lected by Mr. Bates having tlie back greyish-black, wot deep 

 black. He obtained examples of both forms, irrespective 

 of sex or season. Shaipe arrived at practically a similar 

 conclusion (c/. 'Ibis,' 1908, p. 124). 



Saxicola salax (Vei-r.) . 



Mr. Bates has sent several examples, both male and 

 female, of this species from Akonolinga, Nyong River, 

 eastern Cameroon. The average wing- measurement of six 

 males is 68 mm. 



The average wing-measurement of thirty-four specimens 

 of Saxicola salaw from Kilimanjaro, Lake George, Ruweii- 

 zori, Uganda, Kikuyu Ravine, Kenia, and Lake Naivasha 

 is 71 mm. 



The average of twelve male specimens from the Peak of 

 Cameroon and Fernando Po is 73*5 mm. These represent the 

 slightly larger race named Pratincola jmllidigula Reichenow. 



Mr. ]?annerman, 'Ibis,' 1915, p. 498, has kept up this 

 name, and has given certain wing-measurements in support, 

 but from carefully taken wing-measurements we find the 

 average is 73*5 mm. in twelve male specimens from the 

 Peak of Cameroon and Fernando Po.

Since the notes in the liuwenzori Report were published 

 in 1910, the British Museum has received, through the 

 kindness of Mr. L. M. Seth-Smith, a female example of 

 this species from Mpumu, Uganda. In this bird the wing, 

 which has been injured by shot, measures at least 7Q mm. 

 (= 3 inches), whereas in the type of A', albigularis Sharpe, 

 from Fantee, the wing measures 68 mm. (=:2'7 inches). 

 That the former species is synonymous with the latter still 

 requires confirmation. 



Another male example was procured at Bitye, River Ja, 

 on the 29th of August, 1911; the first sent by Mr. Bates
