Male. Bill blue; head and neck anteriorly, dark-colored; the region in front 

 of the eye and on the sides of the collar behind, rich-green, this color shading into 

 purplish on the upper and under surfaces of the head ; a broad patch on each side 

 of the head from the posterior border of the eye, and meeting its fellow on the nape, 

 the lower neck all round, under parts generally, wing coverts (except the lesser) 

 and most of the secondaries, and the scapulars, white ; the latter narrowly edged 

 externally with black; rest of upper parts, except as described, black; passing

 sooty-brown, more or less tipped with white ; iris hazel. 



Female. With the entire head, neck, and upper parts almost black; an elongated
