OSTEOLOaiA AVIUM. 



[Melaneepw^e. 



Hemilophus, Sw.

Sternum broader in proportion to its length, and much curved outwards posteriorly to 

 the junction of the ribs; fissures not so large, and differing very slightly in size. Infe- 

 rior edge of the keel very slightly arched ; anterior one with the point produced, and 

 with a slight excavation between it and the manubrial process. In other respects the
