 The posterior margin of the sternum differs from that of aura in having only one 

 large foramen on each side of the keel ; the centre is slightly produced and pointed ; 

 the whole sternum is also more convex. The sternum is all I possess of this bird.

 The shape of the bones forming the cranium is very similar to those of the type of 

 the family, but the maxillaries are more slender. The palatine bones taper much more 

 anteriorly, are not so much deflexed on their interior edges, and have their hinder 

 extremities more angular ; the foramen magnum is not placed so perpendicularly. 



Sternum also similar to that of the type, but with two small foramina on its posterior 

 margin, the right one of which, in my specimen, is the largest.
