CUKSORIUS.

Burchell's Courser is only found in South Africa, where it frequents the Karroo and 

 the high veldt, but does not descend to the lowlands near the coast. It is not uncommon 

 in the Cape Colony. I have an example from Bechuana-Land, and it is very abundant up 

 country in the Transvaal, and near Newcastle, in the extreme north of Natal (Feilden, 

 Zoologist, 1882, p. 340). It is not found north of the Tropic of Capricorn. Andersson 

 did not meet with it in Damara-Land, nor is it recorded by Buckley from the Matebele 

 country. 



It is probably nearest related to C. senegalensis and C. coromandelicus, which agree 

 with it in having, when adult, a nearly black patch on the belly. Fortunately this character 

 is correlated with grey axillaries, a feature probably of much earlier origin, as it appears in 

 young in first plumage as well as in the adult.
