 trasted white patches. Ground color of the sides of the head, neck and throat, purplish black, while 

 a crown stripe of jet black extends from the bill back to the occiput. On either side the crown-patch 

 is bordered in front by a narrow white line, and behind by a rich chestnut stripe. Three white 

 patches show prominently upon the face: at the base of the bill is a broad triangular one of white, 

 another round spot is situated on the ear-coverts, and still farther back on the sides of the neck is a 

 white band. A white collar, narrower underneath, and interrupted along the middle line above, 

 separates the neck from the body plumage. The slate-blue mantle color is continuous with the color 

 of the upper breast but on the side of the breast is a broad crescentic white patch bordered with 

 black. There is a conspicuous longitudinal white patch along the middle scapulars, while the back, 

 rump and upper tail-coverts shade off into deep purplish black. Tail black, with purplish reflec- 

 tions, and the central tail-feathers longer than the rest. Abdomen brown, darker posteriorly. Under 

 tail-coverts purple-black like the upper ones, with a small white spot on each side near their bases. 

 Flanks bright chestnut. Wings slaty gray, with the speculum metallic purple, and the inner sec- 

 ondaries mostly white. There are also one or two white-spotted feathers among the wing-coverts
