Definition of Motley?

Can anyone explain just what the motley pattern is? I've looked at dozens of pictures and I'm just not getting it! Thanks.

I am going to quote The Corn Snake Manual by Bill & Kathy Love:
"'Motley' is an inherited anomaly that tends to elongate and join the dorsal blotches together. They can range in appearance from a ladder-like pattern of fused or partially fused blotched to a complete and perfectly even stripe down the entire dorsal surface of the snake. The results can be extremely variable! It's not unusual for the pattern to form stretches of partial stripes that meld into normal or partially fused blotches at random areas across the back. The pattern disruption also affects the side blotches, basically erasing or absorbing them, or at least reducing them to scattered remnants of spots and streaks laterally. This mutation also exerts a secondary influence in which the black ventral checkerboarding pattern is completely, or nearly completely, lost. Some specimens will have various shades of reds and oranges present on the belly; others are plain white with a light peppering."

Thanks! I think I've got it!
