Dr. Reichenow (op. cit.) recognises four subspecies of 
L. sulphureipectus. I have carefully examined the series in 
the British Museum, in which all but the Angola form 
(L. modestus Bocage) are well represented. Of this latter 
there is only cne specimen. The typical form from West 
Africa with its wide yellow forehead and marked yellow 
eyebrow-siripe seems to be fairly separable from L. chryso- 
gaster (Swains.), which is said to range from Senegambia 
to Abyssinia and thence southwards to Lake Nyasa. To this 
form the present specimen must be referred. I cannot, 
however, distinguish LZ. chrysogaster from the South- 
African ZL. similis Smith, adult birds from Abyssinia being 
indistinguishable from those from the Cape. Mr. Neumann’s 
remarks on this subject are not borne out by the specimens 
before me.
