Dr. Reichenow (Voég. Afr. i. pp. 627, 629) has altered 
the names of the two species which have been recognised by 
me (cf. ‘ Ibis,’ 1900, pp. 154-157) as S. micrura Riipp. and 
S. brachyura Lafr.; the former he calls S. lewcopsis (Reich.), 
the latter S. micrura Rupp. I have again gone closely into 
the question and am still convinced that the white eye- 
browed white-throated bird, the S. leuwcops:s (Reich.), is also 
S. micrura Riipp. Riippell’s figure and description of the 
bird clearly shew that the eyebrow-stripe and throat are 
white, and this appears to me to settle the question. 
According to Dr. Reichenow, S. drachyura is confined to 
West Africa, but, as has already been pointed out, examples 
from the Gold Coast differ in no way from Abyssinian 
specimens, and Bonaparte states that Lafresnaye’s type was 
procured in “ Sennaar” and not in Senegambia. 
Dr. Reichenow, who has examined Riippell’s types of 
S. micrura iu Frankfurt, states that two forms are mixed up 
under that name, but, as already stated, Riippell’s description 
and figure leave no room for doubt as to which bird he 
referred to, though he was certainly wrong in giving Kordofan 
as the locality where the species was found. ‘lhe rufous- 
eyebrowed and rufous-throated bird must therefore stand 
as 8. brachyura Lafr. and not as S. micrura, S. leucopsis 
(Reich.) being a synonym of the latter.
