344 KEW BIRDS FROM COSTA EICA CHKRRIE. 



the Atlantic side by examples from Colon ( Aspinwall), Costa Rica, Nica- 

 ragua, Honduras, and Guatemala, there are seen certain differences 

 that appear to be constant and which do not seem to be due to age, 

 season, or sex. 



A male (true (mrantiirostris, I believe) from Pozo Azul, Costa Eica 

 (Pacific side), (No. 1178, Museo Nacional de Costa Eica, January-, 1887, 

 J. C. Zeledon) may be described as follows: Above, olive-green; head, 

 black, with a median vertical cinereous stripe ; superciliary stripe, ashy 

 white, whiter anteriorly and more ashy posteriori}'; wings" and tail, 

 dusk}' brownish edged with olive, that on the tail much the darker; 

 bend of wing, lemon-yellow. Below, sides of face and chin, black ; throat, 

 white; pectoral band, black; sides and flanks, slate-gray, tinged with 

 olive on the flanks; center of belly, white; under tail coverts, brown- 

 ish-gray. (Jctober and December birds from the same locality show 

 little variation ; but a bird taken in May, 1881, a female (No. 101838, 

 U. S. National Museum, Pozo Azul, Costa Rica, J, C. Zeledon), has the 

 strijie on the head darker gra3'ish. The olive-green is perhaps a shade 

 brighter, while in the center of the back are a few brownish feathers 

 (the same color — nearly a chestnut — as on the bird described by Cassin 

 as ruf odor salts , No. 39041, U. S. National Museum). The black pectoral 

 band is not so well defined, the sides and flanks are washed more with 

 grayish olive, the abdomen is buffy, the under tail-coverts brownish 

 fsepia). Another example from Panama has the under tail coverts a 

 wood- brown. 



A male from Choctum, Vera Paz (Guatemala) (No. 20121, U. S. Na- 

 tional Museum, Vera Paz, January, 18G0, O. Salvin), may be de.-^cribed 

 as follows: Above, dark olive-green, a brownish shading on the upper 

 tail coverfs; head, black, median vertical stripe, gray; superciliary stri[)e, 

 white; wings and tail, dusky brownish or blackish, edged with brownish 

 olive-green. On the tail the edging is only visible at the base, where it 

 is very dark; bend of wing, light orange-yellow; below, sides of face and 

 chin, black; throat, white; broad black pectoral biind ; center of breast, 

 white, shading into buffy white on the abdomen; sides and flanks olive- 

 brown, with faint shadings of olive-green ; under tail-coverts clove- 

 brown. Two specimens from Talamanca, Costa Rica, male and female, 

 taken in April, have the sides and flanks more decidedly washed with 

 olive-green, the under tail-coverts a trifle lighter (sepia-brown), while 

 the beml of the wing is a bright orange yellow. Another Costa Rica 

 specimen (No. 1175, IMuseo Nacional de Costa Rica) is probably melan- 

 istic. Above it is dark brownish olive green; wings, tail, and tail-coverts 

 dark brownish (clove-brown), tail and coverts darkest, with scarcely a 

 shade of olive edging except on the wingcoverts; bend of the wing is 

 rather bright orange-yellow; below the center of the breast is white, 

 and only a shade of buffy on the abdomen; sides and flanks, brownish 

 olive; under tail-coverts, sepia-brown. An example from Los Sabalos, 

 Nicaragua, a female, taken in April, has the back a little brighter olive.
