to an individual o£ the size of the one to which the type 

 tarso-metatarsus of that species pertained, and it is more 

 probable that it should be referred to A. dromccoides.

43085. A nearly similar left tibio-tarsus ; probably from the South 

 Island. Purchased, \S~\. 



32056*. The right tibio-tarsus of an immature individual ; from Te 

 liangatapu. llather smaller than the next specimen. 



Mantell Collection. 



32502*. The right tibio-tarsus of an immature individual ; appa- 

 rently from the South Island. The extremity of tlio 

 cnemial crest was detached and has been lost, and the 

 extensor bridge was not ossified. No history. 



21791. The distal half of the right tibio-tarsus ; from Te Rangatapu. 



Mantell Collection. 



21791 a. The distal half of the left tibio-tarsus ; from Te Ranga- 

 tapu. Mantell Collection. 



21791 b. The distal extremity of the left tibio-tarsus ; from Te 

 Rangatapu. Mantell Collection. 



21791 c. The distal portion of the right tibio-tarsus; from Te 

 Rangatapu. Mantell Collection. 



b. The Fibula. 



21763. A right fibula, probably referable to the present group; 

 from Te Rangatapu. Very like the corresponding bone 

 of the type of A. clidina. Mantell Collection. 



21763 a. A left fibula, apparently associated with the preceding. 



Mantell Collection. 



c. The Femur. 



The specimens included under this heading probably represent all the 

 more typical species of this genus. In a large series of specimens a 

 complete transition can be observed from the larger bones doubtless 

 referable to A. casuarina down to those belonging to A. didi- 

 formis and other small forms. It is equally difficult to distin- 

 guish between the stoider types nf the larger femora and the 

 corresponding hones of Emeus. 



32008 a. A right femur : probably from Kuamoa, near Oaraaru
