Layard procured an egg in New Caledonia which is undoubtedly 

 referable to a species of Paclviceplmla, either P. morarunsis 

 or P. xantJietrcea. From 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. gutticralis, 

 and measures -82 by "61.

The eggs of the Eufous-breasted Thickhead are of an ordinary 

 oval shape, occasionally much pointed at the smaller end, and 

 moderately glossy. They are of an olive-buff colour, spotted and 

 blotched, chiefly in a zone round the broad end, with darker 

 olive or olive-brown and pale lavender-grey. They measure from 

 •85 to '9 in length, and from '6 to "68 in breadth.
