The eggs of the Hammer-headed Stork appear to be usually 

 of an elliptical shape, but some are oval. They are dull white in 

 colour, rather smooth to the touch, very slightly pitted with pores, 

 and perfectly without gloss. They measure from 1'63 to 1*9 in 

 length, and from 1*17 to 1*42 in breadth.

 blunt oval form, approaching the elliptical. It is much stained, 

 but was apparently, when fresh, dull white in colour. The shell 

 is coarse and chalky and has no gloss. This example measures 

 3-6 by 2-3.

The eggs of the Herons and Bitterns are indifferently of an oval, 

 elliptical, or biconical shape, and in every large series eggs of these 

 three shapes will be found to be about equally represented. The 

 texture of the shell is somewhat rough and chalky. 



The eggs are always unspotted and, with few exceptions, of a 

 blue colour. When the series is large, the majority of the speci- 

 mens will be found to be of the same blue colour as the eggs of the 

 Common Heron (Ardea cinerea) and Notoplioyx novce-hollandi^ m 

 (Plate V. fig. 1), but a few will be paler, resembling the egg of
