On a review of the several species of Dinornis of which the osteological structure is 
known, the following generic characters may be deduced :— 
1. Skull with a rather short, broad, moderately arched bill, not attaining the height 
of the cranium; occipital condyle not projecting so far back as the upper border of the 
occipital foramen. 
2. Horizontal palatal plates of the palatines and maxillaries more or less confluent, 
not uniting solidly, but suturally, with the premaxillary and the vomer. 
3. An Apterygian, not Dromeine, pelvis. 
4, A short, broad sternum, with small, ill-defined coracoid pits, and with three 
posterior notches. 
5. Scapula and coracoid small and feeble, forming no angle, or one of 170°, 
developing a glenoid cavity at their bony confluence. 
6. Four toes; the hallux small and high-placed. 
7. Terminal confluent caudals of less vertical extent than the antecedent free caudals.
