This bird was first noticed on the banks of the Napo in Eastern Ecuador, and was 
described by Mr. Sclater in 1858. We have other examples from the same country, as 
well as from Colombia, the State of Panama, and Costa Rica, the last-named country 
having furnished Mr. Lawrence with the type of his G. costaricensis. 
Considerable variation prevails between members of this species, but we are unable 
to localize them. Panama examples agree so closely with others from Ecuador that it 
seems not possible to separate them. ‘The variation chiefly affects the extent of black 
streaks on the breast and flanks: in some birds these are well defined, in others they 
are obsolete. 
We have no account of the habits of this bird, but Salmon obtained eggs of Gralla- 
ricula cucullata, which he describes as pale coffee-colour spotted and blotched with 
dark red-brown spots. ‘They thus differ widely from the eggs of Grallaria. 
Fam. CONOPOPHAGIDA, 
This family, which is strictly South American, is not represented in the Central- 
American fauna. With the Pteroptochide, it differs from the other families of 
Tracheophone in having two pairs of notches to the distal margin of the sternum.
