a. cJ ad. Shebeli, Aug. 27, 1894. Iris straw-yellow. 



This I take to be the true A. ruhiginosa of Eiippell. The 

 bird usually called A. ruhiginosa by African authorities is that 

 which I have called A. heuglini (Cat. B. vii. p. 391), as the 

 name of rufescens proposed for it had been preoccupied by Blyth. 

 I had not noticed that Heuglin himself had discovered his mistake 

 and in his ' Appendix ' to the ' Ornithologie Xordost-Afrika's ' 

 (iv. p. cccxii) renamed the species A. ritfula, which name has been 

 adopted by Dr. Eeichenow (Yog. Deutsch-Ost-Afr. p. 219), who 

 unearthed Heuglin's identification. On looking over our series, 

 however, I find that there are three species of these rufous- 

 coloured Argyas, which may be characterized as follows : — 



a. Lores grey or dusky. 



a'. Larger ; dark brown above ; forehead dark grey, 

 extending to beyond the line of the eyes ; hind- 

 neck and mantle also dark brown with dark shaft- 

 lines quite distinct : wing 3"8 inches rubiginosa. (Sboa 



and Somali.) 

 b'. Smaller ; light brown above ; a narrow frontal line 

 of grey ; hind-neck light brown, but the dark 

 shaft-lines not distinct, except on the forehead ; 



wing 3-35 inches rufula. (Equatorial 



Africa.) 

 h. Lores vinaceous rufous, like the sides of the face and 



the under surface of the body saturata. (E.Africa.) 



Hence arises a curious confusion of synonymy. Heuglin duly 

 noticed the difference between A. rubiginosa and A. rufescens, but 

 as the latter name was preoccupied, I proposed to call it^. heuglini, 

 but at the same time I described the bird from Zanzibar, which 

 now proves to be distinct from A. rufula (i. e., A. rifescens, Heugl., 

 nee Blyth). 



The name of the Zanzibar bird will therefore be 



Aegta satueata, n. sp. 



Argga rufula, auct., ex Africa Orientali (nee Heuglin). 



Argya heuglini, Sharpe, Cat. vii. p. 391 (pt. descr. nee syn.). 



We have now several specimens of A. rufula, Heugl., and of 

 A. saturata in the Museum collection, and the rufous lores and 

 sides of face in the latter species are very pronounced.
