Drysdalia mastersii, also known as Masters's snake, is a species of venomous snake endemic to southern Australia. The specific epithet mastersii honours Australian zoologist George Masters who collected specimens for Gerard Krefft.
The snake grows to an average of about 40 cm in length. The upper body is light brown to dark grey, with a pale band over the nape and a white stripe extending from the upper lip to the neck.[1]
The species is viviparous, with an average litter size of three. Its diet consists mainly of lizards.[1]
The species’ distribution extends eastwards from near Esperance in Western Australia into coastal and subcoastal South Australia, as well as in south-eastern South Australia and western Victoria. It inhabits heathland, grassland and mallee habitats on sandy and limestone soils.[1] The type locality is the Flinders Ranges of South Australia.[2]
