This I place as a farther variety of the pre- 

 ceding species, which it resembles in habit and 

 general cast of colours. It is blackish green-gold 

 above, and white beneath, mottled or scalloped 

 with black or dark^brown on the throat, and with 

 dusky green-gold on the breast and upper part of 

 the abdomen : 'the wings are violet-black, and the 

 tail of the same colour, but the side-feathers edged 

 and tipped with white. Native of Cayenne, and 

 figured by Monsn Viellot from a specimen long 

 preserved in the French Museum, and which, as 

 he imagines, may have been the one described by
