specimens shot on the highlands in the winter and spring 

 are more rufous, and have more or less broad rufous 

 margins to the tail-feathers, quiUs, and wing-coverts. 

 The greater portion of the outer tail-feathers and a por- 

 tion of the next pair are whitish in colour, the centres of 

 the latter being usually dusky. The coloration of the 

 underparts also varies slightly. In some birds the breast 

 is distinctly spotted ; in others there is not a trace of 

 spots. Mr. Tristram, who has kindly examined my 

 specimens, considers that aU the varieties belong to one 

 species, and I am quite disposed to agree. There is great 

 variation in dimensions. I give those of all the specimens 

 collected, five in number : — 



Anseba . 

 Senafe 



„ . 3-55 2-5 105 575 0-56 Young, very pale. 



It is just possible that the last specimen, which is entirely 

 without spots on the breast, should be referred to ^. 

 campestris, L., but I am disposed to consider it a young 

 specimen of A. sordidus. 



Anthus sordidus keeps much to rocky hiU-sides, where 

 there is but little bush. It was common near Senafe, 

 and equally so on the more barren hills bordering the 

 Anseba valley. It sometimes perches on trees.
