This bird veas 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 Eica, 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 deflned, in others they 

 are obsolete. 



We have no account of the habits of this bird, but Salmon obtained eggs of GraUa- 

 ricula cucullata, which he describes as pale coffee-colour spotted and blotched with 

 dark red-brown spots. They thus differ widely firorn the eggs of Grallaria. 



Pam. C0N0P0PHAGID51. 



This family, which is strictly South American, is not represented in the Central- 

 American fauna. With the Pteroptochidse, it differs from the other families of 

 Tracheophonge in having two pairs of notches to the distal margin of the sternum.
