The eggs of the Icterino Tree-Warbler are of a regular oval form 

 and possess a small amount of gloss. The ground-colour varies from 

 greyish pink to pale brownish pink or salmon-pink, and is marked 

 ml her sparingly with spots of deep purplish brown or black. The 

 spots on some specimens are very small, on others large, but they 

 are always well-defined. A few examples are also marked with 

 short lines and streaks, while others are covered with very fine 

 lines which run over the shell in all directions and resemble the 

 lines of a cobweb. The underlying markings are obsolete and 

 often absent. Specimens measure from *G7 to -81 in length, and 

 from "51 to -56 in breadth.
