The races of P. »ie</m bave been discussed at length by 

 Neumann, Nov. Zool. 1903, pp. 383-385, and by Claude 

 Grant, Ibis, 1915, pp. 258-260. Tiie two specimens from 

 Kordofan are interesting as very little material has been 

 obtained from there since Riippell's time. At first sight 

 these birds appear to differ markedly from Sennar or 

 Bahr el Gbazal birds, but on closer inspection there is 

 nothing that could not be accounted for by their undoubtedly 

 worn condition. The yellow of the (oreliead is very pale 

 indeed, and the rump is a good deal more blue than in other 

 Sudan birds, as are also the feathers of the breast, while 

 the back is greyer. All this, however, might be due to worn 

 plumage, and while we ourselves suspect that more material 

 will prove them to be a distinct race, at present we prefer 

 to unite them with the rest of the Sudanese examples.

This very interesting bird is, in our opinion, in all pro- 

 bability the young ofc' a race of P.flavifrons, as suggested by 

 Reichenow and others. Neumann, however, in the J. f. O. 

 for 1904, p. 376, and again in the Nov. Zool. xv. p. 382, 

 strongly maintains that it is nothing of the sort. 



This example, which appears to be only the second known, 

 is an almost exact replica of the type, but it lacks the one 

 or two yellow feathers in the forehead possessed by that 

 bird. We have no young examples of P. flavifrons to com- 

 pare it with, but Neumann, who has examined it, says it 

 is markedly distinct in many respects. We conclude,
