Notice the somber hues on the body of this snake. Olive gray along its spine and dorsum, two pale stripes on the side, the scales under the chin momentarily yellowish, but the yellow does not continue onto the belly (as would be the case with a yellow-bellied racer), but instead turning to a pale, mottled blue-gray just beyond the neck. This darker, blue gray marks most of the remaining belly, but not at the boundary of the belly and the sides, where the belly coloration grades to a pale white. [...]
