The middle trochlea does not project forwards so much as 

 in C. curta or P. geranoides, and in this point again our species 

 resembles A. didiformis. The inner trochlea is not produced 

 so much as in M. didina or P. geranoides, but resembles that 

 of C. curta and A. didiformis ; it is, however, narrower in pro- 

 portion to its depth than in either of those species. It agrees 

 with A. didiformis in the more transverse direction of its an- 

 terior face, which in G. curta and in P. geranoides is directed 

 almost to the inner edge of the middle trochlea. 



The intertrochlear gorge is broader than in C. curta, but 

 does not narrow so much at the entrance as in A. didiformis 

 and all the other moas. 



It thus appears that, while it has distinctive characters of 

 its own, the affinities of A. antiqua are more closely with 

 A. didiformis than with any other species. It differs, however, 

 from A. didiformis in the narrowness and in the shape of the 

 lower surface of the inner trochlea ; in the shape of the inter- 

 trochlear gorge ; in the more rapid tapering of the middle 

 trochlea ; in the double sinuation of the anterior margin of the 

 proximal articular surface ; and in the small inner hypotarsal 

 ridge. The length of the metatarsus is not known, but the 

 tibia is considerably shorter than that of A . didiformis. 



It will thus be seen that my inference that the rnoa bones 

 from Timaru belonged probably to the genus Anomalopteryx 

 was a correct one.
