Adult male in breedmrf-jylumaije. Head, nape, and kind neck white ; 

 lores, the feathers round the eye, ear-coverts, sides of the neck, back, 

 and the whole of the underparts except the tips of the under tail- 

 coverts and part of the tail black ; scapulars black, the outer webs 

 of the outer ones white, joining onto the white upper and median 

 wing-coverts ; rest of the wing dark brown ; lower rump, belly, and 

 under tail-coverts white : longest upper tail-coverts black, tipped 

 with white, rest white ; two central tail-feathers dark brown, the 

 two next with more or less white on the outer web ; four out- 

 side tail-feathers on each side white, generally one or more and some- 

 times all with a dark brown terminal patch on each web, occasionally 

 becoming coufiiient ; under surface of wing dark brown. Bill, legs, 

 feet, and claws black. "Wings with the third, fourth, and fifth pri- 

 maries nearly equal and longest, second primary intermediate in 

 length between the sixth and seventh, bastard primary 1-25 to 0-9 

 inch. Length of wing 4-3 to 4-05 inches, tail 2-9 to 2-6, culmen 

 0-85 to 0-76, tarsus 1-25 to 1-15. 



The female in breeding-plumage has the head, nape, rump, tail, 

 and wings as in the male, except that the dark brown of the tail 

 and wings is not so dark ; all the rest of the parts are grey, shading 

 into nearly white on the centre of the belly. The change which is 

 produced by the autumn moult, which appears to take place in 

 February and March, is unimportant. Toung in first plumaye 

 appear to be iinknown ; but hirds of the year of both sexes have 

 the rump, upper and under tail-coverts, and tail as in the adult, the 

 whole of the rest of the plumage being brown. After the second 

 moidt the adult plumage is assiimed, except that the belly of the 

 male is white, the fully adult plumage with black belly apparently 

 not being assumed until the third moult is complete. 



Burchell's Chat has only been obtained from Bcnguela and Damara 

 Laud, where it is supposed to be a resident.
