With the bones of the hitds are associated fragments of large birds' eggs noticed

 The cranial portion of this skull is intermediate in size between that figured in pi. 38^ 

 fi.s 1-4. and that in pi. 39. figs. 4, 5 & 6, of my former Memoir (Part H-). P- 307, and

 Dinornis casuarinus. The following are a few of the comparative dimensions of these 

 crania, and of one referable to the Palapteryx geranoides.
