a, b. 6. Mubuku Valley, E. Ruwenzori, 6000 ft., 15th & 22nd Jan. [Nos. 101, 

 123. R, E. B.) 



c. 6 . Mubuku Valley, E. Ruwenzori, 6000 ft., 1st Feb. [No. 137. R. E. D.} 



Iris dark brown or hazel ; bill brown or black ; feet brown or light brown. 



Specimens b and c are marked "breeding." 



[A few examples of Hartlaub's Ground-Robin were met with in the Toro district 

 and in the valleys on the east side of Ruwenzori up to 6000 ft. These birds were only 

 observed among the elephant-grass and were by no means common. Towards' evening 

 one occasionally saw one of them perched on the top of a tall grass- stem, giving vent to 

 a succession of loud clear whistles, and I once saw one near the ground, bobbing up 

 and down on a grass-stem and going through a kind of dance, with its tail spread 

 out like a fan; but I failed to ascertain the cause, as there was no other bird near it. 

 Perhaps it was only joy at having found an open space among the endless elephant- 

 grass.— R. B. W.}

 Iris reddish-brown ; upper mandible black, lower slate-grey ; feet slate-blue. 



This species has hitherto been recorded only from Cameroon and Fernando Po. 

 Mr. Alexander has kindly lent me the type of A. moori Alex., which appears to be 

 synonymous with A, poliothorax, and closely resembles the Ruwenzori specimens. They 

 differ, however, in the following points :• — 



Specimen a, which is obviously an immature bird, as is shown by its swollen gape, 

 has the general colour of the back deep orange-brown, rather than deep chestnut-brown, 

 and the crown is reddish-olive-brown instead of dark vandyke-brown. Specimen b, 

 a somewhat older bird, has the back of a more chestnut tint, much as in the type of 

 A. moori, but the crown is reddish-olive-brown as in specimen a. The underparts are 

 alike in all three specimens. 



[Two examples of this rare Robin-Chat were obtained by Mr. Gerald Legge in the 

 forest-zone of Ruwenzori at an elevation of from 7000 to 8000 ft. They were shot 

 while skulking along in the thick undergrowth. The species has a curiQus harsh 

 note. It was not met with either in the Congo or Mpanga Forests. — R. B. W.~\
