Eggs of the South Brazilian Blue Jay vary from a wide to a 
regular oval shape, sometimes somewhat pointed towards the smaller 
end, and are very slightly glossy. The large series collected by 
Mr. Foster at Sapucay is remarkably uniform in appearance. All 
have the ground pale blue, boldly spotted and blotched with 
reddish chocolate-brown and lilac-grey of several shades. In most 
examples the markings are distributed all over the shell, but in 
one or two they are more numerous at the larger end and form an 
irregular wreath, They vary in length from 1-] to 1°32, and in 
breadth from °83 to ‘91,

Three eggs from Brazil and Serra do Mar also referred to the 
present species have a very different type of marking, the ground 
being pale greenish-blue closely freckled all over with umber-brown 
and lilac-grey. These eggs agree exactly with the figure given by 
Herr Nehrkorn.
