This bird occurs occasionally in collections imported from 
Bahia. I have two adult and one young specimen, the latter 
agreeing well with the figures of the supposed S. undulatus.

This species is rather divergent in structure from its fel¬ 
lows, having a stronger bill, longer and thicker tarsi, and a 
longer hind toe and claw. When I first obtained specimens 
of it in one of Verreaux's Napo collections, I proposed to 
refer it to a new genus and species, Agathopus micropterus.
