white colour, smeared and blotched with lavender-grey and marked 

 with black specks, spots, small blotches, and twisted hair-lines. 

 The markings sometimes extend over the whole shell, but more 

 frequently they are almost entirely confined to the broader half of 

 the egg. The black hair-lines are wanting in some specimens. 

 Examples measure from -57 to *65 in length, and from *45 to '52 

 in breadth.

The eggs of the Booted Tree- Warbler are much smaller than 

 those of Hypolais hypolais and H. polyglotta, but are of precisely the 

 same colour and marked in a similar manner. They measure from 

 58 to '66 in length, and from -45 to *5 in breadth.
