Hartert ^^ writes that wings of West African birds measure 95-100, 

 those of northeastern Africa 100-108 millimeters. The female col- 

 lected by Mearns at Chaffa, Ethiopia, has a wing length of 97 milli- 

 meters, how^ever. Gyldenstolpe ^ writes that eight birds from Eritrea 

 have wings varying from 9G.2-106.2 millimeters in length, so that 

 the ChafFa bird is not the only exception to Hartert's measurements. 



The material examined by me is unfortunately either from extreme 

 ■western parts of west Africa or from east Africa, with very little 

 from intermediate areas. Consequently I can not contribute any- 

 thing definite to the task of delimiting the ranges of the two forms. 

 As far as the material goes, it upholds the conclusions reached by 

 Sclater.2 The eastern limits of the typical form are by no means 

 clear. Sclater writes that alhicollis occurs east to the Uele and 

 Ituri districts of the Belgian Congo, but both Gyldenstolpe ^ and 

 Sassi ^ call birds from the eastern Ituri district simply Aerops alhi- 

 collis and either state or suggest that subspecies are unrecognizable.
