not distinguishable from P. familiaris. P. f. omoensis is 

 barely recognisable as a subspecies. 



172. PHCENICUaUS mesoleucus. 



Phomicurus bonapartei (Miill.) and P. mesoleucus (H. & E.) ; 

 Reich, iii. p. 781 (1905). 



Ruticilla phtenicurus bonapartii Neumann, J. f. O. 1906, 

 p. 294. 



Among the series of Ehrenberg's Redstart procured near 

 Lake Zwai in January and February, we find specimens 

 referable to P. bonapartei. An examination of the skins in 

 the British Museum from Asia Minor and Arabia seems to 

 show clearly that the distinctions founded on the greyer or 

 blacker colour of the back are of no importance. 



173. COSSYPHA SEMIRUFA. 



Cossyplia semirufa semirufa Riipp. ; Neumann, J. f. O.

Cossyplia semirufa saturatior Neumann, /. c. 



Typical examples of the Abyssinian Robin-Chat were 

 met with in the neighbourhood of Addis Abbaba, ranging 

 up to 10,000 feet on Mount Mergeta near Addis Alara. It 

 was also obtained in Jimma and from Kullo, the birds from 

 that locality having been separated (in my opinion quite 

 unnecessarily) by Prof. Neumann as C. s. saturatior. The 

 typical form was also found in Arussi to the east of Lake 

 Zwai, while further east its place was taken by the following 

 subspecies : — 



174. CoSSYPHA SEMIRUFA DONALDSONI. 



Cossypha semirufa donaldsoni Neumann, J. f. O. 1906, 

 p. 283. 



Cossypha semirufa Ogilvie-Grant, Ibis, 1904, p. 270 [part. 

 Harrar]. 



A single example of this rather larger form, with grey 

 wings and the middle pair of tail-feathers black, was obtained 

 at Bourka on the 9th of February, when Zaphiro was 

 apparently on his way to Harrar.
