 be generically separated.

The largest representative of the genus, and the type of >Si/ornls. 

 Founded upon limb-bones from Waikouaitu, of which the tibio-tarsus 

 (not in the Museum collection) may be regarded as the actual type. 

 This bone has a length of 0,480 (19 inches) and a width at the 

 distal extremity of 0,074 (2*9 inches), the distal width thus being 

 between one sixth and one seventh of the length. The sternum 

 (fig. 62, A, p. 254) probably referable to this species has very long^ 

 and slender lateral processes and no coracoidal facets. The skull 

 referred to this species by Owen and Haast is of the relatively small 

 size of that of A. didiformis. 



This species, which exhibits great variations in point of size, ij 

 regarded by Haast as closely allied to the smaller A. didiformis, to 

 which, indeed, there appears to be a complete transition in point of 

 size through the form described as A. dromceoides. If, as may be 

 the case, the present form is only a larger race of the latter, that 

 name has the priority. If, however, A. didina be allied to or 

 identical with A. dromceoides, the latter will differ from A. didi- 

 formis by its relatively larger skull. 



Some examples of the tibio-tarsus and tarso-metatarsus of this 

 species are difficult to distinguish from the more slender varieties of 

 Emeus (jravipes and E. crassus. 



Hah. Typically the South Island, but also found in the North 

 Island.
