Crrprturus, Ill. 
Megapodius, Bp. 
Does not differ much from Tinamus, except in size. My specimen of Tinamus was 
much damaged, therefore would not do to figure in the first part of this work. 
Cranium small, rounded. Occipital ridge small. The foramen in the orbital septum 
Jarge. Palatine bones broad, narrowed behind to a point. Interarticular bones 
very long. 
Sternum very long ; the central and horizontal portion very narrrow ; a strip of bone 
forming each lateral edge makes between it and the central portion a large fissure on 
each side. Keel deep; the lower edge arched. 
Pelvis broad; the vertebre apparent from the upper surface ; the os pubis curved. 
Obturator foramen large; ischiadic large; in fact both the above-named foramina are 
converted into fissures, not being closed at their hinder ends; a process at the end of 
the ilium before the acetabulum. 
Ribs strong. 
Furculum small, weak ; without any process at the junction of the rami. 
Coracoids strong. 
Scapule strong, very slightly arched, blunt at the distal extremity. 
Wing bones short. 
Leg bones of moderate size.
