Soft parts: Iris reddish brown; bill black (yellow at angle of 

 mouth in juvenal birds) ; feet and claws brown (slightly darker in 

 the juvenal birds). 



I agree with Sclater *^^ and van Someren ^^ that Zedlitz's races hil- 

 gerti and erlangeri can not be maintained. If they were valid, the 

 Dire Daoua and Sadi Malka specimens would, on geographic grounds, 

 be erlangen^ and those from southern Shoa and northern Kenya Col- 

 ony would probably be hilgerti, but I find no size or color differences 

 between them. I can not account for Zedlitz's results, although it must 

 be admitted I have seen no topotypical material of either of his races. 

 Also, it may be that the birds of northern Kenya Colony and ex- 

 treme southern Shoa are not supposed to be hilgerti^ but are (as I 

 find them) indistinguishable from simplex. This would account for 

 the fact that van Someren and I both find no differences in our re- 

 spective series, although van Someren had birds from the lower 

 reaches of the Juba Kiver, which must be considered hilgerti if that 

 form be recognized. Gyldenstolpe ^^ considers hilgerti a valid race 

 but unfortunately gives no discussion. 



The size variations of the present series are shown in table 34.
