The eggs of the Black-chinned Flycatcher and those of the 

 following four species of this genus (P. gonldi, P. verticalis, P. guttu- 

 latus,P.loricatus) resemble each other closely and cannot be separated 

 by any character. They are of a regular oval shape and almost 

 devoid of all gloss. The ground-colour is white or pinkish white, 

 and this is very thickly speckled, especially at the broad end, with 

 bright chestnut and lavender. In many examples the markings form 

 a well-marked zone round the broad end. Two eggs of the present 

 species measure respectively : "85 by '62 ; -85 by 'ei.
