 Ad. St. Zool. See. Coll. 



t In one species, P. ■montagnii, the ebin ar.d upper part of the throat are 

 usually, but not always, covered with feath2rs. On this character Sclater and 

 Salvin, P. Z. S. 1870, p. 521, founded the genus Stegnolama, but as the chin 

 and throat are sometimes nearly naked, and in the nearly allied P. sclateri and 

 P. argi/rotis (which they leave in Penelope) these parts are sometimes partially 

 feathered, I do not consider it necessary to retain Stegnolama.
