Adult male. Similar to that of C. verticaJis, but the crown usually 

 of a deeper purple tint and the tail a shining bronzy-reddish hue. 



Young birds have a dark crown without blue lustrous feathers, 

 and a slight tinge of buff on the sides of the neck and the flanks. 



This bii'd is very closely allied to 0. verticalis, but may be dis- 

 tinguished by the reddish-bronze colour of the tail : the sides, too, 

 of the neck appear to be rather greener than in that bird.
