There seem to be two recognizable races of this bird : — 



1. A. R. RUBiGiNosA (Rupp.). From the White Nile and 

 Abyssinia to inland Glerman and British East Africa. 



Synonyms of this are : 



Crateropus rufescens Heugl. J. f . O. 1863, p. 24 : Upper 

 Bahr el Abiad. 



Argya rufula Heugl. Orn. N.O.-Afr. iv. Appendix, 

 p. cccxiii. 



Argya rnbiginosa emini Reichw. O. M. 1907, p. 30 : 

 Unyamwesi, G.E.A. 



We can see no difference between birds from the White 

 Nile, Abyssinia, and the Masai country. 



2. A. R. HEUGLINI. 



Argya heuglini Sharpe, Cat. Bds. B. M. vii. 1883, p. 391 : 

 Zanzibar. 



From southern Somaliland to the coasts of British and 

 German East Africa. 



A much richer coloured bird, especially the underside, 

 which is all one shade of rich rufous, and does not get paler 

 on the belly. 



Synonyms are : Argya saturata Sharpe, P. Z. S. 1895, 

 p. 488 : Zanzibar. And possibly 



Argya sharpii Grant & Reid, Ibis, 1901, p. 662 : Shebeli. 



There has been much confusion about the names and 

 races of these two birds. Riippell first described the first 

 race from Shoa, Later, in 1863, Heuglin described the 

 same bird, which he believed to be a difi'erent form, under 

 the name Crateropus rufescens from the upper White Nile ; 

 subsequently, finding the specific name rufescens was already 

 preoccupied by the use of it for au Indian species by Blyth,
