The White-Crowned Snake (Cacophis harriettae) is a small, mildly venomous elapid native to eastern Australia. Its most distinctive feature, and the source of its common name, is a pale cream to white band or patch crossing the top of the head, contrasting sharply with the darker body coloration.
Coloration & pattern
The body is typically a uniform dark grey to blackish-brown or reddish-brown along the back, without strong blotching or banding, giving it a smooth, plain appearance. The belly is pale cream to yellowish, sometimes with darker mottling near the tail. The pale head band or crown patch is the standout field mark, usually appearing as a distinct light band across the nape or crown region just behind the eyes.
Head, eyes & scales
The head is small and only slightly distinct from the neck, typical of small burrowing elapids. Eyes are small with round pupils, as in all Australian elapids. Scales are smooth and glossy, giving the snake a sleek appearance. The pale crown marking is the primary diagnostic feature visible on the head.
Size & body shape
This is a small snake, with adults typically reaching only 30–50 cm (12–20 in) in length. The body is slender and cylindrical, typical of small fossorial to semi-fossorial elapids adapted to life under leaf litter and debris.
Range & habitat where you'll see it
The White-Crowned Snake is found in coastal and near-coastal eastern Queensland and northeastern New South Wales, favoring moist forest, woodland, and rainforest margins. It is a secretive, nocturnal species most often found sheltering under logs, rocks, leaf litter, or debris.
How to tell it apart from look-alikes
The pale crown band across the head reliably distinguishes it from similarly small, dark-bodied elapids such as other crowned snake species, though close relatives like the dwarf crowned snake also show pale head markings and require careful comparison of head band shape and extent. Its small size, plain dark body, and secretive habits under litter separate it from larger, more boldly patterned elapids in the same region.
