The light spaces between the crossbands or blotches are wider than the dark markings. On the belly, the crescent-shaped markings on the ventrals tend to form two stripe-like series. The maximum recorded total length for this subspecies is 131 cm (51.5 inches). However, most adults are 56-102 cm (22-40 inches) in total length.
