 lower outlines slightly curved, tip of upper mandible slightly over- 

 hanging and notched ; cutting edge of upper mandible slightly sinu- 

 ate ; wing formula nearly as in Clilorospingus, 9th primary slightly 

 longer than longest secondary ; 8th a little shorter than 6th and 7th 

 which are subequal and longest ; longest primaries about length of 

 culmen longer than secondaries ; three outer pairs of tail feathers 

 graduated enough to produce a distinctly but not strongly rounded 

 tail ; tarsus unusually thick with short strong toes and claws ; middle 

 toe with claw about three-fourths length of tarsus ; tarsus less than 

 one-third length of wing and less than half the length of tail.

 olive green ; under parts greenish yellow becoming more orange
