Eggs of the Scarlet-headed Marsh-bird are of an ordinary oval 

 shape and glossy. They closely resemble eggs of the Common 

 Sono--Thrush, the ground being pale blue, sparingly marked with 

 a few small spots and irregular marks of dark purplish-black and 

 purplish-grey. They measure respectively : 1*01 by -73; 1 by "73 ; 

 1 bv '72 ; '98 by •74. These eggs agree with the description given 

 by Hudson, but not with that given by Burmeister. Nehrkorii 

 describes the ground-colour as yellowish-white.
