losed to the sternum of the skeleton marked A. The corre- 

 sponding bone (the left) is present, but is free, and shows that 

 the whole of the bone was present in the specimen figured on 

 plate Ixxxix. of the " Extinct Birds of New Zealand." 



The Scajmla.— The remaining element of the seapulo- 

 coracoid arch is represented by three specimens ; and, as the 

 exact fit of the bone with the coracoid, and the resulting angle, 

 is a matter of some considerable interest, I hope Professor 

 Parker will investigate it, and collate the results with those 

 he has so elaborately worked out in his paper on the skeleton 

 of No torn is. 



The Humerus. — This bone is represented by five specimens, 

 and has been figured and described already. The engi-aving 

 gives a good idea of the bone ; but the small tubercle oi' pro- 

 minence on the lower third of the shaft is not present in any 

 of the specimens examined by me. It should be noted that on 

 page 378 of the book Professor Owen corrects his previous 

 identification, and ascribes it to A'ptornis. 



The Femur. — Eepresented by six specimens. The pub- 

 lished figures of this important bone are not satisfactory. 



The Tibia and Fibula.— The figures on plates Ixxxiv. 

 and Ixxxvi. not being taken from very perfect bones, I hope 

 to give a figure taken from complete specimens. The meta- 

 tarsus is an exceptionally interesting bone, and quite easily 

 recognised. There were six metatarsi, and a sufficient number 

 of the phalanges to partially restore the feet. 



The ribs have not hitherto been described or identified; 

 they are of a unique character, and some have very curious 

 epipleural appendages ; others are very long and thin— very 

 diflerent from the Dinornithic ribs of the restoration on plate 

 xciv. of the " Extinct Birds of New Zealand." 



The few tracheal rings found with the skeletons are quite 

 different from those assigned to AjJtornis on plate xcii. 

 (ojj. cit.). There is no notch on the rings, and a section of the 

 circumference is merely circular, and not flat as in most of the 

 Dinornithidge. The diameter of the rings, which are oval, is 

 as 2 to 1. I am somewhat inclined, after all, to consider 

 these as belonging to AnomaloiHeryx didiformis, found in the 

 same locality.
