The eggs of Xantus's Cactus- Wren vary from a narrow to a broad 

 oval shape and are more or less glossy. They are of a creamy- white 

 ground-colour, in some cases densely mottled, the ground-colour 

 being completely hidden, in others speckled and spotted, and in 

 others again speckled and blotched, with brownish pink and lilac. 

 The markings are of a somewhat darker colour at the broad end, and 

 generally form a zone or cap at that part. Specimens measure from 

 •9 to 1-1 in length, and from -65 to -72 in breadth.
