This well-marked species, which I have named in honour 

 of my respected friend and first instructor in South American 

 ornithology, Dr. P. L. Sclater, in the shape of the bill and in 

 other structural characters is a typical Thripadedes, while 

 in coloration it combines the characters of that genus with 

 those of several species of Automolus. The coloration of the 

 throat is that of Thripadedes agreeing also with that of 

 A. melanorhynchus (Tsch.), the feathers being pale cinnamon- 

 brown with well-marked lateral margins of black. The 

 coloration of the breast, belly, and under tail- coverts is also 

 nearly the same as that of A. melanorhynchus. On the other 

 hand, the upperparts show nearly the same coloration' as 

 A. rufóbrunneus (Lawr.) ex Costa Rica, the feathers of the 

 pileum being but very slightly striated with hairlike pale 

 shaf times, while they are otherwise olive-brown margined 

 broadly with black, just as in that species. The back is only 

 a little darker, the outside of the wings much darker, more 

 brownish, less olivaceous. The rmnp and the tail are much 

 darker, more chestnut than rufous-brown. The bill is strong 

 as in Thripadedes and a little longer than in Thr. flamm ulatus. 



In its nearly uniform coloration Thr.virgatieeps Lawr. from 

 Ecuador, seems to agree with Thr. sdateri, but the former is 

 said to have the a front crown, cheeks and hind-neck 

 blackish-brown, the feathers of all these parts with broad 

 shaft-stripes, those of the crown and hind neck greyish- white, 

 the others of a pale rufous."
