As here arranged, Pithys embraces four species, distributed from 

 Costa Rica southwards over Colombia, Guiana, and Amazonia. The 

 genus is nearly allied to Myrmeciza, but has the bill shorter and 

 stouter. 



The first species, with its crested head and lengthened throat- 

 feathers, should probably, in strictness, stand alone, and the others 

 be referred to a separate genus.
