and the intensity varies according to the geographical region of the population.
