are ferruginous, but some of them are very slightly and 

 irregularly edged with blackish brown on the outer webs 

 towards the tips. 



The male speeimen differs from the female in having the 

 crown of the head of a somewhat darker grey, and also in 

 the rectrices (other than the central pair) showing more 

 blackish brown on the outer webs, which is especially the 

 case with the external pair. — J. H. G.]

 8 inches, bill (from gape) i|, tarsus 1, wing 3f, tail 3|.

[The plumage of these specimens agrees with the descrip- 

 tion given under the head of P. nigricans in the first edition 

 of Mr. Layard^s work. In the female killed on the 18th of 

 May, which had nearly moulted, the head is decidedly black ; 

 in the male killed on the 11th of January the plumage is 

 w orn and faded, and the head, though black, is slightly tinged 

 with brown ; but in neither specimen does the colour of tlie 

 head agree with the description given in the second edition 

 of Mr. Layard^s book under the head of P. capensis. —
