sensibly iuto it; bare orbital space surrounded hj black, this mucli 

 broadest above the eye, where forming a large longitudinal patch, widest 

 posteriorly, on each side of the red crown ; remainder of the head smoky 

 olive-gray, lighter on the forehead, the frontlet, cheeks, and chin more 

 or less strongly washed with golden yellow; throat, juguhmi, breast, 

 sides, and upper part of abdomen, uniform smokj^ ft'i'ay; middle of the 

 abdomen stained, more or less deeply, with golden yellow; tibia?,, anal 

 region, and crissum thickly marked with V-shaped bars of black. Up- 

 per parts sharply, and rather broadly, barred with black and white, the 

 bars of the two colors nearly equal in width ; i)rimaries black, bordered 

 terminally with white, and marked at the base (of outer webs) with 

 large blotches of the same; jirimary coverts uniform black; lower rump 

 and upper tail-coverts white, with rather distant broad bars of black. 

 Tail black, the intermediw broadly barred, on both webs, with white; 

 lateral pair of rectrices distinctly barred on both webs, to the base, with 

 white, the bars not touching the shaft, however, except near the end of 

 the feather; next tail-feather usually barred on the inner web only, 

 the next two wholly black or with mere indications of biirs. Adult 9: 

 No red on the crown or occiput, which are uniform ash-gray, the occiput 

 sometimes (but rarely) blackish, in consequence of the coalescence of 

 the black supraocular patches. Young $: Similar to the adult, but 

 colors of the head less brilliant, and all the markings of the plumage 

 less sharply defined ; light bars of the dorsal region obscured by an oli- 

 vaceous wash. Wing, 4.50-4.00; tail, 3.10-3.00; culmen, .05-1.10; tar- 

 sus, .85-.90. 



In this handsome species there is rather an unusual amount of indi- 

 vidual variation. In the adult males, the bright Indian-yellow of the 

 nape is usually quite distinctly defined against the red of the occiput 

 and crown; but in one (No. 26091, Mazatlan), only the lower margin of 

 the nape is yellow, the rest being bright red, like the occiput. In this 

 example the frontlet, chin, cheeks, and auriculars are a bright golden 

 yellow, while the jugulum and breast are darker and more olivaceous 

 than in others. In the adult females the red of the crown and occiput 

 is usually wholly replaced by uniform rather light brownish gray; but 

 sometimes (as in Xo. 23817, Mazatlan, J. Xantus), the whole occiput is 

 black, while it is not unfrequently spotted with this color. Further- 

 more, in this example, also in two others (Xos. 23752 and 39977, Mazat- 

 lan), the nape is intense orange red with merely a lower border of yellow.
