white, are tipped with black, as in the preceding young birds. 

 The specimen is in full moult, and the new greater coverts 

 and inner secondaries are black with broad grey margins. 

 The shoulder-patch is decidedly whiter than in the previously 

 mentioned grey bird.

The newly moulted feathers are black in comparison with 

 the brown shade to which they ultimately bleach.

The male has not got the entirely white outer tail-feather ; 

 otherwise it is grey and resembles specimen e (March 4). 

 In confirmation of the grey plumage being consequent upon 

 the blackish dress, there are still some black feathers 

 remaining on the abdomen.

A very remarkable specimen which has not yet quite com- 

 pleted its moult. It is black both above and below, with black 

 under tail-coverts, a few only of which are fringed with 

 white. The shoulder-patch is pure white, with black bases 

 to a few of the feathers. The crown is somewhat browner 

 than the back and forms a faint cap. The outer tail-feathers 

 are not pure white, but have black tips. 



m. <$ ad. Deelfontein, April 23, 1902. 



An adult bird in full grey plumage with the two outer 

 tail-feathers white. The shoulder-patch is very slightly paltr 

 grey than the back. The inner median coverts are rather 

 more hoary. The rump is white, but the upper tail-coverts 

 arc blackish, more or less washed with slaty grey. The under- 

 tail-coverts are slaty grey, the longer being blackish. 



//. <$ ad. Deelfontein, May 7, 1902. 



A grey bird, similar to the foregoing, but darker and in- 

 clining more to slate-colour, with the bases of the feathers and 

 the centre of most of them blackish, apparently foreshadowing 

 a blackening of the feather without a direct moult. The 

 shoulder-patch is grey and the outer tail-feathers are white 

 as in the preceding specimen, while the upper and under 

 tail-coverts are also similar. Most of these grey males have
