The eggs of the Olive-tree Warbler are of quite the same cha- 

 racter as those of Hypolais hypolais and H. polyglotta, but they are 

 larger and have the ground-colour rather paler. It is noteworthy, 

 however, that in the comparatively large series of the eggs of 

 this species in the Collection, not one shows any indication of the 

 cobweb-like combination of fine lines frequently found on the eggs 

 of the other two species. At best there are only a few short 

 detached lines on a few examples. A series of specimens measures 

 from '8 to *85 in length, and from *55 to # 6 in breadth. A remarkably 

 small egg measures only -67 by "53.
