Genus V. Phlogopsis. 



Phlegopsis, Reich. Nat. Syst. d. V6g. pi. 57. (1850). 



Rostrum forte, compressiusculum, naribus parvis, rotundatis, an- 

 tice positis ; regione oculari nuda ; narium plumis erectis et 

 setosis : pedes modici ; acrotarsiis vix conspicue divisis ; para- 

 tarsiis integris, u?igue postico brevi, incurvato. 



This section is at once distinguished from Formicarius by the for- 

 ward position of the small, rounded nostrils and nudity of the ocular 

 region, which in Formicarius is densely feathered. The hind claw 

 is also remarkably short and thick.
