The portion of the rostral scale which is visible from above is at least as long as its distance from the frontal. The rostral is wedged between the internasals, which are shorter than the prefrontals. The frontal is hexagonal, longer than broad, longer than its distance from the end of the snout, and shorter than the parietals. A large pentagonal occipital is seen, the point of which is wedged between the parietals. A small preocular and two small postoculars are present. There are seven upper labials, the second and third are in contact with the prefrontal, the third and fourth enter the eye, the fifth and sixth are largest and are in contact with the parietal. Two pairs of large chin shields occur, which are separated from each other on the median line by two series of small scales.
