Professor Baird informs me that I was in error in identifying this 

 bird with Struthus canicejps of Woodhouse (which I have done in 

 P. Z. S. 1857, p. 7), the latter bird, from New Mexico, having the 

 red colour confined to the interscapularies, and not extending over 

 the wing-coverts as in the present bird.

This curious bird is placed by some authors in the Tanagrine 

 series near Buarremon. It is, 'however, remarkable for its short 

 bill and short wings, the primaries only extending "3 inch beyond 

 the secondaries, and in this latter respect comes nearer to Ember- 

 nagra ruficirgata of Lawrence. The hind claw is very short, and 

 the structure quite different from that of typical Embernagra.

This bird belongs to the same group as P. fuscus, Sw., P. meso- 

 leucus, Baird, and P. aberti, Baird, but seems specifically distinct 

 from all of them. Its clear white throat at once distinguishes it 

 from the former and latter, while from P. mesoleucus (as described 

 by Baird, and as shown by a specimen in my collection, which I 

 refer to that species) it differs in the entire absence of any rufous 

 colouring on the head, the whole upper surface being of a perfectly 

 uniform greyish brown.
