"The three sets of eggs, while they have a mutual general resem- 

 blance, differ greatly in details of coloration, as do also the eggs of the 

 same set. In one set the ground-color in one egg is dull pale creamy 

 white, while in the other it is a much deeper shade of the same color ; 

 in the other eggs it is of about the same shade as in the paler egg of 

 this set. The markings, generally of a very pale chocolate mixed with 

 lilac shades, in the first set nearly cover the eggs, especially in the 

 darker egg, while in the other set of two eggs they are sparser and 

 coarser; in the single egg of the other set they are nearly all massed 

 in a nearly solid broad ring about the greater end of the egg."
