Short description

The head and neck are moderately thin. Cream, grey or pale brown cross-bands with paler interspaces are wider dorsally and taper on the sides. Incomplete secondary dark bands between the primary ones may be present, with dark-centered scales on the paler parts of the body. Head is pale, bandings on the tail. More obscure than those on the body and in older adults. Head shields are irregular and fragmented in adults. Those around the eye are raised posteriorly to form spines. Prefrontal scales absent.
