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 hr.ck 

 and sides of the individuals more commonly obtained. Tnis variety is represented by Wagler,* 

 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.
