The colours of the male and female are nearly if not quite alike. 
A variety of this species is occasionally procured in Southern Africa, on which only very few 
if any of the yellow and liver brown spots exist, which a r " described as occurring on the back 
and sides of the individuals more commonly obtained. This variety is represented by W agleiy* 
and all the specimens of it which I have seen had the chin and throat coloured as represented 
in his plate. 
Both are found within the boundaries of the Cape Colony; but the one which is most 
profusely variegated is by far the most common. The former I have only seen in damp 
shady situations, abundantly coated with brushwood ; the latter sometimes in similar situations, 
but more frequently in dry, arid plains, furnished with a considerable quantity of underwood. 
In whatever situations they are discovered, they always immediately seek concealment, and 
generally attempt it by burrowing under decayed leaves, or loose earth. The range of this 
species is extensive, and specimens were obtained by the expedition party, even as far north as 
the Tropic of Capricorn.
