Birds of New Zealand. 
former, with a hallux and hind toe; tibia straighter and with¬ 
out the extremities so enlarged as in Palapteryx; sternum 
longer than broad, more concave than the former genus, with¬ 
out coracoid depressions, hut with strong and long costal pro¬ 
cesses, mesial portion and process comparatively longer than 
in all the former subdivisions, no bony scapulo-coracoid, beak 
not so obtuse as in the former.

2. Euryapteryx rheides. 
In the preceding list I have only entered those well-defined 
species of which we possess ample material for comparison 
and generalization, leaving several others, of which we ob¬ 
tained only portions, for a future notice; but amongst them 
I may at least allude to one species which appears to ap¬ 
proach the Emu of Australia in its general characteristics. 
I had also formed the intention to add some notes on the 
crania of the different genera, but fear that it would make 
this address too long were I to give them here. 
However, before proceeding, there is one point to which I 
wish to draw your attention-—namely, to the existence or ab¬ 
sence of a bony scapulo-coracoid. In the genus Dinornis we 
find deep and well-defined coracoid depressions in the ante¬ 
rior border of the sternum of each species; and the excava¬ 
tions have furnished us with a series of scapulo-coracoids 
which fit exactly into these depressions. Moreover these 
small and peculiar bones, by their form and size, agree also 
in other respects well with the different species enumerated. 
However, when we examine the sternums of the genus Pa¬ 
lapteryx, and principally that of Palapteryx elephantopus , we 
meet some with well-marked depressions, others with only 
faint ones; whilst there are others, belonging apparently to 
aged birds, where there is not the least appearance of them. 
Again, we possess a few sternums in which a depression exists 
on the one side, whilst it is missing on the other; so that we 
are compelled to conclude that no bony scapulo-coracoid 
could articulate with them. 
Moreover we have never found any scapulo-coracoids of a
