Layard procured an egg in New Caledonia which is undoubtedly 

 referable to a species of Pachycephala, either P. morariensis 

 or P. xanthetrcea. Prom its small size it appears to be referable 

 to the latter species, the Blue-backed Thickhead. It is smaller 

 than, but quite similar in colour to, the eggs of P. gutturalis, 

 and measures -82 by "61.
