a lighter dorsal stripe, three scales in width. A stripe of the same 

 color on the outer row of scales. On each side of the dorsal stripe 

 two rows of minute brown spots are sometimes present. The spots are

 Just behind the occipitals is a salmon-colored blotch, and behind the 

 angle of the mouth is another blotch of the same color. The top of

Habits.— This snake is not as abundant as the preceding

 found a slug in the stomach of one of these snakes.
