I have one male specimen from Colombia so distinct in its 

 colouration that a new species could be made with it ; but I 

 consider that it is only accidental. It is as follows : — Upper- 

 side dark green with a bluish tinge. Rectrices of tail steel- 

 blue. Underside purplish-gray, washed all over with bluish- 

 green feathers. Undertail coverts white. Wings purple. 

 Bill black.
