In outline the eggs of the Eusset Sickle-winged Chat-Eobin 

 vary from a narrow to a broad oval. They are of the same glossy 

 blue colour as those of P. cinerea, but rather smaller. Some are 

 perfectly plain, others are indistinctly freckled with very pale 

 rufous at the broad end. Examples measure from -7 to -83 in 

 length, and from -55 to -62 in breadth.

The eggs of the Familiar Chat have a rather bright blue ground- 

 colour, with a very variable amount of light rufous and reddish- 

 brown markings. One clutch of three eggs is absolutely spotless, 

 other specimens are faintly dotted with rust-colour, mostly at the 

 larger end, while two are quite thickly streaked and spotted. They 

 range from "73 to So in length, and from '58 to -62 in breadth.
