Allied to A. australis, with which it agrees closely in size. The 

 tarso-metatursus may be distinguished by its narrower proximal 

 extremity, and by the foramen in the groove between the third

 probably in the North Island. The proximal extremitj- 

 is imperfect. This specimen agrees very closely with the 

 corresponding bone of a recent skeleton, in which the 

 length is. U,074, and the width of the proximal extremity 

 0,018. A rather larger specimen, from the superficial 

 deposits of the North Island, is figured in Owen's ' Extinct 

 Birds of New Zealand,' pi. li. figs. 7, 8. No liistonj.
