Birds of New Zealand. 213 



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, but 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 difl'erent 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 othei's, 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
