Subfamily IV. HUPICOLIN^E. 



Rupicola, with its large feet and extraordinary compressed crest, is 

 certainly one of the most specialized forms of the American Passeres, 

 but does not appear to present any very remarkable deviations from 

 other Oligophonine Passeres in internal structure. But Garrod 

 (P. Z. S. 1877, p. 517) has shown that, unlike most of the Cotingidce, 

 it is Homaeoinerine and not Heteromerine, and has therefore placed 

 it in a separate group of the Oligophonaj. 



Near Rupicola must come Phcenicocercus, I think, although much 

 less abnormal in structure. Both these forms are restricted to the 

 Guianas and Amazonia.
