of the Genus Setopliaga. 
discovered by D^Orbigny, whose specimens were obtained in 
the Province of Ynngas. Mr. Buckley also procured examples 
at Tilotilo^ in the same province, which are now in our col¬ 
lection. I 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.

The single specimen of this species obtained by Schom- 
burgk in the Boraima Mountains of British Guiana still re¬ 
mains unique. This specimen, through the kindness of Dr. 
Peters, I am now able to compare with the Bolivian B. hrunnei- 
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 8. brunneiceps is ashy, with a large median olivaceous 
patch, while in B. 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 B. castaneocapilla 
are somewhat worn; but I can trace white feathers surround¬ 
ing the eye, but not the white loral streak shown in B. brun¬ 
neiceps. There is also a difference in the amount of white in 
the lateral tail-feathers; these in B. brunneiceps are white 
almost to the base, whilst in B. castaneocapilla the white is 
confined on the outer feather to the terminal half.
