This peculiar Tauager in style of plumage and general habit cor- 

 responds mest closely with the members of the genus Arremon, but 

 the bill is altogether abnormal, the upper mandible swelling in the 

 middle and overlapping the under, as in the genus Lanio, thougk 

 not developed into a decided hook : but it is much shorter, broader 

 and deeper than in the last-named genus, and has more general re- 

 semblance to that of some of the Saltatores.
