21710. An imperfect left tarso-metatarsus agreeing nearly in size 

 •with the preceding ; from Waingongoro. 



Mantell Collection. 



21710 a. A slightly imperfect small left tarso-metatarsns, not im- 

 prohahly belonging to a female of this species ; from 

 Waingongoro. Mantell Collection. 



21712. The left metatarsus of a young individual ; from Waingon- 

 goro. The divisions between the three component elements 

 are still visible ; the tarsal moiety having been lost. 



Mantell Collection. 



21731. The axis vertebra ; from Waingongoro. This bone may be 

 distinguished from the axis of the DinornitJdda; not only 

 by its much greater elongation, but also by the larger size 

 of the haemal spine, the more intimate connection between 

 the odontoid process and the centrum, and the presence of 

 distinct prezygapophyses. Mantell Collection, 



21731 a. A similar but more imperfect axis vertebra : from the 

 same locality. Mantell Collection. 



32089. The third cervical vertebra ; from the North Island. May 

 be distinguished from the third cervical of the Dinornithidce 

 by its greater length, wide distal expansion, single neural 

 spine, larger hsemal spine, and the contour of the anterior 

 articular surface of the centrum. In all these respects it 

 resembles the corresponding vertebra oiPo7'2)7iyrio, although. 

 relatively shorter. Walter Mantell Collection, 



32092. The fourth cervical vertebra ; associated with the preceding. 

 The haemal spine is shorter than in the latter. 



Walter Mantell Collection. 



32087. The fifth cervical vertebra ; associated with the preceding. 



The haemal spine has become very small. 



Walter Mantell Collection. 



21755. The seventh (?) cervical vertebra ; from Waingongoro. In 

 this part of the neck the vertebrae begin to diminish in 

 width, although still retaining the broad neural surface. 



Mantell Collection. 



21746, The eighth (?) cervical vertebra ; apparently associated with 

 the preceding. Mantell Collection, 



32088. A similar vertebra ; from the North Island. This specimen 



is nearly perfect. Walter Mantell Collection.
