Chalcococcyx maculatus (Gm.).  
The Emerald Cuckoo.

Chrysococcyx hodgsoni, Moore, Jerd. B. Ind. i, p. 338.
Chrysococcyx maculatus (Gm.), Hume, Cat. no. 211.

Ou the 1st of June Mr. Mandelli obtained a nest of Stachyrhidopsis ruficeps containing three fresh eggs of the usual type, and one very much larger of a nearly uniform pale pinkish chocolate.

On the 12th of July another nest of this same species was found at Lebong, which also contained three fresh eggs of the Stachyrhidopsis and another similar reddish egg. It is quite certain to my mind that the egg is that of some Cuckoo, and in ray opinion the only Cuckoo to which it can belong is Chalcococcyx maculatus. It might of course be the egg of Cuculus sonnerati, but it is, I think, too small, and differs too essentially from the Cuculus type. It is certainly not the egg of Cacomantis passerinus, the only other small Cuckoo that occurs in the neighbourhood of Lebong.

The egg is a very regular oval, scarcely, if at all, smaller at one end than the other. The shell, though small, has only a very faint gloss. The colour is most peculiar  -  a uniform pink with a certain chocolate tinge in it, and with, when closely examined, a few very minute, pale claret - coloured specks, scarcely darker than the ground, scattered about its surface.

It measures 0.8 by 0.02.
