THE HONEY-GUIDES 171 



dark chaetura drab to dark olive brown, the next pair similar but 

 with the inner web largely white, except terminally, the subsequent 

 pau's with the white extending progressively over more and more of 

 the outer web as well, but all of them broadly tipped with dark olive 

 brown, these dusky terminal areas continuing basally along the outer 

 edge of the outer web of each feather a short distance; auriculars 

 grayish white; chin and throat like the lores but even darker, more 

 blackish, sharply defined from the rest of the underparts which are 

 white washed with pale drab gray, this wash usually strongest on the 

 breast and upper abdomen, and weakest posteriorly; a few of the 

 feathers of the flanks and thighs with dark olive brown narrow shaft 

 streaks; under tail-coverts white; under wing-coverts similar but 

 usually more heavily tinged with pale drab ; bill pinkish white (varies 

 in different individuals from strongly pinkish to gi'ayish white to 

 pale brown, the pink color disappearing from specimens after death; 

 bill darker, more bro^vnish in first adult plumaged birds, and (possibly) 

 in birds in the nonbreeding season — this last still subject to further 

 elucidation before it may be said to be definitely known) ; iris brown; 

 tarsi and toes dark bluish green to dark plumbeous gray. Measure- 

 ments in millimeters: wing 107-119, tail 67-78, culmen 13-15.5, 

 tarsus 16-18. Weight, 58.8 grams. 



Adult female: Similar to the adult male but with the general 

 coloration of the top of the head and the upperparts generally some- 

 what paler — olive brown, sometimes with a buffy tinge; the forehead 

 and lores even slightly paler, the chin and throat whitish tinged with 

 drab, like the rest of the underparts; the pale edges of the greater, 

 median, and outer lesser upper wing-coverts less whitish, more pale 

 drab, the yellow edges of the inner lesser upper wing-coverts less bright, 

 slightly darker as a rule; occasional very old females acquire some 

 black feathers on the throat. Measurements in millimeters: wing 

 96-110, tail 54-68; culmen 11-13, tarsus 16-18. 



Juvenal (sexes alike): Entire top and sides of head, nape, inter- 

 scapulars, scapulars, upper wing-coverts, remiges, and back chaetura 

 drab to dark olive brov/n with a wash of dark citrine to olive green, 

 this tinge most pronounced on the forehead, crown, upper wing- 

 coverts and on the edges of the median and greater upper wing-coverts 

 and of the remiges, particularly of the secondaries; the remiges 

 internally edged with whitish (hidden in closed wing) ; feathers of the 

 rump and the upper tail-coverts white forming a conspicuous area of 

 white (which is streaked with olive brown in the adults), although 

 occasionally some of the feathers have some laterosubterminal blotches 

 of brown; rectrices as in the adult but with the brown terminolateral 

 patches on the outer rectrices usually somewhat smaller; chin, throat, 

 and breast Naples yellow to pale mustard yellow ; rest of underparts of
