broadly margined with fulvous, this being the predominant 

 colour of this part of the body in the specimens from Colombia 

 and Venezuela, but much less in those from Guiana. Line 

 above and behind the eye, and one beneath, pure white. Ear 

 coverts black. Median rectrices, bronzy at base, succeeded 

 by a brownish-black bar, and tipped for one-third of their 

 length with wliite. Lateral and outermost ones bronze at 

 base, then black tipped with white. Underside ashy-gray 

 with a central stripe on throat white, and brownish-black on 

 each side. Wings purplish. Maxilla black. Mandible, red 

 with black tip. 



Total length, 6|in. Wing, 2|. Tail, 3^. Culmen, \\. 



Female. — Slightly paler on underside, especially near the 

 gular stripe, which is of a slightly darker gray than the rest. 



I have a fine series of this species from Caracas and Merida, 

 Venezuela, from British Guiana, and from Colombia. There 

 are small differences in the colouration according to localities, 

 but not enough, I think, to separate them. I believe that the 

 well-known Collector, Mr. Auguste Salle, was the first who 

 brought the species to Europe. If was dedicated to him, by 

 Mr. Bourcier.
