In studying the systematics of this tinker bird I have examined a 

 series of 30 specimens representing all three races, and my conclu- 

 sions agree wdth those reached by C. H. B. Grant ^° and by Sclater.^^ 

 The geographic forms are as f ollow^s : 



1. P. pysillvs pnslllus. — Eastern Cape Province (west as far as 

 Grahamstown and Algoa Bay), Pondoland, and Xatal to the coastal 

 districts of Zululand and of Swaziland. This race has yellow streaks 

 on the occiput, nape, and interscapulars, is pale olive green on the 

 underparts, the throat yellower, less olivaceous, and is larger than 

 either of the other forms, the wing length in the specimens examined 

 being GO-Gl millimeters. 



2. P. pusilhis ajfinls. — From southern Somaliland, northern Kenya 

 Colony and northwestern Uganda (Moroto and Turkwell districts), 

 south through Kenya Colony to northern Tanganyika Territorj^ from 

 the Ikoma region to Dar es Salaam. This subspecies has white 

 streaks on the occiput, nape, and interscapulars; is much paler, not 

 olivaceous, below than the typical race (sometimes almost whitish 

 with a faint yellowish buffy wash), and is smaller; wings 50-58 

 millimeters. 



3. P. pusiUus wopiiglalls. — Eritrea, Bogosland, and all of Ethi- 

 opia and also in northern (that is, French and British) Somaliland; 

 doubtfully in the Sudan. Sclater and Mackworth-Praed ^' note that
