GEOKICHLA. 551 



mm. Legs, feet, and claws flesh-color. Wing, 108 to 102; tail, 61 to 

 53; culmen, 19.5 to 18; tarsus, 29 to 28. The adult plumage of the 

 sexes appears to be alike, nor is it known that any important change takes 

 place by abrasion. 



Young in first plumage appear to have the whole of the upper parts 

 dull chestnut, each feather having a pale shaft and obscure pale center; 

 the white bars on the wings are suffused with chestnut, and the black on 

 the under parts is confined to two moustachial lines on the cheeks, the 

 rest being dull chestnut. This plumage is immediately molted to the 

 adult plumage in the first autumn, except that certain birds, which I take 

 to be females, have the slate-gray of the upper parts replaced by dark 

 olive-brown." (Seebolim.)
