This very remarkable species has nothing whatever to do with Trog- 

 lodytes musculus^ but is apparently most closely allied to T. rufescens. 

 From this it ditiers in the uniform dark chestnut color of the upper 

 surface; the ver}^ obsolete barring of wings and tail; unbarred crissum; 

 darker sides of liead and neck; and less fulvescent lower parts, the 

 side^; and flaidvs being darker and duller, the center of throat and 

 breast paler, more grayish, the latter even Avhitish.

 interest:
