Eggs of the Brown-necked Eaven resemble those of the G. corax, 

 being clear greenish-blue, marked with different shades of brown 

 and underlying lavender. One example is merely marked with a 

 very few specks and small smears, while two others are rather 

 densely mottled. The other specimens are intermediate in colora- 

 tioD. They measure from 1"7 to 1'86 in length, and from V2 to 

 1'27 in breadth.
