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

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

 secondaries, the eighth shorter than the first), and much rounded tail 

 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 faintly notched near tip, 

 thence nearh^ straight to the very slight, almost inappreciable, basal 

 deflection; mandibular tomium straight to the distinctly but not 

 prominently toothed subbasal angle, the basal deflection inconspicu- 

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

 slightly convex, with basal angle rather prominent. Nostril small,
