 bare and with fleshy papillae; feathers of neck enlarged and elongated into a ruff, 

 with corresponding "cape" behind; the latter about half as long as the former, but 

 more persistent ; entire plumage very variable ; three spring males before me pre- 

 sent the following appearance: Number one. — Entire plumage, except crissum, 

 flanks, lining of wings, chin and primaries, ochraceous-rufbus and ochraceous- 

 buff, heavily and regularly barred with black, the three shades alternating on ruff, 

 and the black of this region showing high metallic purplish reflections. Number 

 t u >o. — Crown, cape, and edges of ruff bright ochraceous ; enclosed area of ruff 

 white ; back ochraceous, finely mottled with black ; wings grayish brown to dusky ; 

 breast and sides ochraceous and black in irregular blotches. Number three (the 

 Columbus specimen). — Crown and abbreviated ruff bright tawny, mottled with 

 glossy black; throat and lower neck all around pure white; back finely mottled

 predominating, but feathers with broad edgings of brownish or buffy gray ; wings 

 fuscous or variable gray; fore-neck, breast, and sides mingled ashy gray, black, 

 and whitish ; remaining under parts white ; the black everywhere with more or 

 less of metallic reflections. Immature: Like adult female, but black less exten-

 ceous or buffy ; below fore-neck, breast, and sides buffy or buffy-ochraceous ; re-
