Mus. P. L. S. 
I have three Chilian skins of this bird, and two from 
Ecuador which I cannot distinguish except in the legs being 
rather darker. One of my Chilian skins was received from 
Landbeck as his Pteroptochus alhifrons. But the white ter¬ 
minations of the head-feathers, which are very slight, are, in 
my opinion, only sexual, and perhaps seasonal. 
I have not seen the young of this species; but it probably 
has a brown plumage, as in other species of the genus.
