The eggs of Cetti's Warbler are of a broad oval form and for the 

 most part very glossy. They vary in colour from dark pink to 

 brick-red. About half of the total number of specimens in the Col- 

 lection are plain ; the other half are marked with a more or less 

 distinct zone of pale purplish specks round the larger end. They 

 measure from 'B? to "77 in length, and from -S to -58 in breadth.
