bones short, flattened, articulated in the centre, with the alse of the sphenoid vomer 

 wanting. Condyloid portions of the occipital bones not very strongly developed. 



Vertebra? strong and broad, as among the Vultures generally. 



Sternum very convex, inferior edge of the keel very much arched ; the anterior point 

 not receding; the edge much scolloped out; the sternum narrower posteriorly than 

 anteriorly ; the hinder margin produced into a point in the centre, from which it recedes 

 in a slight curve to the lateral edges. Manubrial process with the point triangular. 



Felvinal bones similar to Sarcoramphus, but with the ischiadic foramina larger and 

 more oval. 



Furculum with the rami slightly rounded ; the process at their junction well developed. 



Coracoi&s very wide at their articulation with the sternum, and extending nearly to 

 its full width ; axillary foramen situated low down. 



Scapula long and strong, without any central depression, transversely expanded at its 

 junction with the coracoid. 



Humerus moderately expanded at its proximal extremity, with the ridge to which the 

 pectorals are attached much bent outwards. Ulna much flattened, slightly triangular. 



Femur with the trochanters highly developed, very short in proportion to the tibia 

 and metatarsus. 



Tibia very long, with the head very large. 



Fibula extending for two-thirds its length, and anchylosed to the tibia for its upper 

 third, and again at its inferior extremity. 



Metatarsus similar in form to Sarcoramphus Papa, but much lengthened and more 



slender.
