The eggs of the Crested Hangnest are of a regular oval shape, 

 slightly glossy and of coarse texture. They appear to be very 

 variable in colour. Two specimens have the ground white and 

 two others have it pale greenish-blue, and they are both 

 sparingly spotted and blotched with deep black and lilac. Two 

 other examples are pale pinkish-white mottled and smeared with 

 lilac-grey. In addition, one is covered with a close tracery of fine 

 purplish-brown lines, and the other is marked with a few blackish 

 spots and blotches and some irregular lines of purplish-grey. They 

 measure from T25 to 1'4 in length, and from -9 to 1 in breadth.

The eggs of Salmon's Hangnest are of a narrow oval shape, with- 

 out gloss and slightly coarse in texture. They are of two types. 

 In the first they are pinkish-white, blotched and smeared with two 

 shades of sepia-brown and with underlying lavender-grey. In the 

 second, the eggs are salmon-pink, spotted and mottled with pale 

 reddish-brown and lilac-grey, and marked, in addition, with a few 

 lines and specks of deep purplish-brown. They measure from 1*37 

 to 1-5 in length, and from *94 to 1 in breadth.
