niidclle feathors, almost wholly miit'onn diisky. A narrow wlii I o, supercil- 

 iary stripe, and beneath this a tniiisoeiilar stripe (about (MO to 0.15 

 wide), oceupyini;' lores and upi)er portion of anricnlars, similar in color 

 to thepileuin. Chin, throat, chest, and sides of head up to the brown 

 transocnlar stripe, iininacnhite, pure white; rest of lower parts dull, 

 blackish dusky, tijiged witli brown (especially on Hanks and upper 

 breast), and everywhere barred with white, these white bars rather 

 narrower and more tinged with brown on ui)per part of breast, the lat- 

 eral portions of which are less distinctly barre«l; thighs lifjht brown 

 with very indistinct narrow darker barsou inner side. Length (mounted 

 specimen), about 5.00; wing, 2.55; tail, 2.10; exposed culmen, 0.70; 

 bill from nostril, 0.48; depth at anterior end of nostril, 0.17 ; tarsus, 

 0.!)0." 



"This specimen, which is an adult in considerably worn plumage, 

 differs from the only other Colombian example that I have seen (No. 

 34095, U. S. Nat. Mus., S ad., Sta. Marta), and also from descriptions, 

 in having the entire breast barred with white, there being no uuiforin 

 black band or space between the barred portion and the pure white 

 chest; the upper parts are a much lighter and much duller brown, 

 but this may be due to the worn condition of the plumage. It is also 

 smaller, the Sta. Marta specimen measuring as follows: Length (skin), 

 6; wing, 2.75; tail, 2.20; exposed culmen, 0.70; bill from nostril, 0.52 ; 

 depth at anterior end of nostril, 0,20; tarsus, 0.95."
