Hiipocnemis is a tolerably well-defined group of about 18 species, 

 chiefly developed in Amazonia, but extending northwards to Panama 

 and Costa llica. The bill is rather short and compressed, the wings 

 moderate, and the tail short. The tarsi are rather long, and show 

 only slight indications of the divisions of the scutes. The sexes are 

 always diff"erent, the males being invariably darker and more in- 

 tensely coloured than the females. 



In the subjoined " key " the characters are taken from the male 

 plumage only.
