 uary 17, ISO.'i, Ohas. W. Eichmond): Upper parts, including upper tail 

 coverts, sides of neck, malar region and auriculars, slate-black, almost 

 pure black on pileum; middle pair of tail feathers slate-black, with a 

 terminal black bar of 0.20 inch. Wings black, primari«'s. secoiul to 

 sixth, with outer webs edged with white; secondaries and wing-coverts 

 narrowly barred with white, bars 0.10 inch apart. A white spot before

 actly, but the barring on the wing coverts and secondaries is very differ- 

 ent, and there is a slight difference on th<'n])pcr parts, a perceptible gloss
