The specimens from Nairobi and its environs, Naiwasha 

 Molo and Loodiani are exactly like each other, with dark, brownish 

 black heads but are dark-brown (without any black), v. S o - 

 m er en (Nov. Zool, XXV, 1918, p. 286) calls his specimens from 

 West Elgon: P. barhatus minor Heugl. but my specimens from 

 the eastern slopes of Elgon do not agree at all with the de- 

 scription Reichenow (Vog. Afr. Ill, p. 422) gives nor with 

 the measurements given by M e a r n s (Smithson. Misc. Coll. 

 vol. 56, No. 20, p. 9). According to the latter the measurements 

 of the wing are 91.7 mm. for d'd' and 88.3 mm. for 99- The 

 extremely little variation in the colour of the feathers of the 

 head is probably only a difference due to the time of 

 the year, inasmuch as the plumage of the Elgon birds is much 

 abraded and they were mostly shot 1 — 3 months later than 

 those from the Kikuyu country and southwards, the majority of 

 which were, in fact, in moult or had already assumed the new 

 dress. The lower wing-coverts of minor are also said — accor- 

 ding to Reichenow— to be greyish brown, but in these 

 specimens they are of the same colour as in those from the 

 south, i. e, greyish white. 



But if the minor occurring on the White Nile and in the 

 country east of Victoria Nyauza, fayi inhabits the western side 

 of Elgon, it is not impossible that the one appearing on the 

 eastern slopes of Elgon is an intermediate between these two.
