Excerpt from A Further Study of Pattern Dimorphism in the California King SnakeThe ringed and striped phases do not differ essentially in head pattern, they are likewise similar in body color. The light marks in either may vary from white to buff, and the dark from red - brown through chocolate - brown almost to black. The color contrast is usually more accentuated in the young than in adults.The ringed pattern consists Of light cross - rings separated by dark, there being from 22 to 40 of these rings on the body and 6 to 10 on the tail (fig. The relative widths of the two sets of rings vary considerably, but usually the dark rings, where they cross the mid dorsal line, are 3 or 4 times as wide as the light. Sometimes the light rings engage. Only a single scale, but more Often they cover about 2 scales, end to end, where they cross the middle Of the back. Laterally, as the light rings approach the ventrum, they widen at the expense Of the dark, so that as they cross the belly the widths of the light and dark rings are approximately equal, or the light may be wider.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
