Dorsally, H. ravergieri is tan or grayish, with a series of dark rhomboidal spots or crossbars, alternating with smaller spots on the sides. The spots usually become confluent posteriorly, and appear as dark stripes on the tail. There is a diagonal dark streak below the eye, and a similar subparallel streak from the back of the eye to the corner of the mouth. Ventrally, it is whitish or covered with blackish dots.
The weakly keeled dorsal scales are arranged in 21 rows. The ventrals, which are obtusely angulate laterally, number 190-222; the anal is divided; and the subcaudals, which are paired, are 75–101.
Adults may attain 133 cm (4 ft 4 in) in total length, with a tail 32 cm (12+1⁄2 in) long.[2]
