These Mearns' descriptions are based on resp. 5, 3 and 

 3 specimens. 



H. R. H. Prince Vilhelm's collection contains 6 spe- 

 cimens from the foot of Donya Sabuk which geographically 

 must belong to F. s. kapitensis. In the possession of this 

 museum are also two specimens from Kilimanjaro and one 

 from the Meru mountain, collected by Y. Sjöstedt, and of 

 these at least the first ought to belong to F. s. maranensis. 

 Finally I have myself collected a couple of specimens at 

 Escarpment which locality from a zoogeographical point of 

 view might be regarded as belonging to the Kenia terri- 

 tory. These Jatter specimens should thus be F. s. keniensis. 



If the characteristics at these specimens are considered 

 and compared, we will arrive at the following result, 



The crown is in the bird from Kilimanjaro »bister» \- in 

 the birds from Donya Sabuk it varies from »hair brown» to 

 »bister», in the birds from Escarpment is is »bister» or dar- 

 ker. The feathers of the back and scapulars have in the 

 Kilimanjaro birds a broad central (subapical) band of dark 

 chestnut, finely mottled with black (more coarsely in one of 

 them and in the bird from the Meru mountain), otherwise 

 these feathers are dark brown, edged with grey, and some 

 are speckled outside the central band. The birds from Donya 

 Sabuk vary a great deal, even in fresh plumage, with regard 



^ According to Ridgeway's nomenclature.
