The body is in various shades of pale brown, grey, greyish-brown, greyish-green or pale olive-green, slightly paler on the lower parts of the side; dark brown dorsal blotches or crossbands, more or less faint, 2 to 3 scales wide on each side; these dorsal blotches may be divided on the vertebral line and their halves slightly set off each from the other; a lateral series of irregular, dark grey or dark brown spots on the 4th, 5th or 6th dorsal scale rows, numerous, more or less aligned as a very discontinuous stripe, especially of 4th DSR, or widely scattered on any of these scale rows; a series of dark brown spots on scales of the 1st and lower part of those of the 2nd scale rows, usually widely separated; in some specimens a cream, narrow ventrolateral stripes extends on tip of ventrals and the lower part of the first dorsal scale row, dissected by brown spots of the ventrolateral series. The tail is as the body, with faint darker crossbars; posterior quarter of tail darker grey, pinkish-gray or greyish-green, with dark crossbars; tip uniformly dark.
