 in having the upper parts olive-grey instead of olive-green, 

 and the under surface slate-grey tinged with ochreous-bulf 

 on the abdomen and under tail- coverts, instead of pale ash- 

 grey on the throat and breast, white on the abdomen, and 

 isabelline-bufl' on the vent and under tail-coverts. 



The type, which is in the British Museum, was collected 

 by Capt. Philip Gosse, R.A.M.C, who accompanied Mr. E. 

 A. Fitzgerald on his expedition to the ''Highest Andes," and 

 in whose honour the species is named.
