J cjdging from the number of eggs of this species which 
have been received from Madeira it must there be a very 
common bird. In shape this egg differs from those of 
the other two species of the group, which are nearly 
oval; it is also without the zone of minute dots, but re¬ 
sembles them in the thin delicate texture of its shell. 
The egg figured is from the collection of Mr. Bond.
