L. simonii is flesh-colored, and may attain a total length (including tail) of about 20 cm (about 8 inches). The
dorsal scales are arranged in 20 rows around the body. The snout is very prominent and pointed, with a sharp cutting edge, below which are located the nostrils. The head shields are granulated. The
rostral is very large, and both the portion visible from above and the portion visible from below are longer than broad. The nasal cleft extends from the first upper
labial to the nostril, which is close to the rostral. The
preocular is as large as the ocular, but much smaller than the nasal, in contact with the second and third upper labials. The eye is not distinguishable. The
prefrontal and the supraoculars are larger than the body scales. There are four upper labials. The diameter of body goes 57 to 60 times in the total length. The tail is slightly longer than broad, without a terminal spine. ==Habitat==
