Smith, which came from Great Namaqualand, may prove to be equally 
valid.

This giant lizard makes its home in trees or amongst rocks, but is 
a great wanderer and, unlike the water-leguaan, seldom stays long in 
one place. When attacked it takes refuge in holes or in trees, or even 
in water. It feeds on insects or birds' eggs, ravaging hen-roosts when 
available, and is said to kill and devour smaller lizards and snakes.
