" Iris light brown, feet and bill black." 



This bird is practically identical with the specimens in the 

 Tring Museum. The species was hitherto known only from 

 N.W. Ecuador, where Mr. Rosenberg a,nd his collectors obtained 

 three examples at Cachabi (500 ft.), Paramba (3500 ft.), and Rio 

 Sapayo (450 ft.). 



A. nigricauda is nearly allied to the group of A. riibiginosus 

 from Central America, but may easily be distinguished by its dull 

 blackish (instead of bright chestnut rufous) tail, less rufous wings, 

 darker ferruginous foreneck, dull brownish olive belly, etc., etc.

This series agrees perfectly with two specimens from Western 

 Ecuador (Carondelet, Paramba) in the Mvmich Museum, The 

 upper part of the head is nearly uniform olive-brown with 

 obsolete dusky edges to the feathers ; the back wholly unstriped, 

 rufescent brown ; the upper wing-coverts and outer webs of the 

 remiges are deep russet-brown ; the breast and abdomen dull 

 light olivaceous, the chest but indistinctly mottled with buffy, 

 etc. etc.
