Males grow to a maximum total length 575 millimetres (22.6 in), of which the tail is 120 millimetres (4.7 in) in length. Females reach a maximum total length of 1,045 millimetres (41.1 in), with a tail length of 165 millimetres (6.5 in).[4]
Scalation: dorsal scales in 23–25 longitudinal rows at midbody; first upper labial partially or completely fused to nasal; 9–13 upper labials, 1–2 rows of scales separate upper labials from the suboculars; 11–14 scales in a line between supraoculars; supraoculars rarely divided; temporal scales small, strongly keeled; ventral scales: males 153–174, females: 151–180; subcaudals: males 62–79, females 49–61, usually paired, occasionally unpaired shields present among paired series.[4]
