 toes reaching nearly to end of tail), hind claw nearlj' or quite as long 

 as the digit, small bill (exposed culmen little if any longer than hallux,

 with very broad but subacuminate rectrices, with semi-decomposed 

 webs; color (of the single known species) mainly uniform olive-green, 

 the head mostly black. 



Bill small, much longer than deep; exposed culmen decidedly less 

 than half as long as tarsus, gently convex; basal depth of bill a little 

 less than length of gonys; maxillary tomium fainth"^ notched near tip,

 deflection; mandibular tomium straight to the distinctly but not

 ous; gonys slightly shorter than distance from nostril to tip of maxilla, 

 slightly convex, with basal angle rather prominent. Nosti-il small,
