According to Count Berlepsch, the single female specimen obtained at Turbo during 

 Lieut. Michler's expedition to Darien belongs to this species. It was left undeter- 

 mined by Cassin, and referred to P. adolplii by Mr. Ridgway, before being submitted 

 to Count Berlepsch, whose determination we now follow. 



The species was described by Gould from trade skins from Bogota, and is now well 

 known as an inhabitant of Colombia, Ecuador, and the Valley of the Upper Amazons ; 

 in the latter district E. Bartlett found it at Chyavetas at the foot of the Andes of Peru.

■ SPHENOPEOCTUS. 

 Sphemproctus, Cabanis & Heine, Mus. Hein. iii. p. 11 ; Salv. Cat. Birds Brit. Mus. xri. p. 286. 



In this and the next genus the males all have remarkably thickened shafts to the 

 outermost three primaries of the wing, these feathers in the female being normal. 

 Whether Sphenoproctus is really distinct as a genus from Campylopterus is open to 

 question, and many writers unite them. Sphenoproctus, as its name implies, has a 

 peculiar wedge-shaped tail, and as the coloration of the species is also peculiar, the 

 two forms may be kept separate. 



Sphenoproctus contains two doubtfully distinct species, one of which belongs to 

 Mexico, the other to Guatemala.
