The southern adder averages 20 cm in length (with a maximum length of 40 cm). It has two white bands beneath and between the eye. It has horned tufts above the eyes. The southern adder is greyish-brown in colour, with dark brown patterning down the centre.

Distribution
The southern adder is found in three separate subpopulations on the southwestern coastal margins of the Western Cape. Previously, a fourth subpopulation in Cape Town is thought to be locally extinct. The northern subpopulation is found from West Coast National Park to approximately 20 km north of Cape Town. The southeastern subpopulation is found near Hermanus and near De Hoop Nature Reserve.
