discovered by D^Orbigny, whose specimens were obtained in 

 the Province of Yungas. Mr. Buckley also procured examples 

 at Tilotilo, in the same province, which are now in our col- 

 lection. Besides these, Mr. Sclater has a skin, and there is 

 a similar one in the University Museum at Cambridge, which 

 formed part of a collection that was sold in London in 1852, 

 and which was believed to have been formed in Bolivia ; but 

 no certain information on this point transpired, nor is the 

 collector's name known. 



8. brunneiceps has no near allies, except S. castaneocapilla 

 of the highlands of British Guiana.

The single specimen of this species obtained by Schom- 

 burgk in the Roraima Mountains of British Guiana still re- 

 mains unique. This specimen, through the tindness of Dr. 

 Peters, I am now able to compare with the Bolivian S. brunnei- 

 ceps — the species to which it is most nearly allied. The chief 

 difference between the two consists in the colour of the back, 

 which in S. brunneiceps is ashy, with a large median olivaceous 

 patch, while in S. castaneocapilla the back is nearly uniform 

 brown, with a scarcely perceptible tinge of olive. The feathers 

 of the sides of the head of the specimen of 8. castaneocapilla 

 are somewhat worn ; but I can trace white feathers surround- 

 ing the eye, but not the white loral streak shown in 8. brun- 

 neiceps. There is also a difference in the amount of white in 

 the lateral tail-feathers ; these in 8. brunneiceps are white 

 almost to the base, whilst in 8. castaneocapilla the white is 

 confined on the outer feather to the terminal half.
