the upper t;iil-coverts are entirely obsolete and the brown baiuis on the 

 wings are much paler than the color of the back. VVing-coverts distinctly 

 batided with black. Concealed markings of rump feathers almost obsolete. 

 Below slightly darker than adult with wavy lines across the throat, breast, 

 and belly, produced by a very narrow terminal band to the feather^. 

 Flanks and crissum dark Isabella color without bands. Female similar. 



As the birds grow older the wavy lines below grow fainter. The cris- 

 sum becomes lighter and is banded with dusky. The dark liaiuliiig on the 

 wing-coverts grows fainter while that on the upper lail-coverts becomes 

 distinct. 



No. 4577 and No. 4S79 have the tlanks very distinctly barred with dusky, 

 the brown bands on the wings are much paler than the brown of the back, 

 and are but little wider than the black bands. The wing-coverts are dis- 

 tinctly barred. 



Below I present a table of measurements of the specimens in the col- 

 lection of the Museo Nacional, together with four from my own private 

 collection.
