 CHIRIQUI WOOD WREN. 



Adult m<de. — Pilenm :uul hindneck sooty black, the t'eatliers (except 

 those of lateral portions) usually* more or less distinctly tipped with 

 sooty brown or sooty grayish, these brownish or sooty grayish tips 

 sometimes so broad as to conceal the underlying black, thus giving 

 the median portion of the pileiun (broadly) a uniform sooty gra}' or 

 brownish color; back, scapulars, rump, and upper tail-coverts plain 

 dark rufous-brown or chestnut-brown (])etween deep nnunmy brown 

 and burnt-umber); tail duller brown, more or less distinctly barretl 

 with black: wings similar in color to back, etc., narrowly and rather 

 indistincth' barred with black; a narrow superciliary stripe of broad 

 white streaks; a broad postocular stripe of l)lack, involving upper 

 portion of auricular region; sides of head below eyi^ and l)lack post- 

 ocular stripe broadly streaked with black and whit(\ in nearly e<|ual 

 amount (the black sometimes predominating); sides of neck black, 

 broadly streaked with white; chin and throat white, streaked with ])lack 

 or l)lackish slate; chest and breast plain slate-gray, the lower portion 

 of the latter sometimes showing paler tips to feathers; abdonuMi very 

 pale gray or grayish white, the feathers tipped with pale tawny, buffy, 

 or whitish, and more or less distinctly barred with slate-gray;'' flanks, 



^'In a specimen (National Museum collection, no. 119898, adult female) from El 

 Achiote, Costa Rica, in fresh plumage, the pileum is entirely l)lack without trace of 

 brown or sooty tips to the feathers. 



*'In the specimen from El Achiote, Costa Rica, previously referred to, not only the 

 abdomen, but the median portion of the breast also is very distinctly, but irregularly 

 barred with black. This specimen, although a female, is decidely larger than the 

 males from Costa Rica (one from Jimdnez, the other from the Volcan de Irazu, and 

 may represent a different form. All the Costa Rican specimens examined (only 

 four in number, however), have the pileum decidedly blacker tiian the majority of 

 CIiiri(iui examples.
