Brit. Mus. xxi. 1893, p. 419: Xiger, cannot possibly be a race 

 of this species, because we have an abundance of specimens 

 of S. semitorquata from the same district. It is, of course, a 

 race of S. decip/ens, as pointed out by Zedlitz, J. f. O. 1910, 

 p. 343. 



Secondly, we do not think *S'. s. minor of Erlauger is a 

 synonym of S. s. semitoi'i/uata, or, rather, we have no proof 

 that it is, as we iiave not a single specimen from southern 

 Somaliland, Those from the coast of Biitish East Africa, 

 which one would expect to be nearest to it, are certainly of 

 very small size, wings 175 mm. and under. Thirdly, owing 

 to paucity of material from the type-locality, we should not 

 like to be certain whether the typical race is really separable 

 from the West African form known as >S'. s. erytkrophrys 

 (Swains.). At present we must regard it as distinct, but 

 there seem to us no tangible differences between the Lado 

 bird and Roseires specimens, though, accoi-ding to Zedlitz 

 (J. f. O. 191 L, p. 614), S. s. Intermedius of Erlanger from 

 S. Abyssinia is synoi'vmous with <S'. s. erythroplirys, and the 

 Lado bird should be of this form, while the Roseires birds 

 should be nearer the typical race. 



There are two Arabian specimens in the Museum which 

 appear rather distinct, as their backs are lighter brown and 

 their undersides considerably more bluish and less i)inky. 

 They may prove to be separable when more material is 

 obtained.

S. deeipiens is not unlike S. semitorquata, but is somewhat 

 smaller, a good deal greyer on the underside, lighter on the
