General color of body, hath above and below, deep chocolate brown or olive brown, with a very conspicuous, sharply marked, white or very pale yellow median dorsal stripe extending whole length of body,and gradually enlarging on head to form a broad, pear-shaped whitish marking, often two thirds to three fourths as wide as head. Marking is broadest, and often slightly emarginate, near tip of snout, gradually becoming narrower through about half the length of the head, where it merges into the narrow dorsal stripe which continues throughout the body. Most individuals show a faint reddish line extending from each cephalic furrow backward along lateral margin of body. Cephalic furrows often slightly paler, and rosy; intestinal region inclining toward an olive brown shade. Colors and marking of body well retained after preservation.
