Ibis, Moshr. 



Falcinellus, Linn. 

 Very similar to Numenius, but may be distinguished from that genus by the very 

 small size of foramina in the orbital septum, there being no depression or ridge down 

 the centre of the forehead between the orbits ; the manubrial process on the sternum 

 and the fissures on the posterior margin being much smaller, the ischiadic foramen 

 amounting to a mere slit, the obturator much smaller, and the furculum stronger 

 in proportion to the size of the bird.

Harpiprion, Wagl. 



Hagedash, Sparm. 

 Cranium with occipital crest well marked, but the space of the occipital bone 

 narrow. Orbital septum with one large foramen ; a slight depression on the upper 

 surface of the cranium between the orbits. Palatine bones of moderate breadth, the 

 edges of the hinder portion bent downwards, and gradually sloped to their junction 

 with the interarticular bones, gradually narrowed anteriorly to a thin strip of bone. 

 Interarticular bones broad at their junction with the palatine bones, and much flattened 

 horizontally, gradually narrowed backwards ; hinder portion of the inferior maxillary 

 bone prolonged far backwards beyond the condyle, blunt and rounded at the end ; a 

 deep cavity at the end on the inside of this, into which the processes projecting on 

 each side at the lower part of the occipital ridge fit when the jaws are open, and from 

 which a small muscle extends to the inner edge of the cavity in the lower maxillary 

 bone.
