CHiRiaxri WOOD wren. 



Adult male. — Pileiim and hindneck sootj^ black, the feathers (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 pileum (broadly) a uniform sooty gray or 

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

 dai-k rufous-brown or chestnut-brown (between deep mummy brown 

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

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

 indistinctly barred with black; a narrow superciliary stripe of broad 

 white streaks; a broad postocular stripe of black, involving upper 

 portion of auricular region; sides of head below eye and black post- 

 ocular stripe broadly streaked with black and white, in nearly equal 

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

 broadly streaked with white; chin and throat white, streaked with black 

 or blackish slate; chest and breast plain slate-gray, the lower portion 

 of the latter sometimes showing paler tips to feathers; abdomen 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 black without trace of 

 brown or sooty tips to the feathers. 



6 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 than the majority of 

 Chiriqui examples.
