 Two others are of a pinkish cream-colour, mottled and spotted with 

 pale rufous. They measure respectively : 1"8 by 1-32 ; 1*76 by 1-28 ;

The eggs of the Orange-chested Hobby vary from a broad oval 

 to a pyriform shape. They are smooth in texture and without gloss. 

 Two examples in the series are cream-coloured, profusely smeared 

 with two shades of brown. The others have a ])ale blue ground 

 and are marked at one end or the other with confluent blotches of 

 umber-brown, the other portions of the shell being very sparingly 

 spotted with the same. Nine specimens measure from 1-5 to 1-6 

 in length, and from 1-19 to 1-25 in breadth. These dimensions 

 are much smaller than those given by the American authors 

 quoted above. It is probable that Chilian birds of this species 

 are much smaller than North-American examples.
