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

 with black specka, spots, small blotches, and twisted hair-lmes. 

 The markings sometimes extend over the whole shell, but more

 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. pnlyglotta, 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.

In the majority of the characteristic eggs of the Barred Warbler, 

 the pale bluish-grey or neutral-tint markings underlie the dull 

 greyish or buffish-white ground-colour, and there is no surface-
